Hello I wish help to solve my problem, I have a Kia Sportage Motor D439H904202 that was repaired in engine but the oil pressure is very low, I already change oil pump and I have no solution. which could be the possible failures. thank you.
Hi Jose, what are you llaaming for pressure? Some hot give the idle 0.8 bar or less, if uploading it to 4000 rpm it gives you less than 3 bar .... The same the pump discharge valve does not close well, also if you discard the above, it can be due to wear in crankshaft or connecting bulls; that if they have excessive game, they escape by losing pressure already, in the rest of the circuit. Greetings!!
