Im impressed that the other three are so tight! Great job on that -- even on a high perf motor getting <3 % leakdown is darn good! How much time did you spend lapping the valves?
My gauge set is only so accurate so take 0% with a grain of salt. Also recall this was a hot test. Bottom line is they were consistent and looked "very low leakage". I did not do the valve job, I took the head to Precision Auto in Simsbury CT. It was not a fancy valve job.

Rus, just drive the thing, thats what you need to do. Revisit in a year if you want but start putting some miles on her.

Pete the miles are coming either way. It's practically been my daily in all but rainy weather. Plan on continuing that til the salt.

Generally, there is no such thing as magic in a bottle.

Running too rich to the point you’re washing the oil off the cylinder walls can lead to cylinder, piston, and ring damage. I had a leaking float wipe out a pair of cylinders in my 2300.

Electronic borescopes are pretty cheap these days. If you’ve lost a circlip, you might be able to intervene before there’s much damage. I’m NOT saying your symptoms are a certain sign of a displaced circlip. Just that checking with a borescope might spare you some serious heartache.

Rus, thanks for the link to your thread. We all like (good) things which remain a constant in a world of change and seeing Andrew and Mr. Peterson commenting reminds me that I/we have been talking here for .... twenty years? Fifteen at a minimum.

I see a borescope in your future.

BTW .... Rotella never went black in my old GTV. I use 15W/50 M-1 from Walmart in my air-cooled six but Rotella would likely be fine there, too.
