Hey guys, does anyone know if there is a replacement spring for the 3 piece oprv available? I've done some looking around and can only seem to find springs for 911's. I plan on upgrading to the retrofit valve in the near future but for now I want to see if a new spring will fix a few of my problems (oil pump is losing prime overnight and takes around 15 seconds to build pressure again, feels like decades though) anyone here with a black belt in Google fu able to help me out?

Must secure way to avoid disappointment is to buy the new one piece OPRV. Call Lindsey Racing and ask for Mike, tell them T&T Racing , the 944 guy building a stroker engine, sent you
