As if, as if I dont know.


It isn't your fault; they are extremely sensitive engines. Both with respect to the spaces between parts, and the filthy air we breath. You should be building this engine in a clean room with a running HEPA filter, as if you are painting a car. And that is assuming you can actually get decent machine work done to it; which I want to say is the primary cause for failure to begin with. Something the owner has no control over, isn't that just perfect? You can be the best engine builder in the world and have it fall apart because the guy in the machine shop doesn't specialize in tight engines, and thinks that .0022" is close enough to .0014" for it to work.

Ill add you to the list I recently started keeping track

Sadly I do think he is partly right... A lot of SR's seem to fail shortly after being rebuilt, and I have read a few post from a few notable engine builders on other SR forums about how they can be extremely finicky when getting rebuilt. I just have confidence that as long as my tolerances are checked, double checked, plastigauged for lolz, then remeasured yet again, mine will stay together.

OP, do you have any measurements from your rebuild? I would like to know what failed and possibly why.. Maybe tolerances were a little too off?
