ot but ford

[ericlb]

2 of my friends are having a argument over a 1951 ford coupe, its a trade deal, and the car belonged to ones grandfather, who bought it new he's been around the car his whole life, and his grandfather rarely drove it, as farmers instead their pickup truck was the preferred vehicle for use, the car has 25ooo miles and runs and drives the friend who has it now is claiming the engine is worn out with only 60 psi of compression, 226 flathead, i told him at 60 psi the engine wouldnt even start, he needs to verify with a different gauge, and in any case the car has been sitting for over 10 years, it probably will improve if it was just driven and let the engine get seated back in opinions, hobo?

A simple ATF treatment will likely fix any compression problems if it is sticking rings

Although 60 psi isn't a lot when I went to school they said 40 psi was the minimum for a 4 stroke engine to run and 90 for a two stroke. If that is true then it would be possible that the engine will run. I did see a 350 Chevrolet engine that only had around 60 psi and it ran....but not very well. His gauge may be off or the rings could be stuck from sitting. It should have around 110 psi anyway.

Also if checking compression with only 1 plug removed, the throttle must be open to read true compression.
With the carb closed to idle position, compression will read about 1/2 the actual pressure generated with the throttle open.
