Do any oil lines run behind the head? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I have an oil leak problem.

It's dripping down off the bellhousing, but it seems to start from up above it.

I did the best I could with a flashlight and saw the top of the transmission and firewall behind the head had oil on it, so my hypothesis is that it's coming from back there.

Are there any oil lines that run behind the head? I'm thinking I'll have to pull the motor in order to fix this problem.

i had the same thing and suspected the RMS (after looking from underneath), but it was only the back of the valve cover.

theres no oil lines there

Maybe it's coming from your valve cover.

Yeah thats a valve cover leak. You may have to pull the engine for that though like you thought.

Sorry I didn't specify what engine.

It's a S13 SR20DET, but you guys were correct.

This was right behind the intake cam. It was bent inwards, guess I did a sucky job of installing and will be ordering ANOTHER one from West Co. next week.

I did pull on the engine to make myself feel better though.
