Well all I know is that on the Omega you MUST fit genuine gaskets, with black sealant, or they will soon leak. ;) ;)
Sure it must be the same with Vectra's covers, even though they are metal.
-
when I did my cam gakets I used gen VX. They seem to be the only ones recommended on here as the cheapo ones are rubbish apparently, and for a fraction of the price I bet they are!
I've also heard that vectra cam covers aren't advised either, don't know why though, someone else will tell you soon.
-
The plastic cam covers on the omega has different gaskets to the vectra metal ones. Make sure you get the right ones.

because when your breathers are blocked, the increased pressure will blow your rear crank shaft seal first instead of the cam cover gaskets. Although a rear crank seal is quite cheap, they're a bugger to fit ..... the gearbo has to be removed. :-?

pay cheap pay twice, pattern do not last! Geniune gaskets, genuine black sealant, not green
Why the Vectra cam covers? Your better off with the stock plastic ones.
I did my camcover at about 105k miles, with genuine parts, its not leaked in several years and 45k!
Fresh oil and clean breathers prevents the gaskets blowing :y

.....
Geniune gaskets, genuine black sealant, not green as per the guide. ......
I wonder how long orange Loctite (http://www.onlinebearings.co.uk/images/P/loctite_574_lg.jpg) lasts? ::) ::)

Does it smell of oranges too? :D
How much is it?
Know some people have used various types of Loctite, but i've never had any issues with GM's Black sealant, and as its a job thats done once every 100k or so, i'll stick with it for when the others need doing.
-
The other problem with Vectra cam covers is that they need fitting the wrong way around really, to keep the filler in the correct place, and that means the plug holes won't line up properly putting strain on the leads... Your call, but I'd just use genuine Vx parts and the original covers, unless they are cracked, and pay attention to the low torque value. Mine, like TB's were done about 55k ago and don't leak ;)

Not quite, more like silicon ;)
How much is it?...
Don't know, stores doesn't have a price list .... came from a previous stores :y :y

clean your breathers regularly enough and you dont need to be buggering about with cam covers. the "MUST fit genuine gaskets" claim isnt strictly true, and the gaskets for the metal cam covers are the same if i recall, as i use them on my cavalier AND my omega(s). obviously any OE part is going to be a better fit but that doesnt mean that ALL pattern parts are crap. autovaux supply some excellent fitting items that work fine. i have had no problem with them since fitting a year ago.

No, they are different. Vectra B metal ones use different gaskets to omega plastic ones.

He is right :y
Also your filler will be in rather an arkward place when you want to do an oil change ::)
-
Mine, like TB's were done about 55k ago and don't leak ;)
Wouldn't be surprised if mine may need changing again soon - they have been off about 3 times since then, reusing same gaskets ::)
-
These are the gaskets you need , they are good quality, and because they have a much greater contact area than the standard omega gasket they wont leak EVER as long as you take care when fitting them, IE carefully degrease both mating surfaces using meths or similar and be sure to use a dab of the correct black sealant in the right places at the 'corners' around the cam seals and the half moons at the back, and as said keep the breathing system clean. Filling with oil is no problem as long as you use a funnel :y

I certainly would advise against fitting vectra metal covers.

Mine had a little weep for ages but found that some of the bolts were a little loose... Tightened them again and all been fine since.
But then, mine haven't been off since :-X ::)

I'd second that. I have seen cars with them having dreadful misfire issues due to the offset plug holes.
But... It's your car, your money and your choice :y :y
But we've warned you! ::) ;D

Offset plug holes? Theres no problem with my omega fitted with vectra covers, the plug leads fit perfectly and it certainly dosent misfire.

Does the 2.6 engine have different covers in the vectra b? I believe that the 3.2 uses the same covers in both the vectra c and on the omega :-/ Neither the op or bent valve have said exactly which engines they have.

Wasn't it Veccy C before they got the 2.6? :-/ :-/
Like I said... I wouldn't fit them but each to their own. I prefer to know that the weakest point in the system is easily visible :y
-
If memory still works:
Vectra b 2.5 '95-'99, then 2.6 '99-'02.
Vectra c 3.2 '02-'55, then 2.8t '55-'09.
I think from all the previous noise that the vectra b uses different covers/gaskets for packaging reasons, the engine being the wrong way round and all. (The car being a fwd tat box, not withstanding). :-/

In these postings the need to clean breathers regularly is stressed, how often is regularly, obviously depends on how the car is used ie long or short journeys but is there a rough guide

Frequent oil changes (3k or so) will reduce the need to clean the breathers as much. I check mine annually but they have been perfectly clear for the last 2 years.
If you go 10k between oil changes then I'd say you probably need to clean them every oil change ;)
-
i check mine every 12 - 18 months but as lazydocker says it depends on your service intervals and also the amount of use your car gets. you'll notice a big difference in performance if the buggers are clogged:

Very sorry to The Boy about that remark.. but I do have a good excuse. I was drunk. And I am sure he knows a lot more about engines than I do about computers :-[

Oh you are so wrong - I know sod all about computers or engines ;D
