Hi All.
I've got 2 problems that I need some help with...1 serious and 1 niggly one.
The serious one is that today I started work on changing my cam cover gasket.....and when I removed the Coil Pack there was Oil in the centre two wells.
Top and bottom one's were fine...just the other two.
I'm worried because the Oil seemed to have a slight Orange tinge to it.
I was fearing the worst because when I was removing the cam cover bolts, the top left one had the same coloured Oil on the very bottom of it.....all the others were fine.
My niggly problem is I need some advice on removing the Cam sensor.
I need to know if I remove the entire plug or just a section of it.
The wires from the loom go down onto a small rectangular section......the section is about the same thickness but a little wider then the end of a 10 amp fuse.
Does this section pull out and away from the rest of the plug or does the entire lot come out together in one go.
I have been pulling on the small rectangular bit but it won't budge.
I don't want to get some pliers on it and give it a real good go untill I know for sure.
I have a 2.2 C.D Facelift (y reg)
Please help......anybody!!!!!!! :-[ :-[ :-[ :-[ :-[

Oil in plug wells don't worry too much about it, only in 2 wells just means its not totally failed!
Cam sensor, pop off the Aux belt (15mm spring load tensioner) and take off the cambelt cover, up the very top, in-between the cams is a little bolt, 6/7mm at a guess (can't remember) take that out.
Unplug the loom connector to the cam sensor, the whole unit, sensor and metal 'Y' bit will come out as one unit.
Replace with genuine sensor :y

Tunnie....thanks for your reply mate, but I really am not mechanicaly minded so I need you to explain so a Doughnut like me can understand :-[ :-[
When you say don't worry about the oil in the wells as it means that it has'nt completly failed......what is it exactly that has'nt failed completly :-[
Also where abouts is the Aux belt :-[ :-[

Ok, the silver bit on top of the engine, with all the bolts in, is called the "cam cover" (not to be confused with cambelt cover)
This is my guide for cam cover gasket replacement, pictures will help!
http://www.omegaowners.com/forum/YaBB.pl?num=1225024176
The cam cover is plastic, this makes the seal to the top of the engine block, where the cams are, this of course is big oily mess, so the cover is used to seal it. As its plastic to metal, a rubber gasket is used.
This over time, hardens, and no longer keeps a good seal, oil leaks out of the covers, and around the spark plug wells, oil will leak into them. They can go any manner of colours, as water/crap from the engine bay will make its way down as well.
Use some cheapo paper towels to soak up the oil, and re-fit as per my guide above, its a real nice little job on 2.2 unlike those b@strd V6's!
The aux belt is the bit at the front of the engine, the big belt which spins around when engine is running, it drives thing like power steering and the alternator :)
There is a tensioner (keeps belt tight) bottom right, 15mm spanner on this pulled upwards, releases the tension allowing the belt to come off. There are bolts around the cam cover that just unscrew :y

Tunnie...Believe it or not I have already memorised your excellent guide to replacing the Cam cover Gasket.
I popped up to my local library and printed the whole thing off.
It's now in a folder sitting in my house, It's the only reason I know how to change a cam cover gasket :) :) :)
What confused me a little when you mentioned the Aux belt is that you did'nt mention it in your guide.
You just said to use a small flat head screwdriver as It's a bit fiddly.
What I've done so far is remove the 3 Breathers, disconnect the coil pack loom connecter at the back of the ecotech cover, remove the ecotech cover, removed all of the cam cover bolts and taken out the coil pack.
I have then simply been trying to disconnect the cam sensor by pulling on it....is that a definate no-go then?
Is removing the aux belt the only way? :-? :-?
Thankyou for your time by the way mate :y :y
-
No problem :y
Printed it off? I should make a book! ;D
To clarify, the cam sensor only needs to be unplugged for the cam cover gasket replacement. Its my fault, I miss-understood your post, I thought you wanted to remove the cam-sensor completely :-[
To unplug it, simple get a small flat head screwdriver, and gently lift the plastic lock flap on the loom connector. Forget which side its on, but put a torch on it, you will see a little black plastic 'flap' which locks onto the sensor. Put screw driver in there to prise it open a little, and lift the electrical connector up and off :y
The sensor itself will stay in place, sorry for the confusion!
-
Please please don't apologise mate.
If it was'nt for your guide which you so kindly created and uploaded to the forum, I would be paying a mechanic my hard earned money to do a job that I can now do myself :y :y :y
I was going to ask you why I need to replace the cam sensor but I did'nt want you thinking I was being funny ;D ;D ;D
And finally, and I promise to leave you in peace after this, that electrical connecter that unplugs from the sensor, is that the rectangular shaped thing that I was trying to explain in my first post....just want to be 110% sure.
Thanks a Million...your a gentleman :y :y :y :y :y :y :y

No Problem :y
Cam Cover on 2.2 is a nice easy job, nothing gets in the way, that guide was the first time I did that job, I spent all day doing it, rather than the couple of hours a mechanic would bodge though.
Its a very satisfying job, its not leaked yet and I've done 52k since I replaced it :)

I can't help, but as Tunnie didn't spot your last qustion, here it is again:

Hopefully I'll have that satisfied feeling soon tunnie.
I take it thats a Yes on the rectangular shaped thingymejig ;) ;) ;)
-
Sorry yes it is that rectangle connector, its the only sensor/wire at the front of the ecotec cover.
In my defence, I scan read these and type fast. I am supposed to be working ::) :-X ;D

Excellent....Cheers Tunnie....will update on my hopefully finished job as soon as I can..... :y :y :y :y :y :y

Hi guys.
Well yesterday after cleaning out the Oil from the plug wells I made the decision to replace the Spark plugs.
As I had everything opened up in front of me due to me changing the Cam cover Gasket, I thought it would be a wasted oppertunity not to change them for some nice new one's.
However when I removed the old plugs the tips of them were covered in Oil :-[ :-[
I would say that about a quarter of the thread of the plugs had Oil on it.
Worried out of my head now....can't put the new plugs in or re-assemble the cam cover untill I know if this is normal or if I have a problem..............Help!!!!!!! :-[ :-[ :-[
-
On the 2.2 its unusual for oil to enter the cylinders, with Oil cooler is possible on V6, but can't see it happening on the 4 pots :-/
Its usually coolant that gets in around the failed HG, as the HG usually pops around the back one, number 4 due to the heat.
Have you been loosing any oil? Are you sure when removing it, somehow oil got onto the tip?
-
I have been losing a bit of Oil but I just assumed that was due to the cam cover gasket leaking.
Before I removed the old plugs I soaked up almost all of the Oil that was sitting on top of the plugs in the wells with some kitchen towel as you recommended.
Was only a tiny bit left in each well that I literaly could'nt get to......and that was not enough to soak the bottom half inch of them like they were.
All 4 plugs were the same.
I've changed the cam cover gasket, cleaned everything up so it's all spick and span, bought a brand new set of Bosch spark plugs and even bought 3 brand new breather tubes from Vauxhall.
I just can't put it all back together again untill I know what's what.
The old breather tubes were not badly blocked or anything, it's just that you can get 3 new one's for £20.73 all in so I thought why not.
Should I just put the old plugs back in and wait untill I find out the problem or put the new one's in :-[ :-[ :-[
-
Put the new plugs in :) - Do you get any blue smoke out of the exhaust when running?
-
I think you may have been right in one of your previous replies Tunnie :)
Like I said before, due to the old cam cover gasket leaking the plug wells were filled up with Oil.
I said that the amount of Oil that I was unable to soak up with old kitchen towel was not enough to soak the ends of the plugs as badly as what they were.
I think I was wrong :-[ :-[
I say this because before I put the new Bosch plugs in, I put the old one's back in and then removed them again to see if the bottoms were soaked in Oil.........they were'nt!!!!! :y :y
There was only a faint layer of oil on them which I'm pretty sure came off the thread of the plug wells which I could'nt clean.
So new plugs have now been inserted and car taken for a spin and I'm over the moon to report that my new cam cover gasket is not leaking.
Thanks to your excellent step by step guide I have auctualy done a really good job :y :y :y
The most elaborate mechanical work I had ever done previously was an oil and filter change so I'm feeling pretty Smug 8-) 8-)
Just to finish off I'd like to say that the reason why It's sometimes's taken me ages to reply to your posts Tunnie is because my Laptop is broke so I have had to keep popping up to my local library to use their computers.
Worth it though :y :y
-
Nice to hear another satisfied OOF user. :y :y :y
-
Glad to hear it went well, cam cover on 4 pots is a very satisfying little job :)
Your on the road now, once you've done something like that you'll have the confidence to attack other jobs :y
