1994 Dodge Ram 1500 Base 8 Cyl 5.20L
How do you test if your oil pump is going bad or if it is just the guage?
I own a 1994 dodge ram 1500 with the 318 in it. I had just finished replacing the front wheel bearings and I took it for a spin. I notices the oil pressure gauge would suddenly drop and then go back up randomly. Is my pump going bad? Is the screen clogged? Or is my gauge just going out?
The best way to test is a mechanical gauge that is placed into the block. The gauge will be available at your local parts store or tool store, and treads into the oil pressure sending unit's place. This will tell you the actual oil pressure reading of the engine. Diagnose from there as to whether or not you have an engine or electrical issue.
