Re: Noisy Lifters even though they are new

Update:

I ran the engine (idling) for more than 1 hour and 15 minutes.

After ~30 minutes I noticed the oil pressure (at idle) was dropping below 40.

By the end of 1 hour and 15 minutes the oil pressure at idle had dropped down to ~ 10 psi, though it rose quickly to 40 if I applied a bit of throttle. The little red light had yet to flicker. However, I ran out of time to find out at what oil pressure the light begins to flicker. Probably as was noted earlier b/t 5 and 10 psi.

Lifter began to slightly tick at about the same time as the oil pressure began to drop below 40, and the tick got louder as the oil pressure dropped.

May try again later for more data.
