Quincy Compressor LVD unloader leak

[250]

I know there are a few Quincy compressor experts out there and I'm hoping the answer can be found.

My pilot has a leak that comes out of the small hole in the end of the pilot valve. I've corresponded with my favorite compressor supply shop as well as the Quincy tech help for Norcal and all I've really been able to determine is the replacement assembly part number.

Since I didn't have much to lose, I pulled the unit apart to see if there was something obvious, like some gunk or what not on the check ball. The picture is what I found. I'm pretty sure that plunger shouldn't be bent, but how would something like that get bent? From what I can tell it's a thumb screw and spring that applies pressure, not exactly a lot of lateral force.

Any suggestions are appreciated.

Probably something smacked it end-on, or it was pushed against something. Maybe someone torqued it down madly trying to get it to seal? Definitely should be straight.

I tried straightening it out, but there was no improvement. Still leaks out the top at the end of the cycle. In fact the continuous run function now doesn't work, it acts like something binds and it can't quite unload. Probably time to look for replacement unless there is something else I should be looking at?

Looks like plier marks on the thumb screw
