PSA HKS 51MM RACING BOV

PSA:

For anyone running the HKS 51mm Racing BOV, check the bolt tightness on them or remove them and apply blue Loctite. Brand new unit and I'm at about ~3,000KMS (~1,900 miles) on the unit and 5 bolts are completely missing from the nose cone and the 6th one is barely in there. The back side also had some that weren't as tight as they should've been. Appears they used some sort of thread locker but it either isn't strong enough or they didn't go right enough. Also replace the vacuum fitting with a brass one. It's M6x1.0 thread pitch and I opted to throw an aluminum crush washer in there as well. The factory one is some sort of aluminum or soft metal because it snapped when I tried to remove the vacuum hose on it earlier in the year. Also if you're buying this hoping for any noise you'll be greatly disappointed, I actually thought it was defective but tested it and it moves air, just no noise (I have a turbo w/ the T51R mod so I still get lots of turbo noise). Still a decent product does its job but some small issues with it I've had personally.
