Turbo question : Check valves

[Phoenix]

Ive been all over to find a good check valve to avoid boosting in the booster and the BBBs canister.

Now Ive read that a Supra turbo PCV does the job flawlessly. Input?

Brake booster should already have a check valve in it and I know the secondary canister does. I run a check valve on nothing without issue. I may put one on cruise canister when I fix it.... I'm wondering if boost broke the ****** off on mine as I didn't bump it.

Biggest thing is to not plumb PCV hoses into a boosted manifold.

I can't give advice about boost with a SHO but I run 15psi boost on my 2.3 for my daily driver. I use a Ford PCV valve [not the parts house one's they are junk. They will let boost bleed thru]for my pcv system. I also have a brass one in line. I have a small check valve in my vac line to my trans and a vent on trans side to vent it. [Have read not necessary on c-4]. So I recommend getting a Ford part only PCV valve. I have non on the brake boost. 4+ years like this no brake booster failure or braking problem. Maurice

I was interested in this as well. The secondaries were unplugged on my most recent acquisition - I didn't know if that was on purpose to keep them open, or if they just forgot it (based on the rest of the car I assumed they forgot).
