I have the throttle body off the jeep for the night, (getting a good soak and waiting on a new gasket). I was looking down the intake and its pretty dark and crusty in there! Just wondering what everyones opinion on the best way to clean it would be? Thanks

 

Pull it off and go to the nearest DIY car wash and spray it down with the pressure washer, they usually have an "engine cleaner" option. You do not want to clean it while it's on the vehicle if it's that bad otherwise you're prone to sucking that crap into the engine.

 

I just had this done several weeks ago since I was doing a head swap. I took it to my local parts store and they have a boil tank that cleaned it up like brand new.

 

thats what i thought everyone was going to say! i wasn't to keen on the idea of taking it off, not that i can't i just didn't want to tear into it that bad!
