"Chemical Ring Job"
This is from an old communication. Works, messy. You will need to change the oil twice shortly afterwards.
I would suggest doing for a longer period than discussed. then washing pan out with diesel or kerosene.
Not pretty. But works.
This will take a full week if done right, but you can do over a weekend if you want to try a "quickie".
If the car is low on compression and rings not sealing well this might help. It will get the carbon / oily build up off of the pistons as well but you well need to run it hot to burn the residual left off!. There will be gunk in the pan to flush as well.
Start by filling each cylinder with MEK Being sure to get it on the valves. Rocking the pistons to "loosen the carbon`s grip and hourly application of MEK and WD40 will clean the Rings & valves.
Gallon cans of WD 40 can be found at Napa, & most autoparts stores. I bought a gallon last week when I saw it at Harbor Freight! Option is kerosene. Fill liners with MEK. Be sure to get on valves.
If you want to get serious, Get some M.E.K. and pour in and let work for 2or 3 minutes. It will both run through fast and is very caustic which will attack the carbon. If you are at a point where you are going to be around the car, keep running MEK through it, & moving the pistons a bit. Do these steps repeatedly, a couple of times a day for a week will really clean out the gum & carbon. When you are going to leave the car pour in the WD 40 or (kerosene) & turn to coat liners, and continue the cleaning process..
A last serious washdown with MEK, and turning the engine with the plugs in to force through rings should do the deal. Then drain the oil.
Be sure to get MEK on the valves while doing all this, as it will clean them! This is the stuff that is active agent in most carb & FI cleaning compounds. See attached info below.
DON`T SPILL ON PAINT!
MEK (methyl ethyl ketone):
A highly caustic solvent. Always use protective hand and eyewear. Used to dissolve some of the more determined paint problems. Removal of hardened paint on hardware such as hinges and doorknobs by soaking in MEK are common uses for this product. Always test before applying MEK on any object or surface as the powerful solvent qualities of MEK can quickly damage or destroy the item.
Though typically used as a fuel, kerosene has very strong solvent properties. For ‘‘oil glazing’’ in decorative finishing, kerosene is sometimes employed to make the glaze ‘‘hot’’, increasing the workable time with the glaze, as well as ‘‘fusing’’ with a glaze previously applied. No more than a capful per gallon is used and adding kerosene to any paint product is not recommended.
