Diesel or Oil Leak?

Unread post by joaocpereira »

Hello

I look at the motor today and saw this liquid around this area… is that oil or diesel? Any guess where look for a leak?

Probably engine oil. I had similar pools of oil and it came from the cam cover to cylinder head joint. I had it fixed at the same time I had the timing belt, tensioners, etc changed.

You don't say what engine you have fitted but it's a not uncommon fault with the 1.6 BlueHdi diesel engine.
As I get older I think a lot about the hereafter - I go into a room and then wonder what I'm here after.

Inside every old person is a young person wondering what the hell happened.

It's an 1.6 HDI.

Thank you for the info.
