did you check your piston rings for end gap? wondering if they are what scored the cylinder wall.
Yes every ring I paired to each cylinder and was checked squared and filed accordingly. I was very thorough and meticulous, at least I think I was ha. Aside from my moment of retardation with lubing the pistons and cylinders.
There is a whole lot of armchair quarterbacking going on here from people that cannot see the engine in person and that had no hand in the assembly. The reason I say this is because there are more reasons given for the demise of this engine than I have ever seen but I have yet to see any solid exact to the thousandth measurements. I am not trying to be a smart ass but nobody is going to be able to diagnose the problem online, myself included. We can surmise but that is just a fancy word for "Guess". Have you had any correspondence with the machinist and what has he said? You need to take everything to him and have him look it over and he can tell you exactly what happened. If he is an honest guy he will own up to a mistake he made. I have seen it happen many times. Not all machinists are crooked.
i have been lurking on this this thread, i really have a few questions.
whats the set up on the build?
got pics of the rod bearings?
thats 20 miles on those heads? those chambers are dirty.
what did you torque the head studs too?
was that the correct piston to bore clearance?
did you miss the tune up?
