Better than and Sea Foam and possibly MCCC

Piston top carbon cleaning.
Well I tried the Sea foam and it didn't do Squat. Just made alot of smoke. My piston was still full of carbon. I poured it into the cylinder and waited 24 hrs and even poured 2 cans in the tank. I tried many things on the market but nothing worked to my liking. Took off some but not all. I even ran the car a little lean in hopes to create enough heat to "Burn" off carbon. Still had carbon. Well untill I tried something I had for a while. Let me tell you It worked!!!
Pistons are nice and clean and I didn't even take off the head to get them like that. And I really mean CLEAN. Not one spec of Carbon. Best of all it worked in minutes, right before my very eyes. Insta-results!!!!! And from what I have read about MCCC, this works better than even that!!!(From my personal experience)

Well its called Chem-Dip carburetor and Parts cleaner. Yep thats right by Berryman. (Sold at Kragen) Its sold in a Gallon can. Its nasty stuff (Like acid) and its used to clean parts when rebuilding or whatever. I used this stuff on my throttle body and my Go-Cart's 8HP engine piston and valves and it gets the job done. (Only I used it as it was meant to be used) So I decided what the hell, My engine is old, lets try it. (135,000miles)
Heres what I did.
You will need a funnel with a hose, The Chem-dip, Fresh spark plugs, a bunch of rags, a flash light and A can of carburetor spray.
I ran the car on the freeway to get it nice and hot. Than went home and shut it off and quickly removed the spark plugs. Looked down with the flash light to see the nasty tops. Now you can choose how you want to do this. I did it both ways. You can either do one Piston at a time (Permits easy starting while cleaning) or you can do all at the same time (Harder to start car but faster in the end).
After taking out the plugs pour enough of this stuff to just cover the piston tops with the funnel. The funnel has to be able to reach into the hole. Thats why you need the one with a hose attached which you can find at Walmart. With this funnel it has a close off valve so you can measure the fluids. Add a bit more if they are really carboned up. Wait anywhere from 15-30 minutes. Don't have to wait longer cause it works best with hot pistons and the little bit you put in there will get carboned real quick. Put back the plug or plugs. Just screw them in two to three turns so that you won't cause any build up on compression. (Do NOT seat the plugs!) Air will escape but car will still start. Put back the spark plug wires. They will stick up but thats ok. Now if you did all at the same time, get in the car and crank it over a few times. If it has not started, Go back and remove plugs and dry them off with the rags. You will notice that the stuff is now really black. Reinstall plugs in the same way screwing them in like 3 turns. Crank it and when it fires up hold the RPMs at around 3K. If doing one at a time it will start right away. Hold rpms steady at 3K. (With one at a time, only the plug that you are cleaning has to be unseated. The rest of them can be fully seated) It will emit blue smoke that really stinks and sputter at first. Than Keep it there for like 1-2 minutes. Let go off the gas and it should still idle by itself like normal. Shut it down. Remove plugs and look down in the holes. The pistons will be either 50% clean or more. Repeat entire process. (Took me 2 times with the exception of piston 4 which took 3 times) After its all clean take your Carburetor spray and clean the spark plug holes from the overspill, cause when this stuff drys it becomes really sticky. Makes screwing in the plugs harder. If you spilled some of this stuff on anything just wipe it up with a wet rag. Re install plugs and take it out for a nice drive. Don't have to race it. The drive will clean it really nice. Come back and check again. When satified Put in fresh plugs and change the oil.
My piston tops are really clean now. Looks silver rather than black! I can see the Big T and even see 63D on each of them. Never even knew they had other writing on them. Anyway this is the fastest method next to removing the head and cleaning them by hand. Chem-Dip is safe to use on all metals, even aluminum and the normal way to clean parts is dip parts in this stuff (As it has a tray in the can) and after taking parts out washing them with Hot water. Well I did all of this with Hot pistons and used fuel to wash piston tops (By starting car) Car seems to have a bit more pep now as well. I finally got results.
