It shouldnt have caused any problems. Never heard of one of those lines blowing off.

If he has an aftermarket bov, I could see it happening. Especially if it wasn't properly attached with some type of clamp.

My car is well, it's like 10 lbs of shit in a 5 lb bag...

Are we talking about the hose on top that sends the pressure to open the bov? If we are i have no clamps on mine and i havent had it come off ever. As far as the other hose for recirc. That i know would come off without a clamp.

I thnk he is talking about the little vac line that cuases it to open. I think it should be fine, if anything bad was going to happen, it would have done so when it first happened.

I've blown the hose off before, actually tore it. But that's because when it was cut, it already had a small slice in it. BOV too, not stock BPV.

If it happens again then you should investigate why that is happening.

I would suggest a clamp or a zip tie to secure it.. Unless there is a "one way valve" on an inducted engine any "vacuum" line has Pressure when under boost so any "Vacuum" line can create enough force to push off a bung like the one on the BOV.. The BOV creates resistance thus creating "Back pressure" thus pushing it off the bung.. If not for the "Barb" at the end of the Bung on the HKS BOV mine would pop off even with the clamp that's on it. As it is now it slides till the clamp hits the barb.

Well ya it will have positive pressure and negative but it still shouldnt pop off. Maybe the tube the hose connects to doest have the right shape to hold it on.
