BrandonspecB Posted October 27, 2013 Share Posted October 27, 2013 Sorry, I should've been more specific. All piston based diaphragm-less BOVs leak to some degree. Don't really understand why your stock unmodded BOV is leaking that much though. That sounds like a pretty insane amount... I think it's just old. It has around 90,000 miles on it.

JMLegacy Posted March 12, 2017 Share Posted March 12, 2017 OK. Trying to understand how to mod the stock plastic BPV. All I do is block the small hole? As in, I fail to see the reason to drill the atmospheric hole. Link to comment Share on other sites More sharing options...
hadvw Posted March 12, 2017 Share Posted March 12, 2017 OK. Trying to understand how to mod the stock plastic BPV. All I do is block the small hole? You also need to drill a new hole to replace the one you're blocking. Read the thread linked in post #1. Link to comment Share on other sites More sharing options...
JMLegacy Posted March 12, 2017 Share Posted March 12, 2017 Nevermind, i just did both. They weren't lying about the compressor surge either. I feel I wanna go back. haha. Gonna source a stock BPV. Mine is JDM though, not sure if it's different as I couldn't move the plunger with any other finger but my thumb. Link to comment Share on other sites More sharing options...
