Hi Everybody
Happy New Year and long time no speak
My Miggys still going strong and drives great
Good old Symes did tracking for me recently and a full service on her
I've got a problem though, while driving her she's fine, but when coming to a stop or sat at lights etc, I get a very strong whiff of oil!
Driving me insane as Syme recently cleaned my breathers out and she goes much better
The smell of oil has only started after I had an oil change
Any ideas why I'm getting this whiff which has lasted about 6 weeks??!
I've got no steam coming from the rocker covers
Symes gonna look at these next Sunday
But thought I'd ask on here incase anyone else has ever had this Oil whiff!!? lol
-
Usually failed cam cover gaskets leaking oil on the manifold heat shield, drivers side is in front of the pollen filter to the cabin. Air flow does the rest.
-
Okey dokey
Even though theirs no effect on performance of the car?
When I do have new ones put on
Will I notice a difference in MPG and anything else?
-
How much is all the kit i need from Vauxhall?

Usual detriment is missfires caused by oil leaking into the spark plug wells. If its running fine that suggests its only the outside edges of the cam covers leaking, or the oil hadn't eaten the spark plug lead caps yet.
Unless its misfiring, you will notice no problems at all. ...apart from the smell of oil of course ;D
...is the oil cap secure, along with the filler neck?

£70/80 from vx only for the gaskets. If the leads are buggered price them up from a factors. Euro car parts do a set for under £50 last I looked. Dont use vx for leads they are over £100 a side.
-
Ps. Don't panic, it's fairly normal on these. But don't leave it, deal with it ASAP. 6 weeks is too long really Wayne. ;)
-
Cheers Chris :y
Syme did check for oil in the plug wells about 2 weeks ago, all clear mate
Hopefully can get it sorted next Sunday
I've noticed the idling revs going up and down when stood still
Hopefully when gaskets are replaced, she'll go even better
-
I only do 40 miles a week over 4 days
So I'll try not to drive her until my drive to Oxford next Sunday
(About 22 miles)
-
You should clear the breathers at the same time as replacing cam cover gaskets. The gaskets blow when the breathers are blocked and the crank case pressure finds some other way of escaping.
-
Breathers been done mate, they we're full of crap.. They we're done about 3 weeks ago
-
Rang Vauxhall, told me the gaskets and o rings don't come with sealant and it's not needed?
Is this True?
Price for the above including VAT is £101 ouch!!!
-
Have a look for the oil leak before buying any parts. Given that it started when the oil was changed, I'd make sure the oil filter housing is not leaking. ;)
-
Okay mate
-
Got the same happening on mine . No apparent leaks and only oily smell when pulling up after running :(
-
I open bonnet when engi ???ne is hot an no smoke . Nothing

Yes it is needed.
Trade club brings the price down. Maybe Symes can help you there?
But as Kev says, you or someone needs to find the oil leak first before spending any money.
As with any fault, correct diagnosis first, open wallet second. :)

I've yet to see a v engine with no oil leak, of some kind or other. So your not looking/trying hard enough. :P
Obviously if your smelling oil, then it's getting hot, so exhaust is a good place to start.

Although, are you sure its engine oil? ATF is subtly different, and coolant has that burnt sugar twang to it.
-
No defitnately oil engine oil smell . Spark plug wells dry an breathers clean ???
Best look underneath on exhaust ???
-
Possibly sump gasket or sump plug , all wet oil on sump pan :'(
-
oil pump o ring for pressure switch just below cam covers is a favourite place for leaks on my 2.6 then got blown back onto sump & further back worth a look.
-

Yes that's where all the oil ends up. Every omega I've ever seen has a pool of oil sitting on top of the sump and, to varying degrees, where it gets blown back on to the subframe cross member and then gear box and beyond in extreme cases.
But the point is, all those cars have an oil leak including mine, but NOT all those cars have a smell of burning oil. Mine does not smell of oil either.
So, it's the added scope of "burning" or "smell" of oil that is the clue here. This requires heat to happen, and the obvious place to start there is oil on the exhaust or related parts.
If the sump is getting hot enough to cause a smell of burning oil then there's far more serious concerns with the engine than a simple oil leak. ;)
-
I think I have a similar problem, and being a novice I don't know where the breathers are - help, please?
Ron.

Worth a look ;)
So we all have oil burners :D ;D
Ps. Where about's , what side is oil pump oring pressure switch ???

Wow, what a fantastic and comprehensive reply, BlackViper - much appreciated.
Thanks a million.
Just a little 1/2 hour job, then!

Your welcome Ron :)
Makes a change for me to guide someone else rather than me always asking questions, lol 8)

Harking back to an earlier comment about oil residues causing this type of problem; when I had a Carlton, my garage advised that vx did NOT recommend flushing oil prior to an oil change. Is this true of Omegas, because to my simple mind such a strategy would seem to be helpful here, and nobody ever explained why flushing was a bad thing.
Ron.
P.S. People have been so helpful on here and I only wish I could help in return, but my expertise isn't likely to be helpful here: I was a Lecturer in Electronics and Radio (and photography!) at Chelmsford College for the 20 years before I retired, having spent the previous years as a Design/Development Engineer in industry.

No experience personally, but Master always says...along the lines of...
"Flushing can cause large lumps of congealed oil deposits to drop into the sump and block the oil pick up."
I have seen partially blocked oil pick ups on the omega, they don't need any extra help from flushing.
Low mileage oil changes are far better as it wears down deposits gradually, and the oil stays cleaner long term. Say 2 or 3 quick oil changes 3k apart, add some wynns lifter treatment if its noisy from cold, then continue with 5k oil changes from there for the duration.
Ignore the vx service schedule on oil changes, its designed to Impress fleet buyers, with no concern for your engines ling term use.
Semi synth, oil and filter every 5k. :)

Chrisgixer, I thought I was the only one to have oil sitting on the top of the sump pan. My CC gaskets has never leaked but were changed and sump has been resealed so where does this oil come from? I also get a faint whiff of oil when I'm out of the car or have the window open when stationary
-
Remeber its an Omega built by Vauxhall and they are incontinent when it comes to holding any forms of fluid..oil/coolant etc ;D

Should have seen my facelift then, dry as a bone when sold and always was

Where to start... There's an exploded view of the crank cases in the web but I'm buggered if I can find it.
There's two sump seals, the steal sump has a sensor in at the base screws to an alloy casting, this casting can leak on its seal to the block and the subframe fouls removal. Then there's the various apertures in the block itself, oil pump as mentioned earlier, dip stick tube seal, oil pressure switch, front crank seal.
Then at the top there's the cam seals and obviously the cam cover seals.
All of these can leak down, it all ends up on top of the sump. Very difficult to spot due to surrounding parts, cam belt covers, auxiliary parts, exhaust heat shields etc.
Rear crank seal leaks into the bell housing. Only seen one of these though, and it had had gear box work prior to, which coincided with the start of the leak.

Mine leaked from the rear crank seal ..... no work on either engine or gearbox. ;)
I chickened out & paid someone else to fit the GM supplied seal (£30-odd IIRC :o ) but later had to fit down pipe to manifold exhaust seals instead of the exhaust paste they'd used and clip the lambda sensor wires to the gearbox rather than let them flap about in the breeze. :-X

My first 2.5 had a weeping rear crank seal :'( Hope its not that :'( Although i noticed a wiff off oil when it was started from cold yesterday :-\

Chrisgixer, can any of those lead to a major oil leak? Or can I put my mind at rest with the knowledge that It's a vauxhall and they all do this ;D

Some have more then 1 dont they :-X :-X

Going back to the original post. As you've had an oil change, you sure you haven't spilt a small amount of oil down the filler pipe onto the manifold and it's just burning off.
I know it can be a bit tricky getting that first spout of oil in the neck if you're not using a funnel ;)

You've got one of the cheap ones then, mine were built by Opel. ;D

That's my way of thinking, it has to be said ;D just turn the Radio up, it'll be fine. :D

Might be off the mark but have you checked to see if any of the cam cover bolts are loose?

Yep, always worth a look they do come loose.

Guys
Picking my rocker cover gaskets from VX tomorrow
what is the part number for the sealant i need to get while I'm there
Before when my gaskets went, I had the common "steam" coming from the bonnet
But this time nothing.. Still smelling of oil
Going to see Symes this Sunday for him to check all possibilities
