Oil leak cylinder head, help needed. (Solved).

Post by **Davez29** » Mon Apr 03, 2017 7:20 pm

Hi, I appear to have an oil leak going on, its coming out of the hole in the side of the cylinder head, below is a picture showing the hole in a similar engine. When my bike was working It didnt appear to have any problems or using oil, so dont know whats going on. Can anyone enlighten me whats going on and what that hole is for?

EDIT: Its ok, I just realised these are drain holes for the spark plugs and I had a pretty grotty cam cover gasket that must have been leaking. Just changed it today funny enough..

lesson learned

Easy fix and good to know what the holes are there for

Yes, i noticed it when i was renewing the gasket as the old one was like charcoal in places. I think i had a vague idea it was something like a drain hole but had to look around to be sure just in case i was wrong.
