Hi all, 2 weeks ago my car started feeling different. It then went on to produce clouds of smoke (white when cold and blue when warm). The car stinks of oil in the cab when stopped.
I had to change spark 4 plug due to it starting to misfire and also changed to HFC.
I'm thinking that it could be valve stem oil seals that have gone. Is this a common problem with 350z at 100k miles?
Any other ideas??
I can't find any how to's on how to remove both heads or anything about valve stem seals going so I'm thinking maybe it's another issue.
If it was a head gasket I'd see residue on the cap but that is clean and the oil I drained out is still good.
Any help welcome. This is on a 2004 DE uk car
