Does not work on miata

The spring is too strong. In the softest position, the valve does not close properly. In a more rigid position, the valve will close but not open under vacuum. lets me chase my tail There are 2 o-rings, one on the bottom of the piston is too tight around the piston, it will catch on the piston. Difficult to open and then close. Dissatisfied customer.

Pros
  • Turbocharger and supercharger parts

I was planning on hooking it up to a trap as the exhaust was throwing oil into my engine bay since I was using a vented to atmosphere configuration. This is normal as the 335i has a lot of blow-by from the factory. I already have a siphon installed, but the blow-by gas from the pressure pipe was enough to thinly coat my outer…
