Hi there,
just put my engine in some of you may have seen in my project thread. i took a perfect working 43k 172 cup engine, i drove the car i know the engine was good.
Took it out the car and did some "work" to it over the winter, it hasnt been started in a good 7-8 months. In that time i took the head apart completely bought new valves lapped them in and rebuilt it up.
When cranking it you can hear it "misses" on one of the cylinders so i compression checked it.
Cyls 1, 2 and 3 were all exactly the same 170psi.
However cylinder 4 was 0psi!, crankingi it with the tester in just made it sound like there was nothing in the spark plug hole...
Infuriated i ripped the engine apart, to reveal abssolutely nothing out of the ordinary, all bores and pistons looked perfect just as they did when i assembled the engine.
I put the cams in with the head off the engine and rotated them all valves open as they should.
I tested for leakage (allbeit with water and not diesel as i didnt have any), and there was not a smidgen of leakage past the valves.
Wat do?
