I put the cat back ontoday for the MOT and noticed quite a lot of oil leaking from around the crank case breather, it's not coming from the valve itself but further back before the hose, has anyone had this problem before?!

Cheers!!

 

i think this is where mine is leaking from aswell,would like to know the cause

 

Mine also. Think it must be a factory fitted leak lol

 

ive heard thats a common fault mate.my s2 been leaking for few weeks.got round to checkin it yesterday and the sump was being held on by just a couple of threads on each nut

 

It's weird, whilst I had the cat off I took the heat shield off the crank breather case, and it only seemed to be leaking near there the breather hose goes?! used a mirror but still couldn't really see it?! It's bugging me! I need to take a good look at it!

 

the tin sump hasnt rotted through near that area?
also check pcv valve and the mini oil catch tank to make sure its not full
there is a seal on the pcv vent at thr front of the block

 

Hey, Replaced the old sump a year or so ago and the valve, but will check the rubber grommet seal it sits in....i need 2 take a close look this weekend!! cheers dude

 

also check rocker cover gasket,
check oil return for the turbo not split

no probs m8ty
if slove problem lets us know
