WANTED - Oil Pressure Sending Unit
« on: May 20, 2014, 09:38:18 PM »
The oil pressure sending unit in my 53 has seen better days. So, I'm looking for either an NOS or good used unit for my car. 51-3 units are all the same...earlier and later do not interchange.

This would be the small round unit that's mounted to the right rear of the block. A single wire attaches.

Thanks for looking!

These units can often be refurbished- loosen the nut on the terminal so you have some access to the inside. Blast same liberally with WD40, shake, rattle, roll, repeat. Let sit for a day. Then intermittently apply pressure to the end that screws into the block. Monitor the resistance with a VOM. The business component of this part is a rheostat that moves as the pressure increases and changes resistance. I've had good luck with this technique, and the fix seems to last.

Actually this fix works well on all electrical components where corrosion/ goop accumulating twixt contacts is the problem.
