hey guys i have a 300e 86 model and my spark plugs keep getting covered in oil instantly and also i have drops of oil coming out of the exhaust.is this a valve stem seal problem or something else?

my mechanic said $3000AU to do a top end rebuild which would apparently fix this problem is this necessary?

regards
Kris

 

It could be valve guide seals. That is somewhat common on the M103 engine.

 

is that the same as valve stem seals?? sorry don't no much about engines

 

YEAH ITS THE SAME....JUST HAVE HIM REPLACE THE VALVE SEALS he shouldnt have to rebuild the whole head..AND IF HE TAKES THE HEAD OFF TO DO IT THEN HAVE IM REPLACE THE HEADGASKET AS WELL...Good Luck!
