Oil Leak with pics.

When I was going over everything today I looked around in my engine bay and saw that my engine looked a little oily. I have to add oil every now and then, and I was reading that its normal for a 330 to burn a little. But this looks like its leaking pretty bad.


Vanos oil line do you guys think?

I wasn't too sure on the valve cover if it was or not. Might not hurt to do it anyway

Looks like a slow leak.

If you have to add oil its most likely not leaking from there

Check Oil filter housing gasket area and your crankcase ventilation valve area.

Euro604, are those 2 vertical cracks on the valve cover to the right of that mounting nut?
