Ok, first question is, does gm part no. 25525315 (one way check valve) hold up to 25 psi of boost, or were they just barely adequate for 15 psi back in the day.

Question two, as of now, I found out that my egr check valve is tits up. So boost is getting to where it shouldn't be. My first instinct would be just to cap that line off and be done with it, but that's the same line that's tee'ed off to the three way check valve by the fire wall that goes to I think the map on the one side, and to cruise control on the other. If I plug it right where the egr's one way valve goes, what do I do with the other shit until my new check valves get here?
