hey whats up guys, im in the middle of a build for more power. I plan on using the intercooler from ym old set up until i came across something today... i stuck my hand into the end tank on the side where the charge pipe goes into the IM. and i stuck my finger in and got some black residue stuff... it didn't feel like oil.... but it was almost crusty.... the turbo i had before i think was leaking oil or something... but im a little worried there might be some stuff in the intercooler... the side where the turbo pipe bolts to the other end tank is clean very minimal black stuff. its almost looks like the stuff that comes outta my exhaust but maybe a little wetter. So now the question is.. what is the best way to clean out my IC?? also my car was running a bit rich... that maybe the reason for the excesss black stuff?


any thoughts?


thanks in advance...

 

its probably oil baked in it

brake cleaner , water hose and air hose

 

is this normal for all other intercoolers though? i thought end tanks were supposed to be spotless.

Nothing that occurs in the combustion chamber should leave its mark in the intercooler...meaning the only way for "rich" gases to get into the intercooler would be to go backwards through the intake manifold....you would know if that happens.

If you have a PCV or any other type of ventilation hose from the then into the intake piping, its probably just normal oil vapor getting sucked. If its dry, it won't hurt anything, and if its wet it still wouldn't really hurt anything.

Brake cleaner, or that "foaming" engine bay cleaner stuff work great. Just spray in both ends and turn the intercooler around a couple times so the liqud gets everywhere. Let it sit for about 10 minutes and then do the same thing with the garden hose to clean it out. Or if your real concerned about the contents of your cities water, go to Wal-Mart and buy 5 of the $0.70 gallon deionized water jugs.

 

i think im gonna hit up wal mart tommorow.


thanks
