Intake Manifold Cleaning

[Pontiac1972]

I just installed an EGR delete kit on my truck. Possibly the most painful 3 days of my life. Anyway, once I got the manifold off, I saw that the entire inside of the manifold was caked with soot, about an 1/8 inch in depth, this is including the ports that feed into the engine block. Anyway, I was wondering if anyone knew a way to clean the inside of the manifold without taking it apart again. I was under a time crunch and didn't have the necessary means to clean it thoroughly. The only thing I cleaned thoroughly was the ports themselves and ran some Brakekleen through the rest of it.

I took mine to the machine shop I use and had him stick it in his parts washer.

you're not gonna get that crap out of there without taking it back off

if you have access to a pressure washer that would work.

I had mine put in a nice sauna for a while... (steam bath) As you can see in the pic, it is VERY clean and ready to be put back on.

While you have it off, have you thought about painting it? Might look cool.

I didn't take any pics of the inside, but it was CLEAN... No more crud clinging to side of the air passages.
