Where to get new crush washer for oil pressure switch

[ErrorMargin]

I've got the engine out of my 84 Targa and am going through the triangle of death.

My oil pressure switch is not leaking, and I've put JB Weld on it to hopefully prevent it from leaking in the future.

I'd like to put a new crush washer on it before I put it back on the engine, but I cannot find just the washer.

Does anyone have a part number or just specs for the washer?

Should I buy a new switch just to get to washer or just put a new switch on there?

This is the switch: https://www.pelicanparts.com/More_Info/91160623000.htm?pn=911-606-230-00-OEM&bc=c&SVSVSI=0581

I think this is the crush washer p/n - 90012300830

standard 14mm x 20 mm washer.

OP, which washer are you referring to? Obviously there is the tiny one which is shown on the product photograph on the link you shared. Doesn't look like the PET shows that one. If, however, you're looking for #51 on the diagram below, that part number is 900 123 007 30.

It’s about $!0 for new switch and it comes with washer attached.
The PET Show the turbo stack which is more complex.

Agreed. I got the $33 one, but obviously it's brand new and should last quite a while, plus the new washer included.

Ace Hardware and others sell copper washers.

An old motorcycle trick I learned was to anneal copper washers , simply heat till red hot and dip in cold water. This will soften the copper so it will reseal.
