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.

OK thanks. deep creep is like WD-40? I wonder if it's leaking oil if
the threads aren't already oiled. Sounds like this could be a cheap
fix, remove the oil pressure unit, wrapp some teflon tape around the
threads and reinsert. What do you think?

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.

Every day is a good day- it's just that some are better than others.

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!
