I wonder whether a chain slipping through the oil would really foam it up that badly. The oil in the rotors certainly get churned into a foamy state. The old connection rod splash rod would really foam the oil as it "beat" the oil several hundred times a minute - but I'll bet if anything the chain will just created a small turbulent area around it but not wide spread as it smoothly slips through the oil. Just speculation, of course, never seen a chain running through oil.

Given that it true - are you concerned that the chain will churn-up oil into foam?

Hi George,

Yep, that would be my concern. I figure if the Renesis really does run the oil an inch above the pan like Tracy once stated, and if the oil sprocket/chain is essentially the same, then there should be no problem running the oil that high. Obviously it would be better not to, but it's one of those compromises I may have to make.
