I've had a Greddy type-r bov on my car for about 2-3 years now. I have never noticed this problem before so I'm assuming it isn't supposed to do this and is indeed a problem. I started having a problem with my car not wanting to boost past 25-26 psi, so I pulled out the boost leak tester. Found a few small leaks and fixed them but the intake system would still not hold more than 20-21 psi during the test. I know very few dsm guys use the type r but it is designed the same way as the type s. It has 2 nipples, one on the "head" of the bov and one on the body. The nipple on the head gets attached to a vacuum/boost line after the throttle and the nipple on the body either gets left vented or gets connected to a boost source after the compressor and before the throttle. I've left the nipple on the body vented since I had the bov. When I do a boost leak test as soon as I build up about 10 psi in the system is starts to leak out of this nipple and obviously out of the entire system. If I cap the nipple or hook the nipple up how it is supposed hooked up to the nipple on my compressor cover, the bov starts to leak out of the "mouth" at anything past 10psi. With the nipple vented I can't boost past 25-26 psi with my MBC all the way in, and with it hooked up I can't boost past 16-17psi. I know I can reach 32 psi+ with my wastegate spring and boost controller b/c I have been at this level before with the same setup. My question is do you guys think the diaphragm is damaged or is something else with the bov damaged? I'm really not sure what the problem could be. Any input would help. Thanks
