Oil Leak Onto Turbo

[scotty nm35]

I was changing plugs and oil today, not too difficult, untill I found plug 6 full of oil, seeping from the rocker cover.

So off comes the intake plenum, plugs and wires everywhere. Got the cover off and I cant find anything wrong. I know there has been a drip onto the turbo occasionally, but the plug hole was full to the brim, there must be something wrong. Anyone else seen this one?

I used a sealant on everything and got it all together, now the engine light is on, probably from disconecting the throttle body? The car seems to drive ok with no obvious leaks.

Hopefully the tuner can organise a reset for me on tuesday when the emanage goes in.

Don't stress about the engine light.

It will "re-learn" and the light will go off in time.

Does it still stutter high in the rev range?

Didnt give it a bootfull, I will wait for the ecu to learn and check it in the arvo. The idle seemed fine.

I might need a new rocker cover if the leak returns.

so where is the leak exactly? did you manage to take any pics??

Sorry, the missus wont let me near the camera when Im that dirty.

I cant find any leak, but the rear plug on the passenger side was swimming in oil, this was then running down the rocker cover, dripping onto the turbo ex manifold. Very slow leak but over time filled the hole.

I cant see how the seal around the plug tube is removed, are there any pictures in fast?

Hi Scott

I came across this info today about the rocker cover seals leaking into the spark plug wells. Thought this sounded like your problem.

Yep. That would be it.

Sounds like a VQ issue.

I put anerobic gasket sealent around the seal and tube, should do the job. Im not spending the $300 or more. We should all check the plugs, this problem will be worse on m35 due to the turbo heat.
