I want to remove all carbon buildup from my ported IM before bolting it back on - yeah, I am blocking off EGR so it doesnt happen again.

Is there a DIY method to do this or just get it hot tanked somewhere? Thanks!

 

I'm assuming this is the one off your car?

If so, I used brake cleaner and a small toilet bowl brush... brake cleaner is good because it dries instantly. Toilet bowl brush well it's rough enough to no damage the metal...

Just watch out for the turds on the brush

 

Its the one "we" got back from mil.spec, Erich! It has some carbon build-up. Someone said to try gasket remover as well...

Did you put the brush thru the TB hole and scrub away?

 

I should have noted, that was a BRAND new brush...

Did Aby do the porting? I was wondering about this same thing, with my next purchase of the 65mm TB and Ported IM. Would be nice if this was done with them in house.

 

Yes, Aby ported it. I don't see shavings and such, but I can see a lot of carbon residue which I want to get rid off, thats all....

 

I just used throttle body cleaner when I did it on my miata.

 

Gasket remover probably will give me cancer. The carbon literally bubbles up and melts away. Its great if your lazy. You really don't even have to scrub it. Just spray, walk away for 5 minutes. Spray some more... walk away... spray again... walk away... then rinse it in hot water. At this point 80% will be gone. A couple more shots on the tough spots and it will be perfectly clean. Use REALLY hot water. As you flush something like the IM. It will start to get nice and warm. Which is nice because then you can shake it. Set it down - come back 3 minutes later and its 90% dry. And you can start spraying again.

Beware of aircraft stripper! It will seriously F! you up. And NOT in a good way.

Also... don't try to "hurry it along" by blasting a part covered in gasket remover with brake cleaner. Atleast... not if you enjoy being able to breathe.

 

well it would be best if you had a parts cleaner bin and had it soaking in parts cleaner solvent, or I have cleaned a few by using brake cleaner, it was tough to still get in all the areas of the intake manifold since it dried very quickly.

 

i agree with hot tanked or try simple green i think its more for buld up in the valves tho you should be able to find this at any autoparts store

 

But doesn't that mean it works better?


Aircraft stripper is how I did two intake manifolds, and two throttle bodies.

It works extremely well, but, get some on you and it hurts like hell.

 

Good aluminum cleaning solvents are noncorrosive nonpolar thinners, strippers (as mentioned), and some inert chloro/flouro hydrocarbons. Just cleaned 60,000 miles of intercooler crud with oderless mineral spirits. Made the inside shiny and the rinse collected looked like printer ink. I can actually hear the air going through the intercooler again.

 

Get Some Gm Top Engine Cleaner..

 

1 can of parts/tb/carb/brake cleaner, thats all ya need.
