Just got those this morning. I have some time till my night shift starts so I'll prepare my miggy for cam gasket replace. It cost 110eur all together so I hope it'll work as it should. Wish me luck

You'll be fine. Onc e you've got all the rubbish outj of the way, easy, just go slow, and make sure when you put the cam covers back on you don't move/knock out of place the gaskets. Have a good evening, and a drink when you're finished!  8)

...After putting some old rag in the inlets!!! I once dropped a nut in there (onto a piece of rag I had just put in moments before) Trust me, stuffing rag in the dividers is the best thing you'll ever do in your life!

Looking good, though, keep up the good work  :)

I believe it's the same price as yours - without trade card discount. The gaskets - for both banks- were 75eur with discount. It's 54eur per bank otherwise

Um... didn't know there was a time? It was years ago since I did mine, but don't recall waiting. Ah, unless you're thinking of letting the sealant go off, so maybe 12 hours?

Well the result is - wrong driver side (your driver side  :P ) is dry and ok for now. Other side is still smoking a bit....I hope it's just an oil  residue from previous gasket leak  :( Will see about that if it stops othervise I'll just repeat the procedure I guess. Thanks for help guys
Title: Re: I hope this works
Post by: Sir Tigger KC on 20 April 2015, 21:19:08
If it's still leaking, then it's likely your cam cover has gone out of shape.  :(
Title: Re: I hope this works
Post by: danzigfan on 20 April 2015, 21:23:54
You're right, it could be because leak is at the front where the half moon is - right side looking towards the engine - always the same spot. We'll see if it clears after some time - still hoping

I came from work and went to motorway for 4 miles, I don't know what to do anymore :-[
Title: Re: I hope this works
Post by: deviator on 21 April 2015, 08:53:55
If you cleaned out all the gasket faces, used sealant in the right places and torqued it down to 8Nm using the spiral routine, then as said above - it looks like warped cam covers.
Title: Re: I hope this works
Post by: danzigfan on 21 April 2015, 09:10:16
I went to check on covers now...now this will be an amateur question - cam covers "cover" edges of the head nicely but as I move my hand along the head, the edge of cover is moved away from the head (on the side) in the middle and goes back into the corner of the head. Like it's to wide in the middle - goes over the enge of the head. I hope you understand what I'm trying to say :-[
Title: Re: I hope this works
Post by: Sir Tigger KC on 21 April 2015, 09:20:29
Yes they tend to 'spread' either through being over tightened or maybe just through age and heat.  :(

I expect if you take it off and line the long side along a ruler or some other straight edge, you will see it bows outwards in the middle and that is what is causing your leak.  :(
Title: Re: I hope this works
Post by: danzigfan on 21 April 2015, 09:28:02
I'm assuming that too sir tigger. Anyone knows what is the price for new pair of cam covers maybe?  :(
I do have a 3.0 omega sorned close to me but I don't know if it's worth to try removing those just to find them warped too :-[
Or I can go aluminum covers route from ebay and keep breathers clean.... :-\

Post by: Diamond Black Geezer on 21 April 2015, 10:32:29
Surely someone can provide him with some good used camcovers? Even with postage to Slovenia, still got to be better than 200?

Post in the Wanted Section, I'm sure you won't have long to wait.

Oh - important question - do you have a torque wrench that goes down to 8nm? - it's basically impossible to guess this figure, and is critical to avoid warping, as said.

That's the main cause I'd think as 8nm really dosn't feel very tight and it's always tempting to nip them up a bit more...  ::)  However even if they've always been correctly fitted, age and heat must take their toll as well as they're made of plastic.  :-\ 

My friendly stealer once told me that when they serviced Devon & Cornwall Constabulary's Omegas back in the day, they always fitted new covers and gaskets when they started to leak.  :-\  Taxpayers footing the bill though!  ::)  ;D

I got a pair of straight cam covers of sorned 3.0 omega just a mile away. Took it off and replaced those with mine. After 5 hours transplantation is done and holding well for now.

Title: Re: I hope this works
Post by: 05omegav6 on 25 April 2015, 22:20:43
Yes, eight bolts, all in the same place, the coil pack cut outs allow easier plug access and allow any condensation to evaporate out as the engine warms up...

Gaskets fit as well.

Remember that the 3.0 was sold elsewhere as a Dbw engine... ::)

A 205/65/15 wheel and tyre will fit along with 3 235/45/17s but its just wrong. Personally I would rather fit the correct ones
Title: Re: I hope this works

I fully agree with the sentiment Pete, but the question was would they fit and the answer is yes ;)
Title: Re: I hope this works
Post by: chrisgixer on 26 April 2015, 11:47:44
Thing is though, having asked if they fit the op might not be too impressed when he tries to fit spark plug leads to his coil pack cam covers. He needs to be able to make an informed decision.

Which he now will be able to do. So we got there :y
Title: Re: I hope this works
Post by: 05omegav6 on 26 April 2015, 12:14:18
The plug leads ought to be a secure fit on the plugs, the shape of the hole in the cam cover is largely irrelevant... and if their available locally (given OPs location)and cheaply they would be fine as a stop gap until the correct ones are fitted if it is felt they are required.

At the very least they will confirm that the old covers were indeed the cause of the oil leak ;)

Title: Re: I hope this works

I noticed it myself, only thing blocked was a small hole in the breather bridge on the plenum. Maybe it looks stupid but I tried blowing into those hoses installed  after cleaning and there was no blockage anywhere.

Guys......it's a failed attempt again >:( >:(
Why the hell does hasket hold when I'm driving arround town and then fail when I go to motorway???? Is it a oil pressure problem there or what?!?
I just came from short 3 mile motorway drive, going 70mph and the engine is like a steam engine again....lifted the bonnet and horrid smell came out of clouds of both sides of the engine. Diffinately not a residue ffs... >:(  I guess I need to search for problem somewhere else, not gaskets, not covers.

Another thing crossed my mind. I had aux belt snept of due to failed tensioner on motorway a month ago or two...being only a 1/4 of a mile from exit I put it into N and proceed with momentum to parking lot there. Could I have damaged something by doing this? :'( :'( :'(

Breathers are clean as new...metal covers are really the last option before nervous breakdown :-X ::)

If they are clean there's something wrong, as they SHOULD have a film of oil from the crank case fumes. Can you remove the pipes at the back of the plenum breather box (Eco tech black box) and blow through them? You should be able to hear the air physically blowing into the crank case one way, and the plenum the other.

You can attach and air line, or even blow through them with your mouth if needed.


Basically the entire inlet, from behind the throttle valve, throughout the plenum, to the valve stems should be covered in a film of oil.

Same for you shak, they should be oily. If not they are most likely blocked.
Title: Re: I hope this works
Post by: danzigfan on 27 April 2015, 07:12:42
I did that when the plenum was of and I could hear air coming from the under plenum part, no blockage was there AFAIK :'( this is becoming frustrating..
Title: Re: I hope this works
Post by: danzigfan on 27 April 2015, 07:14:27
And when I sprayed some carb cleaner into the breather hoses - all of them - it all went down , no blockage anywhere

Does the air reach the crank case blowing the other way?

There is a breather box behind cylinder 5. Two pipes attach there. 1 large. 1 small. These must blow through to the crank case, or they are blocked.

This three unattached hoses go to breather box right?
If I block larhe hose and blow into another Ifeel the resistance. I can hear hissing from plenum but I get my pressure back in the face when I stop  >:(. The pressure when I blow comes out of the small unattached hose in the pic BUT poorly...lot of resistance

When I did cam covers I didn't take out breather box but I only took a piece of small wire and pushed it trough the small hose inlet just to see it's not blocked....and it wasn't :-\ :-[  Should I unbolt breather box to find if it's blocked inside? As I was reading how to's and experiences I thought it was enough to do that
Title: Re: I hope this works
Post by: 05omegav6 on 27 April 2015, 07:49:33
All depends on how the car was treated before you bought it...

There is a picture here somewhere of the insides of the box, which helps to understand how it blocks up.

A small wire might well clear the hole, but your effectively making a hole in soft oily residue, so won't take much to block it up, even if you have successfully cleared a hole all the way through... :-\

Best thing is to acquire another box, soak it overnight in a bowl of petrol, then leave to dry in the sun, followed by a quick go in the dishwasher.

Once thoroughly clean fit to the car, but bear in mind that it requires grey goo, same as oil cooler, so will need time to cure before using the car :y
Title: Re: I hope this works

As I need to remove plenum, injectors and all unnecesary stuff away that would be the easyest acces to the breather box remove I guess.

Just force I paper clip, or similar diameter item through the small hole in the breather box brass pipe, and dig out any crap in the large bore pipe. There's no need to go any further than that as far as clearing the alloy breather box goes. There is nothing to be gained by removing it.

There is a guide on this somewhere.

Ps I have had the box off before. You have to destroy the rivet to open it. It's not complex just a baffel plate. Nothing more in there.

Just force something through to clear any blockage. :y

Although strictly speaking the grey goo is the correct stuff to seal the breather box.  Any decent automotive sealant/instant gasket such as Hylomar will do the job just as well and will be a lot cheaper.  ;)

ie Tube of grey goo £11-ish tube of Hylomar £4-ish.  :y

Could it happen that breather box is blocked down at the lower two big holes which go into the crank? The rubber flap inside I mean.  It's going down anyway and to soak in gasoline for a while, don't want to be half done again
Title: Re: I hope this works
Post by: chrisgixer on 27 April 2015, 20:52:56


Mine, in the pictures, was blocked on the small brass insert hole. It caused no major issues. In order to cause the problems your seeing , assuming correct installation of the cam covers, there would need to be a lot more gas being blocked by the breathers. So it does "sound" like there is no breather function at all. As normally the breather system is enough to keep the crank case at negative pressure.

So, possibles;
Breathers blocked
Engine producing more crank case pressure than the breathers where designed for
Incorrectly fitted seals. In some way.
Title: Re: I hope this works

Title: Re: I hope this works
Post by: chrisgixer on 27 April 2015, 21:08:27
Before modifying anything, such as alloy cam covers, insure the basics are correct.

Mainly that ALL the breathers pass air/fumes in both directions via the hoses at the back. At risk of repeating, if they don't flow air, work your way back to the offending blocked holes either in the plastic Eco tech box, which can easily be removed and a paper clip forced through the holes and cleared.  But don't make the holes bigger in any way or the engine will use too much oil.

If you can't clear the alloy breather box with small implements then you'll have no choice but to remove it and investigate further. The oil film and gunk on the inside of that box can dry to an exceptionally hard and brittle film that can cover the small hole on the inside. It just films over and sets. I can't explain about the large bore hole as I never had issues with it but I have seen pics of it fully gunked up with crap.

If alloy covers are fitted and the problem isn't rectified the pressure will simply burst out somewhere else. Next in line is usually the front or rear crank seals. These are awkward, time consuming and expensive to replace. Beyond the scope of most diy mechanics. Although some here have done so.
Title: Re: I hope this works
Post by: danzigfan on 27 April 2015, 21:12:38
Thanks Chrisgixer again. I have no intention to fit alloy cam covers if there's too much pressure in system...I need to find the cause first I know. In next two days.Thank you again

BUT ....no matter how hard I try I can't blow trough the tube or suck (when I block small hole and the other part of"Y" hose) , the resistance is there though both tubes are clear. It seems the breather itself is blocked at the lower part....so it'll need to come out....I hate it >:( >:( >:(

The "Y" piece was flushed with more than a liter of gasoline, there was a lot of gunk inside but is clear now. Small tube is clear too.
Is there going to be anything wrong if try a motorway run with dipstick lifted a bit? Just to release pressure out if in case there's some unundentified fault somewhere else?

I went on motorway with oil dipstick not fully closed - stoped and checked - smoke on both sides

Could there be any of those small wacuum hoses plugged on the wrong place? Could it even result in such way I'm experiencing now?
I really don't know anymore :'(
Title: Re: I hope this works
Post by: danzigfan on 29 April 2015, 12:43:13
When does  the "Y" hose "engage" into engine operating ? There is suction on small two middle plenum breather but no vacuum on "Y" piece. Does it create underpressure when running at higher rpm and then start sucking trough "Y" pipes?
Title: Re: I hope this works
Post by: Kevin Wood on 29 April 2015, 16:18:34
The Y piece goes to the breathers before the throttle, so it's normal for there to be no suction there.

At idle / slow running, the small breather pipe has manifold vacuum on it, air is purged from the crankcase through this pipe and is replaced by clean air entering through the Y pipe.

At full throttle, the engine breathes through the Y piece to a point upstream of the throttles. The smaller breather pipe does practically nothing due to the small diameter with very little vacuum across it.

Maybe it's worth checking the breather box behind the 1,2,3 cam cover? Could be blocked, perhaps?

Mind you, leaving the dipstick out would probably have eliminated any pressure in the crankcase. :-\
Title: Re: I hope this works
Post by: danzigfan on 29 April 2015, 16:22:34
Sory for being retard but breather box behind 1,2,3? I'm sorry ... :-[
Breather box is clean although I didn't remove it, checked it by blowing into it and air passes trough without problem

Title: Re: I hope this works
Post by: danzigfan on 29 April 2015, 18:54:11
Another stupid question, sorry  :-[ The breather box itself has two inlets from the crank side judging by the pics.
Are those two inlets connected to different "chambers" or both to the same chamber? I hope you understand what I'm trying to say ....Is bottom of the breather box divided in two inlets because there are two different system under it that need each their own breather (one with rubber flap and one without) or are those two connected to one chamber... Damn sorry that's just the only way I can ask what I want to know... :-[
Title: Re: I hope this works
Post by: chrisgixer on 29 April 2015, 19:09:35
Clean, but does it flow air.

Can it be blown through? Block one and blow through the other. Etc

Big one looks like it's been cleared out? Was it blocked?


[Edit to add. Shit there's two more pages I have missed. I meant in response to your last pics.]

You might need to remove the breather box from behind cylinder 5. Then check it's clear inside.
Title: Re: I hope this works
Post by: danzigfan on 29 April 2015, 19:33:47
Air flows, if I block small tube and one of the "Y" part and blow into it air comes out trough oil dipstick tube without any difficulties. So I guess it's not blocked. And by looking into the back of the engine bay today I rrally can't imagine how could I remove breather box. I could only see one bolt there other three were hidden very good :'(
 And I even managed to squeeze 10 inch of strong wire into it with some struggling due to inside of breather box. Wire was strong enough not to wind down at the bottom of the box.
Title: Re: I hope this works
Post by: chrisgixer on 29 April 2015, 19:50:47
The breather box does come out. As Daz advised me when I had to remove mine, the heat shield is covering the second bolt, but heat shield is very easy to bend out of the way, so you can get to the second bolt.

You will need to remove the scuttle, a magnet on a stick and some grey sealant for refitting, as used on the oil cooler cover plate. I have some here but it's old.
Title: Re: I hope this works
Post by: chrisgixer on 29 April 2015, 19:55:02
But.... If you can blow through the breather box that should be enough, I would of thought.


Is the Eco tech box clear to blow through in the same way? Has it been removed and inspected with cleared pin holes into the plenum? Apologies if you said so before.
Title: Re: I hope this works
Post by: danzigfan on 29 April 2015, 20:25:57
Ecotec breather is flushed and clean, suction can be felt on small middle tubes when engine is running so I think that's ok
Title: Re: I hope this works
Post by: chrisgixer on 29 April 2015, 20:39:46
Ok. If that's all done, then question for all.


Does that leave badly fitted seals. Or engine producing too much crank case pressure?

Anything else?

I fitted aftermarket gasket the same one twice - always leaking badly. Then I bought gm gasket and o rings, fitted first time started leaking after motorway run then was leaking constantly. After that I cleaned breathers again, and repeated the procedure for forth time all together.
This time gasket holds short journeys or let's say it holds when I drive with a brick under gas pedal. When I go to motorway it's all fine , no performance problem ar anything untill I stop and then smell of burnt oil enters the cabin and I get two pillars of smoke from under the bonnet one on each side >:(
I don't know why gaskets don't hold on motorway

When crap an gunk is poked down into the breather box say over a few years im guessing that it is possible for all that crap to accumulate and eventually block totally  :-\ I would have a go at taking it off and give it a good soak and clear out just to rule it out  :)

But tommorow at 2am I need to go to work agin, this time 40 miles away.

I don't think so. I think yours was suffering from blocked breathers. But yes, fingers crossed. Might be worth a can of gunk and careful use of a jet wash to get the oil off. Obviously avoiding any electrics etc.
