Title: Oil in spark plug ?????
Post by: Ady on 18 January 2014, 10:30:48

Just changing my spark plugs on a 2.6 and I have oil in no 5 spark plug.  :(

Any one know the cause if this? Car seems to drive ok wondering if it is a leaking rocker cover.

Cam cover gasket. Sadly it needs to be genuine part, as pattern ones will usually last somewhere between 1 week and 6 months.

Also clear out the breathers, which can also lead to premature gasket failure.

Ok thanks for the advice. Getting it booked in for cam belt soon so will get them to do the cam cover gasket at the same time.

Is it this part I need to replace?

Part No.: 369720071 Was £5.28
Now £3.24

Will get it from vauxhall when I do get it done but found this on euro car parts, just used them to see what part looked like.

The GM part is about £40 a side, plus the o-rings (8 a side).

No idea about part numbers from ECP, I don't ever use their crap.

Make sure the Cambelt is setup with the correct kit :y
