As some of you already know, the pressure dropped on DT last week the day after the dyno run and while my idiot light was on, a knock was heard. :: This knock also went away immediately when a little RPM was given to the motor and the idiot light went out. ::
So today I dropped the pan to swap pumps and visually inspect the motor. I didn't see any blueing on the rods, there was no pile of rubble in the oil pan and the bearings passed visual muster.
Immediately after dropping the pan, I found what the problem was causeing the low pressure state at idle.

There were several LARGE chunks of RTV in the pan that evidently squeezed out when the pan was mounted and plunked down into the pan
and some of these peices of RTV got sucked up into the pick up and were partially clogging the screen resulting in a diminished oil flow, especially prevalant at idle.....sound like a good theory?
Anyway....after mounting the new pump and doing some visual inspections that Randy (bosssman) insisted on, I put it back together and fired it up on the jack stands and could not hear a knocking sound coming from the motor. But I will not call it done yet....tommorrow I will put the steering back together, re-install the cross member and back it out of the garage where the sound of the mufflers and other standard motor noise won't be quite so loud and check for the knocking.
Cross your fingers for me.
