It's about £70 for a set genuine, I wouldn't take the chances given the work involved especially on the 246 bank
Yes it's quick to slap some new gaskets in, but to fit them squeaky clean and dry takes some time.... why do it twice?
The 3.2, before it's all built back up, will have new GM gaskets without fail, especialy while I don't have any pesky looms etc in the way :y

which bit of ...
V6 cam covers (not warped) - £40 collected, £50 posted.
is wrong ???
-
hi entwood cheers for that....was just wondering if the 3l v6 would fit the 2.5??? if they do am on to it :)
-
Cam covers for ALL V6's are the same ..
part no 55351453 - right hand
part no 55351452 - left hand with oil filler aperture
according to my EPC .... but get confirmation from someone who knows more than me ...
:)

Cheers....i did think that but thinking is expensive :-[

The 2.6 and 3.2 V6 Engines are significantly different to the 2.5 and 3.0 V6 due to the fact the former use coil packs per bank, which bolt directly to the cylinder head, whereas the latter utilises an earlier design incorporating HT leads :y

ahhh .. right ... further delving into EPC ...
part no 55351453 - right hand
part no 55351452 - left hand with oil filler aperture
are the 2.6 / 3.2 covers ...
90501637
and 90501638
are the 2.5 / 3.0 covers
so thanks to James we see that 3.0 will fit 2.5 ... :)
-
Yes 3.0 and 2.5 both covers and gaskets are entirely interchangeable..... :y :y

Later 2.5/3.0 camcovers include the fixings for coilpacks, which might suggest that the 3.2/2.6 ones will also fit perfectly... ::)

This is incorrect
Later 2.5 and 3.0 HEADS have the bolt hole fixings for the 2.6 and 3.2 coil packs, but the 2.5 and 3.0 cam covers are totally different to the 2.6 and 3.2 ones

They are easily distinguishable because the 2.5 and 3.0 ones have round holes for HT leads, whereas the 2.6 and 3.2 ones have square apertures for the coil packs...
-
Ah ok the later 3.0 Catera camcovers must be 2.6/3.2 ones then ::)
Given as that's the only reason the later 2.5/3.0 heads have the coil pack holes...

The pic you have posted there is a drive by wire engine which utilises 2.6/3.2 cam covers and a coil pack per bank
In omega form, there was never a 3.0 drive by wire engine.
Therefore in omega terms, omega 2.6 or 3.2 cam covers will NOT fit a 3.0 omega
-
They're the same heads on a variation of the same block.
Of course the Omega B was sold as a Chevrolet and a Cadillac, both with DBW 3.0 engines. But no, because the badge says different you insist on splitting hairs...

I'm not splitting hairs,
The op wants cam covers for a 3.0 OMEGA
I have (correctly) informed him that cam covers from a 2.6 or 3.2 OMEGA will not fit
Which is the correct advice!
The fact the 3.2 covers may fit a 3.0 DBW catera is totally irrelevant
There was never a 3.0 omega in DBW form
This is an OMEGA forum. The OP is hardly likely to source parts from a breaking Catera. I therefore maintain that 2.6 or 3.2 cam covers from an OMEGA are not suitable for a 3.0 OMEGA
-
Which is wrong.
-
Which is wrong.
Al,to clarify, are you saying 2.6 or 3.2 cam covers, on a coil pack per bank setup, will fit the posters 2.5 omega with ht leads?
-
Yes.
Both have 3 plugs per bank in exactly the same place. All the hardware is in exactly the same place. Hell, even the gaskets are interchangeable. The DBW 3.0 is living proof of this.
-
Yes.

But there is no DBW 3.0 omega?
Therefore covers for a DBW omega/Cadillac, will not fit a 2.5/3.0 omega with a ht lead setup...

So the Catera is the Omega Bs imaginary friend then...
Ok, put it another way... are the plug wells on an early 2.5/3.0 head round?
-

Of course not , aside of the addition of the threads to secure coil packs on later heads, the plug setup on the heads themselves are identical?
But, by fitting individual ht leads to camcovers designed to take coil packs, they will not clip in correctly and risk poor connections and water ingress..

So what you're suggesting is that the ht leads aren't a positive fit on the plugs? But instead that they are held in position but the camcovers?
As for water ingress, any water in the plugwells would be evaporated off as steam as soon as the engine is warmed... assuming the scuttle was poorly sealed in the first place ::)

Look at post #11 - different part nos for cable and dbw cam covers. As said we are not a Catera forum - op has a 2.5 cable Omega, based in UK.
Can confirm though that gaskets from AGP were fitted by me to our 2.6 V6 (drivers bank) and genuine Vx to passenger bank last year and to date no issues.

I think that's the bottom line.
The parts are indeed different, and whilst a DBW cam cover will keep the oil in on a 2.5 engine, it's not the right part and IMO a bit of a bodge

Useful to know, as the AGP ones are a damn site cheaper :y
Thanks for the pointer btw, I read that earlier ::) Technically though, any 2.6/3.2camcover will fit any 2.5/3.0 head perfectly and be leak free. And the gaskets are equally interchangeable. :y

Apart from the very late omega DBW models, which use a single gasket instead of 2 separate ones per camcover ;D :y

A manufacturing quirk rather than a technical point... ::)

Most v6 cam cover gaskets are part number 90511451,
The later single gasket per bank on very late v6 models is part number 55351456
I've no idea why vx chose to do that so late on though
-
doesnt the double gasket have a joining rubber which acts as a seal to stop water or oil ingress?
-
Are we talking about this :-\ If so what year onwards does this go on :-\
