I have started the process of cleaning my intercooler. It is going to take a few days because I am working on it after I get home from work. Weekends really aren't an option because I'm working and I would never hear the end of it if I didn't spend the day with the lady on sunday. Anyway, the truck has never had an oil separator on it. So it's as nasty as can be. I have the TB off and cleaned. I also have the plenum off. It is pretty nasty on the inside. I did not take a the pieces on the sides of it off (not sure what they are or called). Can I just spray the inside of that b!tch with carb cleaner with out taking these things off? I will try and post pictures of what I'm talking about. Thanks. O yea, I'm restricted to working during the day because I don't have a garage to work in.
