IMPORTANT: The Chronicles of Low Oil Pressure by 07burb

[DSRBLDR47]

Just to be clear, you can't change the oil pump by dropping the pan when changing the o-ring and pan gasket, correct? Its on the front and not easy to change? Would low/no oil pressure allow the DOD lifters to collapse by dropping those four cylinders causing a power loss in the process?

Here's a great video about LS cam bearings, low/no oil pressure, and etc:

AFM lifters need a minimum of 22 or 27 psi to collapse the pins. So, no, if the oil pressure is too low AFM won't work.

Thanks Don, learned a bunch today from that video! It answered several lingering questions.
