JieM, that engine looks happy enough! Can you show us a pic of your MMM hub mounted. Anything to look out for when installing it?
Anyone have any idea what would happen to the oil distribution to the rockers in the negative pressure crankcase scenario? I know that the amount of oil getting to the top cylinder was marginal under normal circumstances, I wonder if it would be better with the negative pressure instance.
Sparky, I would put the MMM hub on there chap, regardless of how well your engine is running, if it is on std timing, then things are not happy under the hood.
