    Which goes in first, the spring or the ball?

    Yes I'm an idiot. lol

    FYI I run pbc parallel with n75

    Last week I decided to jb weld the bleed hole. after I did that it wasnt boosting as high so I was trying to adjust the boost and no matter what I do it boosts the same.

    So tonight I took it apart and got the ball and the spring to come out and when I went to put it back together I wasnt sure which should go in first.

    Lets put it this way, I know the ball was in there first and the spring was on top and the screw pressed against the spring, but I got to wondering if I put it in there wrong in the past.

    I'm doing some searching, but if anyone knows the correct way it goes together. please chime in.

    Thx

    Re: I took my mbc apart and now I cant remember...

    Well I did some research and thought about it and answered my own question with just using common sense.

    According to the below diagram the bottom hose of mbc is boost pressure so pressure would be pushing the steel ball up, so if I put the spring in first then the ball against the screw, it wouldnt make any sense because the ball wouldnt move at all.

    So it was in there correctly before. having the steel ball at bottom then the spring between the steel ball and the bolt.

    Well at least thats what made sense to me. If I am wrong feel free to correct me.
