Clean Your Boost Controller!

[ABV]

In the quest to find out why my car wouldn't boost past 7psi, I checked all the intake and IC piping, all the vacuum lines etc, and finally took off the BC, and the MoFo was dirty as hell. I guess there was enough dirt and gunk in there that the ball wouldn't seat against the fitting, so basically there was a free path to the wastegate actuator, thus no boost.

Moral of the story. Check and clean out your boost controller regularly. ;)

How long have you had it on the car.

i'm guessing your just using water to clean this out?

I wouldnt use water... as it corrodes or rusts. Maybe use WD-40 or some other type of degreaser.

Aluminum and stainless steel don't rust.

Uhh.. smart guy you are...

Maybe there are steel parts on it like the washers or whatever. Mines made of brass and steel so whatever.

Aluminum corrodes thats why I put corrodes... Steel rusts there for I put rusts.

Geez :razz2:

Corrosion of metals is from oxidization, which is just as easily caused by the oxygen in the air as it is by the oxygen in water. Most, if not all manual boost controllers are made of aluminum bodies, aluminum or brass fittings, and stainless steel balls and springs. If any of the parts are mild steel they'll rust the same as if they're touched by water or not.

Do you think Im stupid or something?? Everytime I suggest something that is beneficial you always try and top me... its like a game or something.

I know what rust and oxidation and corrosion do I have dealt with many many examples and I know that if water comes in contact with steel or aluminum a chemical reaction occurs and the water starts to eat through the metal after a Log ass time. But surface corrosion can be just as bad. I know my Joe P MBC has a turn dial which is painted black and made of steel. Its already rusting....

Air does not cause near the amount of corrosion as does water. Just like in the thread about using straight water instead of antifreeze. Water is water a chemical reaction still occurs.

Salt on the other hand really speeds things up.


ANYWAY back to the topic of cleaning MBC's. If you use water make sure you blow it all out and dry it really well. ;)

Wouldn't Carb-cleaner be the best? I mean, it is designed to do exactly what you guys are describing. Just a thought.
