Clinebarger, what do you think about the oil pump and the oil in the lower end? I also read that the AFM engine oil pump moves 20% more volume and when the engine is not in AFM mode, it pumps excess oil all over the piston skirts. I saw one thing saying to swap the pump and block the passage. My brother did not change the pump and he installed some kind of diverter that sends the excess oil right back into the pan.
Sorry, OP if I'm hijacking your thread.
It usually depends on what the customer wants to do.....I recommend installing a Standard Volume LS6 oil pump along with plugging the AFM relief valve in the pan. You will need a M14-1.5 shouldered plug.
The AFM relief valve is what sprays down #7 & #8 with oil......GM came out with a shield to help with the issue, Not sure if your truck had the shield installed or not?.....It would have been because of abnormal oil consumption under warranty.
If you do decide to swap the oil pump.....A camshaft upgrade is so easy to do at that point!
Check this out....Works with stock valve springs & DOES NOT require a tune!
