51 willys compression check

Hey guys, Im going to look at a 51 after work and need to know what kind of compression i should have on the motor? Thanks in advance.

 

F-134, 120-130psi

 

A '51 would be an L-head, wouldn't it? Didn't the F-heads come out in '54?

I could be wrong, wouldn't be the first time.

 

The F-134 came out in 50.

Edit:Jim never did mention what engine he was asking about, but the L-head ran from 41-53. If you look below my 50 & 51 have the F-134.

 

My service manual shows 100 psi for the L-head and 120-130 psi for the F-head. Nickmil.

 

Thanks guys, The jeep wasnt worth the money the guy was asking for it. I sure would have liked to have the warn winch he had on it. I really wanted to buy a flat fender anyways. Thanks again.

 

It was a military model and had the same fenders as my 1970. I dont know much about the early models. The man that owned it said it was a 1951.

 

Yes it was a F-Head.

 

It must have been an m38a1, and couldnt be older than 52 then
