Thanks Guys for all the replys. The "mechanic" warmed up the engine and checked the compression on the first four cylinders 4# was 150lbs, 3# was 150 lbs, 2# was zero compression it tried to build up and instantly leaked down to zero, 1#was 150 lbs. The engine does not make any funky sounds except for the misfiring on two cylinders number 2 and 7 when he pulled the wires from the distributor they sparked at the distributor but the engine did not run any smoother just not firing on two cylinders. He only tested the cylinders on one side but said no need to test any farther the engine needed a valve job. I paid him $35. dollars he said he would deduct it from the valve job. Again what do you guys think? Is his diagnosis accurate?
