Oil pump test plugs

Featured Replies

Hey guys, just wondering do they sometimes leak?? I see oil coming out of one, but it might just be my oil pump itself leaking down doesn't seem like it though. Any ideas don't feel like pulling the belt and replacing the gaskets till spring.

You know those two huge allen key plugs when you look at the bottom of the engine that are part of the oil pump?

probably the oil pump shaft seal is leaking

What year and how many miles on this car. When was the last time a timing belt was done and cam/main seals?

Those allens don't leak. And they are usually TIGHT! But I really don't know what purpose they serve.

 

Nipper has the correct questions. ALong with if the pump was ever off did they check the phillips screws to make sure they were tight and use an OEM crank seal.

depending on if you have an analog gauge, or a dummy lite, one or the other of the plugs is used depending on the sending unit.
