What would make a PRV valve not work properly?
I'm still only building about 1700 psi on this latest 3 cyl 4000.
I took the top cover off again today and hooked a hose so it would pump the oil back into the sump.
I have a good, full flow.
Everything else inside was intact. So I pulled the pump and checked it out. As I mentioned before, from the paint on the bolts it has never been out. Intact gasket confirms that, seals are good. Everything looks good on the pump though you can't do much more than spin the gear.
So Now I'm wondering if maybe it's the prv.
I didn't think to check the paint on the prv before I repainted everything.
I remember having problems on a 3000 once and called the dealer to see how much they were.
He told me his computer said they hadn't sold one it over 10 years. So I didn't buy it and found the problem elsewhere.
I wonder if it could be a problem here.
Also, I guess I could check on Messicks but would a prv from a 3000 work in this system?
I have one of those in a junker.
I'm sure this is something simple.
But if anyone has any ideas I would appreciate hearing them.
PS, that gauge is a new, cheap China Maid job so you never know.
But to be 1K PSI off would be odd.
