I'm currently rebuilding my 22RE and would like to know if any of you guys know a good way to clean the baked on carbon build-up off the inside of the intake manifold. I got a the loose greasy stuff off, but a lot is still baked on pretty good.
i recently used a drill bit yo kinda break some of it up from the egr ports then used a bore brush for a 20gauge shotgun to brush it out
