I am in the process of replacing my oil pump on my d15b8 engine. I have bought two different oil pumps now both with the same result, When i put the oil pump on the block, one side of it sticks up about 2-3 mm above the flat surface where the oil pan sits on. Has anyone else had this problem. What am I supposed to do? The old one fits on there perfect with no problem.

 

Get the right oil pump? It sounds like you're buying the wrong replacement pumps.

 

What is the engine type stamped on the block.

 

d15b8 i know what my engine is. But the pumps all say they work with d15b8 but both of them fit its just the one side that is raised too much.
