High pressure oil readings...are these normal??
I've been tracking down what feels like a stutter or skipping with loss of power. Yesterday I put together an assembly to read the high pressure oil pressure at the cylinder heads by removing the brass plug and attaching the hose and gauge assembly. The gauge is a liquid filled one that reads o-6000 psi so getting an EXACT reading was tough but I'd say within +/- 20 psi.
So, I was reading the following:
Idle: 620 psi
1000 rpm: 650 psi
1500 rpm: 800 psi
2000 rpm: 1050 psi
2500 rpm: 1250 psi
3000 rpm: 1420 psi
I did not ram it to governor (WOT). Are these numbers reasonable or "as expected"? My understanding is that at minimum the injectors require ~400 psi to open, and I am well above that even at idle.
Interested to see if these numbers are realistic...
Thanks, in advance, for any feedback!!!
