hello, worked on plenty of stuff, new to this flathead world. have a 1951 pickup with a flathead in it and a manual trans. have engine and trans out of it. Engine rotates, but compression was crap. I took heads off to find out that most valves were stuck.. soaked them for a week and now all but two open and close. I took one of the valves out to find out the lifter was collapsed. The second lifter is collapsed also. I am thinking of just taking the whole thing apart and doing a complete top end rebuild. Engine turns over freely by hand. I also have about a gallon of kerosene in the oil that I was using the crank the engine and let the oil pump bathe the valves and lifters to free them up. The transmission is stuck to the block. I got it about two inches apart and now it is not going any more. I am wondering if I just need a bigger prybar and should see where it goes. I do have the starter out, but the starter bracket is still in there. I would prefer to power wash all of these parts separately and paint them before reassembly. Have taken a couple manual transmissions from the engine and remember that they just separated once out. thanks for any info. knowing what the engine type and transmission type are would help me down the line I suppose.
