318 - intake vacuum leaking

418BCC36-DD14-4CE9-B92C-278E7483877A.jpeg UPDATE: pulled the intake- found 5 loose bolts- finger tight. Pulled intake off and almost all intake valves have a glossy oil coat but runners in head AND intake are clean.
The end gaskets were crushed paper thin -cork and started out almost 1/4” thick.
The fel-pro gaskets were thinner in the middle of the ports than they were at the ends. But solid seals.
I pulled the plugs and there were 3 heavily crusted in burnt oil 5 were like what you would find in a new car... slight tan. No build up. 100
Miles today on them.

I found my compression gauge was wrong- used my back up and 5 good cylinders are like 175-177psi.
The 3 burnt oil spark plug cylinders were 150-155psi. I think I am going to reinstall the intake with new gaskets. Tighten all down and install new spark plugs and change the oil and run it and see if it improves. If it does not- sadly I will go from there.
