Stock BOV Problem, leaking Options

[thedrunkfish]

I have recently sold my 6g celica and purchased a st215 gtt caldina. Couldnt find any forums that deal with the caldina so thought i would post here as the 3sgte is very similar to the on in the st205.
The factory blow off valve is leaking, the cover pops off all the time. I can clip the cover back into place and it works ok but then it pops off and just starts leaking again, very frustrating. Do i just need to replace the unit or is it a common problem thats easy to fix.
Cheers.

Thanks for your replies. Yes it is a hard plastic one attached to the air box. I figured the stock one was designed specifically for the engine so i just got another from the wreckers and replaced it, 5 minute job. Boosting very nicely now, I beleive st215 boost 14psi standard 257hp. The other reason i didnt go for hks or turbosmart was the price and i dont particularly want a loud one. Going to hok up the boost gauge tommorrow should be fun.
