Take it apart and lube moving parts. Old used BOV’s can sieze. And running for 1 hour without a BOV won’t wreck your turbo. ---

Did you delete the ricirc valve completely? It’s not going to idle well unless you do that. There are three vac sources. 2 on top and 1 on the bottom. You need to have it’s own dedicated source for the BOV. Like I said earlier, delete the evap canister and use that line. Make sure the lower vac source is plugged up. Run the other top one for the FPR and whatever else you may have. ---

How much boost are you running…my guess is the spring in the bov is too stiff? i had it happen to me…i was running 7psi on a min 10psi spring and it wouldnt fully go off all the time ---

yea i think i;m running stock boost rite now…yea i;m guessing i have to run a lil bit more to get it to open…but what worries me is that when it idles now…the engine shakes and vibrates pretty rough …but the rpm is idles normal any ideas ---

for me the vacuum source on the bottom of the TB won’t actuate my BOV. I had to use one of the top 2 vacuum nipples. and yeah… if the shaking in your idle happens right after you rev, its a vacuum leak either caused by the bov itself or part of the piping/couplers/gaskets that you recently installed when putting in the bov. ---

Cutting the spring will not help, youll just get bad boost leaks. Go to matrix (I think they sell Blitz) and just shell out for a new spring. ---
