Purchased in Hawaii in 2009, our split window coupe has a 327 fuel injected engine and the very rare Heater Delete option. Our Corvette was restored over a 4 year period using original 1963 components. Modifications were limited to those popular in the late 1960's. Our vision... Period Correct/Era Modified.

327 - The Oil Leak, Up close and Personal
First of all I'd like to thank Ausy Pete for coming up with a possible solution to fix our oil leak without removing the head. I tried it but unfortunately it didn't work. The plug was just too deep. It was a great recommendation though. As you'll recall this is where we suspected our oil leak was located. I spun the oil pump again and sure enough this is it, an oil galley plug. This will require major dis-assembly of our 327. Double click on the following pictures to see the details.
I used plastic wire ties to hold the push rods in place. This head is coming off then going right back on within a day or two.
Look at the size of these valves.
I don't know about you but this is just about the prettiest set of pistons I've seen in awhile.
And here's the culprit. It was only installed tool tight, nothing near the recommended 20 ft pounds. I'll clean up the threads then apply a small amount of Permatex Ultra-Blue (a high temperature oil resistant silicone), torque, then start the reassembly process. A nice set of Fel-Pro gaskets has already been purchased so we are ready to reassemble.
