Q: Either the oil pump or oil sending unit is going bad. I don't know which one.

asked by on January 23, 2017

Since I bought my truck it has had low oil pressure. Now even when i'm at 3,000 rpm it will just zero out. I DO have oil in the truck but with the pressure at zero most of the time my lifters are really getting loud. I'm not sure which it is so I can fix it.

My car has 157000 miles.
My car has an automatic transmission.
