Question about 1989 Toyota Corolla 2 Door
A newly overhauled toyota 2e engine has a very low engine oil pressure,the oil pump has been replaced with a new one,still the problem exist,what seems to be the problem?
The only positive way to check if the oil pump is working and therefore there is correct oil pressure is to temporary install a non-electrical oil pressure gauge that uses a small copper tubing to sample the oil/pressure and drive a needle on the gauge. Depending on temperature, idle should register about 20+psi. Having done this and confirmed that indeed there is sufficient oil pressure then it may simply be a defective oil sending unit. Otherwise, no or low oil pressure at idle is an indicator that the engine needs to be opened up again.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
Good luck and kind regards.
Thank you for using FixYa.
