Omega General Help / Omega 1999 2.5 v6-Rocket Cover/Gasket Replacement

« on: 18 November 2009, 11:25:19 »

Hi,

I have read a few times that the Rocker Covers on the Omega (1999 year or similar model) 2.5 v6 Petrol engine can be replaced with the alloy Vectra ones.

Does anyone have the existing Part Numbers for the Omega plastic ones and the Part Numbers required for the alloy vectra ones at all please ?

Also is it a straight forward swap over ?

I am getting a bit sick in having to keep having the plastic omega ones replaced, done 100K since getting the car and its currently in the garage as I type this being done for the 3rd time due to warping. It seems the rocker covers are taking it in turn to fail every 30K miles.

So next time I would like to get an alloy ones fitted and see how it lasts.

Cheers
Diddy

Omega General Help / Omega 2.5 v6 intermitant accelleration problem

« on: 16 July 2007, 08:43:06 »

Hello,

Got an anoying problem with my Omega, and before I speak with a garage would appreciate some thoughts plz

Car was serviced and MOTed 2 weeks ago and all was fine.

But today it started to struggle and lack power when accelerating around the 40 to 60mph mark when the revs are about 3K+

You will put your foot down whilst at speed and the car will drop a gear and then it will hesitate and seem to struggle to accellerate perhaps between the 3K to 5K mark then at 5K power will be delivered as normal.

Poodling about normally and not accellerating aggresively it seems fine.

If anyone can suggest potential cause for this I would be grateful

Cheers
Diddy

PS whilst not under load the car revs fine
