There is enough slop in the system that the chain dancing around damps the resonance energy via aerodynamic drag. "I'm good with that"That chain redrive is horrific. I'd be amazed if he hasn't broken his crank.
I suspect we won't have enough delta to run the stock pump. The only way we will know for sure is to build/test. Even if we see enough at ground level there may not be enough at altitude. Lots of these engines ran just fine before they started putting on this style of pump so I don't think it is going to be a significant problem.In my case, I will use the blowby to move the oil from the crank case to the oil tank and I don't know yet if the remaining vacuum is going to be enough for the fuel pump.
