removing carbon build up

[kylaris]

I took the head off to install the headgasket and noticed lot of carbon build up on piston and head.
I used carb cleaner, but didn't work so well.
What do you use to remove it? Anyone know any good solution?

thanks,

You can try degreaser, seafoam or ask somebody in a auto parts store.

[kylaris]

I've tried sea foam too. didn't do much good.
any other suggestions?

I just used brakleen and a rag, and scrubbed.

carb cleaner or brake cleaner with a rag should be ennough to take off carbon buildup.

take purple power and spray it on the top of the piston. Let it soak for about a minute. Then wipe it off. Purple power is very strong so be careful with it.

And with the head your best bet is to take apart the head and get it decked and hot tanked/degreased. It will come out like new. It only cost me 45 dollars to deck the head and 15 dollars to degrease.

I would be careful hot tanking aluminum parts.

I would be carefull with nocking carbon buildup free in a motor. I had carbon build up clog the oil pickup in a ka, leading to oil starvation/rod knock.

That was probabyl true 10-15 years ago, but today 99% of machine shops have a formula/solution that is save for all engine parts, as nowadays aluminum heads/blocks are becomming the norm.

Both will work just fine. I also suggest using a scotch brite and or brillo pad to help :D

dude, dont scrub the shit out of a alluminum part... its BAD...... and never use a steel wire brush.. use brass.... if i were you, get a cam of gasket remover and a old toothbrush.... and just wash it off after... it works real good .. i cleaned inside intake and exhaust ports this way on a KA head and numerous miata engines..

Didn't know that. :D I've just always been told the usual horror stories of people leaving an aluminum head in a hot tank over night.

[2fourD]

i've heard of some people soaking it in kerosene.

[georgesal]

carbon is very a very hard substance if you get seome of that stuff between your piston and cylinder wall which i bet you alread have it can score them and cause you to burn excessive amounts of oil. leafve it in there it adds compression hha j/k about hte last part

Heheh, I was the same way as you when I went to get my aftermarket v8 heads cleaned up, but the shops all said that hte current solution is safe on them all :D

[daryl337]

Yeah, the solvents we use at this point are safe for aluminum.

As far as removing carbon build up, dont be shy to get some sort of solvent and have at it as long as you dont scar anything up, and you make sure you clean up afterwards. You get that stuff down your cylinders and your rings are going to pick them up, gall your walls, and eventually that stuff is going to get into your oil. Purple power does work pretty good.

Go to your local Dodge/Chrysler dealership and ask for some MCCC (Mopar Combustion Chamber Cleaner) Part #04318001. It comes in a spray can. Spray some on your pistons and head and let it sit over night. Coat it good so there is a little puddle of it sitting on top of your pistons and head. Wipe it out the next day and your pistons and head will almost look like new. MCCC will eat thru the carbon build up like no other. Its awesome stuff.
