Oil leak from head - what all can leak?

[Cox Abele]

I've seen a little bit of oil leaking from my 2g 4g63 cylinder head. It is a remanufactured unit with no cracks or anything like that. The head gasket isn't leaking either, so no worries there. I know the valve cover gasket had a small leak and I'm getting ready to replace it once I finish posting this thread.

I know this head has an oiling port for the turbo. I'm running my oiling from the filter housing. The port has an allen plug in it which I'll remove to put a little thread sealant on. This is most likely the source of my leak, but while I'm in there, I'd like to know if there are other ports like the turbo feed that I could be having issues with.

The top center exhaust manifold stud has an oil passage behind it, RTV that stud before installing your exhaust manifold.

Also if your oil cap leaks it can run into the spark plug valley and drain out of a small hole near the power steering pump.

haven't had any issues from the exhaust stud or oil cap. I'm fairly certain I've found the source of my leak being the oil feed lines. It wasn't bad, but I didn't want to see oil leaking. There was only a drop or two.
