Thought i'd post here to see if anyone can pick up on something ive missed.

I rebuilt my s5 13bt & it was fine on 1st start, ran it up the street & back & all seemed fine.

I went away for a few weeks over xmas, Started it when I came back & it smoked badly... after some checking I removed the gate & found the exhaust manifold to be coated in oil. Pulled turbo manifold off & rear rotor has been blowing oil, a lot of oil.

So thinking about what has gone wrong I figured I probably have mixed up the assembled rotors & installed the front rotor as the rear etc. & hence oil control springs are on wrong sides & failing.


This engine I had the front & rear irons surface ground, new oem oil control ring casings & new oem oil control o-rings.

So I pulled the engine & stripped it tonight. Expecting to find oil control springs *** about. Nope. they are right & still in place in their notches. O-rings look fine.

So now im stumped. Any ideas?
