Need some opinions. I've noticed oil in the coolant of my '72 TR6, and here's what I know. The leak into the coolant is not horrible but it's definitely there. Have done some very preliminary checks, like a dry compression (forgot to open throttle, oops) and I'm getting ~120 psi at cylinders 2-6, and 140psi at #1. Plugs on cylinders and 2-6 look good, but #1 looks black.
Also, I realize that the radiator cap is rated at 13psi, and it's supposed to be 7. That will be replaced.
How I should continue to scope this out? Hoping for not a head gasket replacement, but the big difference at #1 is concerning. Thanks.
