This may have been asked before but does anyone have a part number for the oil check valve used on the STS remote mount turbo? Thanks....Ken.

 

I have no idea what STS uses but this is what I've used for over a year and 10k miles. Whatever valve you use put it close to the turbo.

Thanks for the link.

 

I used Summit check valves, i can't recall the part numbers off hand but you can search their site and find them pretty quickly. I have a 4 an supply side valve and a 10 an return side valve after the return pump.

 

Yes, the Summit one is ideal because it has a low crack pressure, but they have been on backorder. I've gotten the one recommended by SpartanSV which has a 7psi crack pressure which seems high but worked for him.

 

7 psi should be ok, as soon as you start the car the oil pressure is above 7.

 

Got it.
