Thanks for the responses guys! My BPV seems to be venting correctly now. I guess that the car just had to get used to it lol. Again, xluben, thank you for inadvertently helping me out (again)!

The yellow spring with no shims will in theory hold more boost than you could possibly be making... Xluben has stated this several times in this thread....

Is the goal to get to the amount of spring and shims needed until you get compressor surge then back down a shim?

Old Thread but do any US vendors stock the rebuild kits? My top o-ring tore so i need to get the kit. Buying direct costs more for shipping and it's not a set price and probably no arrival date.

All it would take is for someone to post the exact oring dimensions.

Then you could go online and get some proper orings that are meant for oily environments.

The stuff from autoparts stores might degrade overtime due to blow-by.
