leakdown results!!??
Just pulled the engine from my 82 SC, this winter for a tranny O/H.
Out of interest, did a leak down test as I thought the car was getting weaker over the last few months prior to storage.
A borrowed tester with no directions, but used 72 psi on the first gauge, got 74 on the second gauge. Cyl 456 all same results. Cyl 123 all leaked alot, seems to be head gasket area - can feel the air whistling out. Further investigation - found a head barrel nut on the #2 cyl just lying around under the valve cover. I've replaced all my studs last year with steel, studs are good, re rung the engine as well and it ran well. Everything was triple checked at assembly so why the loose nut? Can this cause all three cyls to leak at the head gasket? Elapsed mileage since last years work roughly 8000 miles.
Now, what can I expect when the heads come off???/ Other than more dough to spend.
