I have a recently acquired an M170 (M38a1 variant) with this engine and would like to get an idea of where it is at health wise.
Compression going from #1->#4 cyl is 100, 100, 105, 115.
Surfing the web, I've found a pretty wide range of numbers for what an F-134 should be. One reference said 90-110lbs, another simply 135lbs. Perhaps the variation is due to the high and low altitude civilian heads and whatever the military used. There is a lot I want to do to and with this jeep. I'm just wanting to get an idea of how far out a rebuild is so I know where and when to focus energy and $$.
Thanks, Doug
