... on a warmed-up open-throttle plugless engine. And besides being a daily driver with no oil loss, according to MacCartney these engines shouldn't work with a compression less than 100 PSI!

After a squirt of oil into the combust' chamber, pressures are 150, 95, 80, 150.

-leaking valves, leaking bores?

-Guess I'm looking at both a head and block rebuild.

-I'm thinking about just a head rebuild but am I wasting my time?


TIA
