2001 , 4.3 , tbi, mercooler fuel pump, mefi 3.
2 reman, motors, first motor detonated # 3 piston (dime size hole) 40-60 hrs. 2nd motor , scoured #2, in 30 some hrs. Only thing I found was a lifter tick, and no oil to top of rocker arms. On number 2 cylinder on starboard side These are reman. motors.
Q if regulator on return side of cool pump goes bad, is it possible that tbi can over fuel, I'm setting timing with CDI software, in base mode.
I have recorded print out of what info I can get. Any info would be appreciated. THANKS
