just so you know, 2nd gen bov's are plastic, so if you got a crushed one you bought a pile of ----
if you even bought a second gen, then you bought a piece of ----

the best BOV out there period is the 2nd gen Mr2 BOV, it responds the fastest. dual diaphram, responds to changes in manifold pressure, not vacumn itself, i can actually make the bov go off while boosting by playing with the throttle. its fuckign sweet. its pretty loud, you could make it louder by blocking off some of the passage to get a louder sound. The HKS SSQ is a copy of this BOV.

O and did I mention this baby doesn't open at idle?

best bov ever in my opinion.

YES, the SPRING IS TOO TIGHT.

I always cut a few coils on them prior to install.

However, on MAF equipped cars, that tight spring is the solution to idle problems.

Dude said he cut a few coils on the spring and it's still too tight?

quite possible. Cutting the spring is an adjustment. You can cut too much, or too little.
If it'S still too stiff, he has to cut more. after that, The whole cap of the BOV can be screwed in or out for fine tuning anyways. If you cut too much, then you can always add a few washers to make it stiff again.
