Prior owner installed a 390hp Mopar crate 360. According to him he change to a bigger roller cam and roller rockers. I assume this was done years ago when the engine was installed. I can see orange or bronze looking rocker arms from the oil fill cap. She sounds like a big cam. He spent money and time on the car but he clearly wasn't a engine or car guy. So I question if these were changed out correctly.
With fresh 5w40 synthetic oil on a cold engine 65 degree day. I get 75psi at idle. As it warmed up on a drive it held 50psi and increased with rpm. Once warmed up at idle near 20psi. In gear and loping around 850rpm the gauge would read near zero. Slight bump in throttle and PSI jumps back up to 20-25. Put it in Neutral rpm are up and PSI is back to 20-25
These are some off brand gauges and the Optima battery is now 11 years old so when its gear at low rpm the volt meter is bouncing and the lights flicker as the electric fan is pulling power. I know that volts can cause irregular meter readings on some gauges. Could the cheap gauges and/or low battery volts be throwing out the very low oil pressure reading? This is my best hope.
The PCV is stopped up or something because she is pushing oil out the filler plug and PCV on the passenger side and crankcase filter on the drivers side. I plan on getting the adjustable PCV valve.
Zero smoke on start up. Zero smoke when driving. I pulled a oil sample at this oil change to see whats the oil like.
What is my best case and worse case scenario?
