Spyder Oil leak from under intake manifold

[Michael Palmer]

I have a leak under my intake manifold. My instructor told me it may be a bolt near the balance shaft. Can you confirm if this is a common issue?

is your valve cover leaking? i'm gonna guess and say yes. Those valve covers suck to seal. The thing is made of 2 pieces of thin sheet metal formed in a press instead of cast like on the other engines.
If it was my car i would just pull the valve cover and the intake manifold. Clean the inside of the manifold, re install it with a new gasket, put a new valve cover gasket on and change the PCV valve.

Mitsubishi designed metal valve covers suck in the first place but then people don’t know what a torque spec is and they warp them making them even more fun. Do you have pics?

No it is not common. Possible yes but not probable. Somebody would've had to leave it loose.

It turned out to be that bolt. It was not replaced during the initial rebuild

I saw a little oil on my intake manifold (4g63) so while I was getting my flywheel resurfaced, I had him check the intake manifold. First pic is .001” removed, then another .001” and a final pass to get it flush.
