Ok. I already said that. IF you need oil at the lifters (like you are using pushrod oiling and such) and IF you have blocked the oil off at the number 1 main bearing, then you have to get oil to the drivers side somehow. I agree with that.
But doing that cross over to slow the oil don’t is just wrong.
I also said I was going to look at a different way to feed the rocker gear rather than up through the cam or pushrod oiling.
I just don’t have the time right now to bother with it but I think there is a better way to not rob any oil from the crank to lube the rocker gear.
