Been chasing low boost problem. Yesterday decided to clean the BCV. Sprayed WD40 into all 3 nipples. Then when I shot compressed air into two nipples with no problem. Air into the final fitting ("R" I believe), the valve body popped apart in my hands. And I mean it went "POP"!...
Is that expected or does that indicate something was plugged up?
Also... when it blew apart, a shiny metal slug of some sort fell out. I can't find that piece. What would that piece be?
I put it back together and drove the car very gently to watch for overboost. On gentle throttle it's fine, but I did hit fuel cutoff when I got on it a bit. So, as expected, the BPC isn't doing its job now. Any help much appreciated!
