I guess I forgot to write that it is the exhaust valve that is leaking. All the pressure loss is coming out the tailpipe. I drove to the Kiawah Island Concourse a couple weeks ago with a double to triple does of Techron as a long shot to fix it but got no change. Hopefully I can tear the heads off in a few months.

Wow you finally got to the bottom of it ? Time to pull the heads I guess

What about a broken valve spring and it is not seating properly
