Not on my 335 but my A4 turbo. It was actually the house going into the intake manifold. You want to talk about a pop. I spike to around 23 psi in that car and didn't have it tightened down enough. Thought the engine had just dropped out of the car
Scared shitless until I saw it flapping in the breeze. Whew!

Clean the surfaces with alcohol and use t-bolt clamps.

He doesn't know the cause. We are speculating based on his "claim" of it "popping" while on throttle. Although it may have seemed to him that it "popped" while on throttle, its quite possible that the thing was already starting to come off just before he got on the throttle when he lifted the throttle to change gears, causing excess pressure which didn't get released by the BOV.

Again, its all speculation.

Well we may never know then since he didn't have a data acquisition system on at the time even though it's a pretty common occurrence on other FI cars.

Does the hose look like its "ballooning" from excessive pressure, or does it look like that just because the hose is "off?"

OMGz teh BOVz cause it to exPloDe y0... you must need forged DV's instead.

Listen, its not the end of the world, you stepped on the gas and your coupler popped off, its no big deal. When I first turbo'd my s2000 I blew off silicone couplers a few times, which almost caused me to have a heart attack the first time when the car just fell on its face and there was no boost , but some Tbolt clamps really do work well at holding on the silicone couplers. Did your BOV come with those crap clamps from AA? I *think* mine are different, but I don't remember exactly what clamps it came with. In any case, tighten it down (preferably with a better clamp), and problem solved.

They are usually pretty flexible... I think its just the way that its sitting half off the pipe. Also, when a coupler blows off a charge pipe it makes a distinctive "pop" for lack of a better word. I don't think there was any excess pressure that wasn't released causing the clamp to come off.

Better clamp, problem solved.

Thanks for all the input guys.

I finally got the 'crappy' hose clamps off and replaced them with T-bolt clamps. Also wiped the excess oil that got on the hose and pipe. So far so good, but then again, it's probably too soon to say.

I guess I'll just have to wait and seee........

P.S. Yes, those were the clamps that came with the AA BOV.......Now I know why they're SIHT
