Well guys, here’s the thing. Bought a Jensen Healey that was supposed to have 14k original miles, when it showed up (I know, don’t buy a car without seeing it in person(!)), I thought , hmmm looks like more than 14k to me. I decided to do a compression check before buying the many parts it looked like it needed. . . Compression test results 1- 170 2 - 75 3 - 40 4 - 150 From what I've read I thought this might be a head gasket issue, but I did a "wet compression test" on 2 and 3 - 2 - 120 3 - 60 Well, I have never done a compression check before, not having done much engine work either. Am I looking at learning a lot of engine work now? Maybe I should just sell it for a lot less than I paid for it? Suicide? Thanks for any help George

Could be rings. Or valves. Unfortunately you won't know for sure until you open it up. If you decide to keep it I say an engine rebuild is needed.

On the other side of the coiin...what we used to do with old cars is to get the durned thing running...use some thin oil instead of thick as you want to get things loosened up and then drain the oil and put in the correct oil and check it again. Often we found the rings were stuck and it just needed running to loosen it up. Another trick was to use a quart of transmission fluid to the oil in the crankcase, which loosened things up...we actually would run it fifty miles or so and it worked back then...maybe it is worth trying now before you dismantle the engine.....
