M40 Oil leak

[AndyTouring]

My previously oil-tight 316 has suddenly started to leak oil in a fairly serious manner.

As far as I can see, there's a bit of a puddle forming under the inlet manifold & it's making it's way down the front of the engine. Don't think it's coming from the oil filter though it did have an oil change at the end of July.

Any ideas?

check ya rocker cover bolts are nice and tight and check the oil filter housing

They all seem ok. Thought it might be a hose under the inlet manifold.

Given it a good gunking so I'll see.

Cheers

Was the ring gasket on the oil filter container renewed?
If so then that's probably your trouble. First time i changed mine it pissed out everywhere so i don't change it anymore.
