Oil leak at front of camshaft
Posted: Tue Aug 08, 2023 6:53 pm
This CY engine isn't very old but I don't know who built it.
Oil has been leaking out of the top since I first started it.
I thought it was the valve cover, then the head gasket, but
finally last night I had cleaned it up and did a short trip,
and was lucky to see it through the cam sprocket with a mirror right
on the middle of the cam seal.
Small black stream running down the bottom of the cam front seal.
It even keeps leaking for a few minutes AFTER the engine is shut off.
I probably ruined my valve cover gasket thinking that was it, overtightening,
but a new one is coming tomorrrow.
I'm thinking maybe the #1 cam cap doesn't have any sealant or the cam seal was installed wrong.
What's the correct way to do this? Remove the cap and give it a little hylomar spray?
Not much covering this topic.
Seems like the easiest thing to try first.
I see the torque is pretty low on those caps, and I better not put on backwards.
Also wondering if this has had an effect on my oil pressure.
