With Meling 296hv pump..

No, 40 hot @ 1800 /2000 rpm with 5w30 m1 is the best I got..

I just switched to Rotalla 15w40. Helped a little on pressure. My only problem is sitting at a red light and my pressue is about 2/4. 195k on engine. Thinking of meling 296 hv oil pump, seems to help the idle issue. I have a new meling 295 pump now, didn’t help much over stock pump.

New o ring, new oil pump, new sender unit. No noise, just low pressure at idle. Driving I have 20/30 1500 to 1800 rpm.

Same issue on my 04 5.3. I was told rod bearing won't help the low pressure @ 500 rpm. I'm thinking rod and main bearings, I don't have any more ideas.

I have a 04 that does the same thing. Idle hot 500 rpm and gage drops to about 10 psi, touch the gas and goes to 20. Only thing left to replace is rod bearing.. No noises, Hot or Cold, I'm stumped. Any ideas out there..??
