Just as the title says my intake manifold needs a good cleaning. I tried using carb cleaner, even brake clean, but the carbon build up is pretty significant. I was wondering what you guys would suggest to clean it? I was told to leave it in a bucket of gasoline for a day or two, but I'm not too sure about that. Any suggestions?

A bucket of gasoline? That's just stupid and a waste. What do you do with the gas afterwards? Dump it in the car? lol

If you know of any shop that would just do you a favour, tell them to send it through the parts washer. Varsol and a stiff bristled brush will work well too, just won't be able to get all the way into the runners. If it's hard carbon, use a screwdriver to chip it off.

How about throttlebody cleaner?

you could probably just hit it with some scotchbright with a solvent and not too much pressure. Not like its clearcoated.........

I've had good results with WD-40 and a shop towel.

im assuming we are talking about the exterior of the intake?

i would think soak it in that foaming engine bright, and some scotch bright, or if you really wanted a wire wheel and a Powder coat shop

Um, the interior is where the carbon build up is. I need to clean the inside of it.

T.B cleaner, or try seafoaming it (but that would require it to be bolted down to the motor)
