I just put a new head on my 01 XJ since i bought it with a cracked head. The girl i bought it from said it ran fine before it started overheating. she's a nice girl and i know her, so i don't think she's lying to me.
so when i start it up cold i'm over 40 psi of oil pressure, once it warms up though i'm only at about 15-20 psi cruising and it'll drop to 10, and then sometimes 0 at stop lights.
I don't hear any valvetrain noise. no knocking or anything even when left idling at an indicated 0 psi oil pressure. I had 10/30 synthetic and i changed it over to 20/50 just to see if it would be better and there's no change.
i replaced the sending unit (sensor by the oil filter) but no change. All i did was unscrew the old one and screw in the new one. Someone mentioned cleaning out the hole but i don't think that's the issue.
I'm going to double check with a mechanical gauge and if i see no oil pressure i was going to pull the pan and check the bearings and if they're not down to brass, replace the oil pump.
I was wondering if there's a typical issue that causes this. Is there anything i should be looking for or is this just a powertech motor and i should probably just start motor shopping?
Thanks guys
