CURRENTLY GOT A STANDARD 2.6 OMEGA LOW MILAGE .. ITS HAVING NEW TAPPETS FITTED AND CAMBELT WATER PUMP KIT AS OF NEXT WEEK..
WANT TO KNOW IS IT WORTH CHANGING THE INLET CAMS WHILE ITS ALL APART TO G CAMS. HEARD IT CAN GIVE A GOOD 10-15BHP FITTING G INLET CAMS...
AS PER MSD VECS

A very worth while mod,as its in pieces be silly not,to add the cams, you also need the divider plate as well.
Ps turn caps lock off(capitals),its the same as shouting,and welcome :y
-
If it's a 2.6 I'd take the opportunity to go the whole hog and replace the valve stem seals.
-
Have a pair of G cams & sandwich plate here for sale ;)
-
whats this sandwhich plate for ??
and no need for valve stem oil seals as car is fine only done 71k and no even a hint of smoke ...
-
Sandwich plate sits between inlet manifold and heads...
As for stem seals... Do them now, whilst the heads are being sorted as they will fail soon enough if left ;)
-
never had any valve stem seals fail on a v6 omega ??
is it common to just 2.6 if so why as wouldn't they be same as 3.2??
so you can change cams without sandwhich plate then as im guessing you swap it for bigger opening as per a 3.0. but unless head ported you now have a step which is worse than original.
-
The head on mine was ported when the 3 litre cams were put in, put on rolling road and threw out 195bhp, so increase of 16bhp, and that was a a hole in the exhaust, now charged to stainless steel cats back, but have yet to put it back on rolling road.

Stem seal failure is a 2.6 issue...

Vauxhall in there wisdom decided to penny pinch for a couple of years and fitted cheap seals to the 2.6.
I cant remember which years though :-\
You will still get the extra bhp without the porting but if you know how the port, it will smooth out the airflow a little more and help driveability :y
-
Wasn't it 2001-2002 :-\
-
From memory, its was early 2.6's that had the valve stem seal problem, so yes, 2001/2
-
Apart from I have a very late 2003 2.6 that suffered with the valve stem seal issues.

Well that pretty much covers all the 2.6s then... :D
-
If your going to fit G Cams to inlet, also worth changing the Exhaust to A Cams as well, fairly sure there J's on a 2.6.

For the sake of a few quids worth of seals it's well worth changing them while the rockers are off Laney
