8 months ago, my mechanic (which proved to be a really bad mechanic) has toke the cam covers, clean both of them and replaced with new gaskets.
Some cleaning etc and the old oil burned smell went way for 5 months or so!
Now after changing the engine oil I'm getting the oil level a little bit lower and plenty of burned oil smell. I suspect that I will have to redo the cam covers gasket...
In the way I've read about making the cam cover mod (aluminium X25XE to X30XE) and I came across with breathers cleaning while reading...
First it is the cam cover mod a option?
Second, I've been trying to understand how the breather cleaning job can it be achieved but no clue. Is there any proper tutorial?
-
There is a guide in maintenance section on cleaning breathers[it's a pretty straight forward job] Alloy cam covers can be used but
1] They put the oil filler cap in a more awkward to use place
2] As far as I understand it if alloy covers are used any future blockage of the breather system or other pressure issues can result in the rear crankshaft oil seal failing instead of cam cover gaskets.This is a much more difficult and therefore costly job to do.
As a result fitting alloy covers generally not a recommended "upgrade".Others will no doubt be along to advise better.

Cleaning crankcase breather system tutorial is in the maintenance guide section under "V6 engine section " :y
Someone may post you a link to it . . . but I cant :-[ :-[
Cam cover gaskets must be genuine GM gaskets . . .not cheap pattern as they will almost always have a very short life before leaks occur again :( :( alloy covers not recommended by most on here as this just pushes the problem elsewhere at greater expense. . . . crankshaft oil seals ::) ::) ::)
I hope this helps you :y
-
So cam covers mod is out of question...
I got the link http://www.omegaowners.com/forum/index.php?topic=90653.0 (http://www.omegaowners.com/forum/index.php?topic=90653.0) :)
About the cam cover gasket replacement is it a difficult job to do?
-
Straightforward enough :y
Given you don't trust the mechanic who did the work previously, I would consider buying new covers, with seals, from GM... they have a tendency to warp if over tightened, meaning they will never seal successfully :-\
-
There is an aluminium 'oil separator' box behind bank 1 cylinder head that the two breather hoses connect to. The smaller pipe connection only has a small hole in it to limit the quantity of fumes that are sucked into the inlet manifold.
The first Omega I had must have been neglected or clocked (or both) and I found that this aluminium box was almost full of solidified gunge and the small hole was blocked. I gave up trying to clean the box and bought a new one. With a new oil separator box, clean breathers and new cam cover gaskets it didn't leak again in 70000 miles :y

Bearing in mind the OP's background, he lives in Portugal, as well as he possibly struggles a bit with our language, IMO I don't see this as a issue . Admin will move it if they consider it will cause a problem .
I also notice that no one who has answered his post, myself included, had advised or suggested that he puts it in the right section, in this case & for the OP's future posting, this sort of Omega based question should go into "Omega General Help" & not General Disscussion :y

Covers are about 3 years and are GM...
Seals replaced second time.
I really do not trust none of the mechanics that have assisted the Omega.
They have big hands and at the end there are always parts missing
During the last repairs I came across with loads of missing parts mostly screws and rubbers... broken plastics and bent tubes etc I will have have a lot to put in place.
The official dealer have asked me for 490€ + vat for the idle air control valve plus labbor!
I cant afford that and even if I could I wouldn't pay that much is wrong!
-

I'm terrible sorry for the inconvenience.

Idle air control valve,if that's the bit I'm thinking of[with a rubber hose going to the front of it an electrical connector to the back and pushed into side of plenum]then although I can't recall how much I paid for one-but they're not hugely expensive-they're only a couple of minutes to fit,so 490 euros sounds a heck of a lot too much!

That,s what thought so I started to investigate and found out how cheap it was I ordered from internet and replaced by my self...

Well done :y it looks like the UK & internet are your best options for parts ;) ;)

You bet, I've found quite a number of shops with good prices and great services in uk.
To name a few:
genuinepartsearch.co.uk
vauxhallworldparts.com
lmfvauxhall.co.uk
sparepartstore24.co.uk
And there is always ebay.co.uk, amazon.co.uk...
I'm glad to say that I'm one of the last owners of an Opel Omega MV6 3.0 in Portugal, less than 5 running on petrol.
You can still see a few running on diesel from time to time. I've only saw one like mine in all these years!
But maintenance is terrible expensive, what can I do, I really love this car great great vehicle!
I wish I have a community like yours... thank you very much for your support.

I replaced the cam covers on mine fir the alloy covers from a Vectra and have had no problems whatsoever in the past 18months since they have been fitted.... :y

And you're aware of the possible problems in future ?
-
So long as he keeps an eye on the breathers (which we all should be doing, but invariably get busy with life) there's no issue with fitting alloy covers. :)
Alloy covers not for me, personally, but so long as you're aware of the risks, no issue. :)

I'm aware of that by now :) How many breather should I keep an eye on?
Only in inlet manifold and throttle body breathers or there are more?
-
You're aware of keeping an eye on them, but don't know how many there are? haha, rolls eyes. :)
Ok, the long black part on the engine top, marked 'EcoTec', contains 4 pipes/tubes. These need to be clear. Also then the pipes that come off the end of this piece at the back. Two of these go onto the metal box in the picture above, by Andy H. The inside builds up sludge/rubbish/crud but the holes will need to be clear.
Getting to it all can give you back pain, but it's worth it :y

Where's the box located at?
Can't figure it out...

The box I believe is the bigger circumference the hoses are the smaller circumference...
Do I need any gasket to refit the box?
-
Yes, you're right, the box is 'the bigger circumference'. You don't need a gasket because you don't need to remove it to clean it, simply use a drill bit of the correct size (as it says in the link / url I posted) to clean the inlet/outlets of the pipe.
The 'smaller circumference' you say are connected to the breather bridge (ecotec black plastic piece) but there are four pipes in total which need to be clear. These are easy to see when you are sitting on top of the engine. :y
-
(http://s14.postimg.org/q2kzphofl/Open_End.png)
I assume that the other end of the hose is open correct?
-
Yes. It will be clear when you look at the engine, but that pipe, and the thicker one next to it both connect to the 'ecotec' plastic part on the top of the engine. :)
-
Something wrong about "my pipes" ;D
As far as I know I got one open :-\
(http://s4.postimg.org/pnob01ehp/hose_open.png)
-
Don't worry, so long as you have 4 pipes connected to the rear of the breather bridge /Ecotec part of the engine, you're fine. That open pipe is the breather for the gearbox oil.
Just make sure it's tucked away somewhere pointed away where muck/dust/water can't get inside. That's a line straight down into your gearbox :y
-
I have always wondered about this hose.
I suppose the mechanic might have made some changes!
Do you think that a small filter would be ok?
-
They're supposed to be like that, that's how they left the factory. Most automatic cars have some form of open pipe like that somewhere in the engine bay. Just tuck it behind the engine and you'll be fine.
I bend mine so the open end points downwards, so nothing can get in. :)
-
I had done it but I was afraid I was doing something wrong ;D
I guess my thoughts were right...
