I bought FUELGEDDES' LX-450. (https://forum.ih8mud.com/showthread.php?t=121735) Last night, I connected a mechanical oil pressure gage and here are my findings: At startup, the pressure is about 60-65 psi After one minute, it drops to around 40 psi After about five minutes (engine is starting to warm), the pressure is 20 psi. After a few more minutes (engine is fully warm), the pressure drops to zero. Once the pressure drops, I have noticed that the oil pressure doesn't change much as you increase the throttle. I checked the oil level with the dipstick after the pressure dropped to zero. The oil level was normal. The power steering assist seems OK. Any recommendations on where to go from here?
