Leak oil sender unit 85 Toyota Truck 22R

Can I get and and replace the gasket or o-ring on the oil pressure sender unit? Does it even have one? Or do I have to buy a whole new oil pressure sender unit? Mine's leaking oil, don't want to drain the oil right now just to see if the thing has an o ring.


there is no o-ring. the sending unit just threads into the side of the block. word of caution- you may want to douse the old unit with some deep creep or something similar and let it work in there for a bit before attemping to remove it. i did not, and as of right now i have threads from a broken off oil pressure sending unit sticking out the side of my block.

Clean the area really well, then start it up and be sure that the unit is leaking from the threads before you try this. Usually the leak is in the unit itself, not the threaded connection to the block.

This is a common failure, most likely the sending unit is leaking. If the "threads" are leaking, then the problem would havebeen constant.

You can pick up a generic replacement for ~$10.

good luck! GTr
