The last word on high volume oil pump for 7M's ?

[chevyeater]

Interesting info guys. Thanks But honestly it sounds like Chevy is getting the same pressure roughly that IJ is getting without the squirters. Now the question is, is the direct leak of oil pressure from the squirters that CJ refers to, a real issue or not?

I'm sure they have some effect on the oil pressure. Ian said his bottom end is on the loose side, mine is on the tight side and my machinist made some other adjustments to the oiling system as well. I'd probably have higher pressure than him if I'd blocked off the squirters. Decide if you are going to be needing them while you have the motor out (spending extended periods @ WOT/track sessions on a roadcourse?).

fwiw earily jdm 7mgte blocks don't have oil squirters, but have the oil feed/2nd knock sensor etc. I have been hesitant to build this block because of its lack of squirters, but perhaps it is not such a bad thing after all.
