Today I had a look at the plugs and sure enough plug No 3 was full of oil! Ive cleaned it out but the car still misfires,
How much will it cost to have the cam cover gaskets replaced and is it worth having the head gaskts replaced at the same time?? :-/
Cam cover gaskets are not too bad to replace. Probably about 3-4 hours the first time.
If taking to a garage ( :-/) make sure they know what 8nm is!! This is the torque setting of the cam covers. Tighten much more than this and you crush the gaskets causing leaks... again!
Also, as said before. The breather system MUST be cleaned thoroughly as the blockages in this cause the leakage.
As for changing head gaskets?
Err, I really would not recommend it unless you feel you have far too much money and wish to dispose of a large sum of it for no good reason!
Nothing wrong with the heads by the sound of it.
You may well need a replacement DIS pack though... (approx £80 off ebay, more from dealer!)
