had an oil cleaner run threw motor, this did not do any good.also had replaced oil pump. am at my wits end with this truck !!
you extra suitable than probably have a undesirable oil pump inflicting this to take place whilst the relief valve is going undesirable or does not artwork actual it shall all of us the oil stress pass by ability of it,and that provides you with no oil stress one the engine is heat,you are able to ought to additionally examine the oil pan in this one and verify it does not have loads of sludge outfitted up in it,those have been undesirable to do this,and that could desire to supply up the oil sump up on them,and that too will reason you to unfastened oil stress as quickly because it warms up,solid good fortune on it.and happy thanksgiving.
ok so have you considerd the oil rings being worn? you didnt state if you did top end just crank and bearings so my thoughts are, that your top end is tired, you also didnt mention if it smoked at all, that would be an indication of worn rings. Just because you replaced your oil pump doesnt mean that you didnt get a faulty one, get a compression test done and that will let you know if it is rings.
oild pressure sending unit reads off one of the cam bearings and if the bearing is worn will cause a drop in oil pressure
you may have some blockage in the oil pump or have oil pump failure on it,i rebuilt a 360 a while back and cranked it up and never did get oil pressure,took it back out and found the oil pump wasn't working,i got lucky it didn't cost me an engine,but check the pump and also make sure it didn't spin a bearing on it,that will stop the oil pressure from building up,id pull it back out if i couldn't get no pressure,it has to be in a bearing or a pump or blockage somewhere,good luck.
so you replaced the oil pump, crank and bearings and still have no oil press. hot or cold? did you check the bearing clearances when you put it together? what were they? did you replace the cam bearings? doese it make any knocking noises? are you checking the pressure with a manual gauge or the one in the dash? the one in the dash is useless. now i see that i ansmwered your other question a few days ago. what did your bearings look like when you took them out? i also thought of one other thing. i have seen people somehow bolt the oil pump up without getting the driveshaft into the pump. you wouldn't have any pressure at all ever. do you have pressure cold?
