Hi all,

just trying to service swmbo's 540, and have changed the oil filter, but every time we turn the engine over, it starts leaking from the top of the housing - it's like it's not returning oil to the engine. I've taken the housing off, and one of the unions does seem to be blocked (the old filter came apart when I took it out ) there also seems to be the bottom of the old filter stuck on the bottom of the housing - Any of you know which union is fill and which is return? One's marked R and the other's marked V, but German's not my strong point...

Any hints / tips?

Cheers


Vince

Found it - the old O ring on the housing cover looked just like a part of the cover - they're both black, and the O ring was squashed flat (it was leaking before I serviced it). Levered it off, replaced it with the new one, bolted it all back up, job's a goodun.

Cheers
