This car sat for 25 years on jack stands. I've been working on the brakes knowing I have some leakage from the valve covers but after running the engine for the last few weeks severe leaks developed that required some level of disassembly. I couldn't see well enough around the back of the engine to determine if I had a head gasket problem so I was prepared to remove the heads.
Don't want to if I don't have to at this time. Know what I mean?
