HPOP oil pressure vs. LPOP oil pressure...
'05 F250 6.0 PSD:
1) Is the oil pressure gauge on dash monitoring lubrication circuit's oil pressure (LPOP), or is it monitoring fuel system's oil pressure (HPOP)?
2) Is "LOW OIL PRESSURE" warning all about lubrication circuit, or is it about high pressure circuit, or maybe either?
3) Is it possible for IPR to fail due to a very simple problem like easy removing dirt or not so important foreign object?
Does it woth it (in applicable cases) to try to fix a stucked IPR only by cleaning the part or removing some not catastrophic obstruction, or every time it gets stuck means replacing the part? (It is not cheap).
How bad or agressive does an obstruction needs to be in order to damage IPR's integrity?
Can the solenoid coil be damaged (overheat, open circuit) when an obstruction doesn't let the valve section move?
All hypothetical scenarios, just sharping my 365VGT knowledge, Thanks for sharing yours!
