Many people think that the piston ring groove’s only work is to support the piston rings. Not true; the piston ring grooves have several other uses.
They help in sealing combustion pressure, blow-by, and oil control.
The piston ring groove must give the piston ring enough freedom to move. So that the ring can bear high cylinder pressure, the ring groove must provide a hard, flat sealing surface.
The piston ring grooves perform all these functions, and therefore, are prone to becoming dirty. If you are unsure how to clean them, follow our guide on cleaning piston ring grooves.
How To Clean Your Piston Ring Grooves
The reason why your piston ring grooves need cleaning is to make sure there is back clearance. There should be enough space between the bottom of the piston groove and the back of the piston ring.
If the clearance is insufficient when the rings and the piston are installed, they can cause severe engine damage.
Therefore the need to know how to clean the piston ring grooves. You can use the procedure below:
- The first thing you need to do is get a piston ring groove cleaner. Then remove the piston rings. You will need to do this carefully not to damage the piston.
- Use a seafoam spray and ensure it gets in the piston ring groove.
- Set the piston ring groove cleaner and slide it up with the cutting edge.
- You can then spin the piston ring groove cleaner to clean the groove’s carbon. Apart from the carbon, it will also clean out any rust or sediment accumulated in the piston ring groove.
- Do this until you start seeing shining metal; you can now stop. If you continue, you will be cutting through the piston, thus damaging it.
Practical Ways Of Cleaning Your Piston Ring Grooves
There are other ways to clean your piston ring groove without using the ring groove cleaner. So if you are not in a position to buy the piston groove cleaner, you can use the following methods.
Wooden Or Plastic Scraper
Scrape off the carbon build-up in the piston ring grooves using a wooden or plastic scraper.
If the deposits are stubborn, you can use a putty knife. To clean the remaining residues, soak in the solvent.
You can use solvents like the brake, carb cleaner, or purple flower.
After scrapping off the carbon using old piston rings, go ahead and soak your piston ring groove in any of the solvents. Solvents can be the easiest way to clean your piston ring groove.
A Mixture Of Baking Powder And Carbon
Some solvents will not work well and may damage your piston if made from aluminum. The best to use is a mixture of baking powder and carbon.
HHO Carbon Cleaner
You will not need to dismantle any parts for this cleaner. It is safer and more effective in removing carbon from engine components.
The cleaning agent is fed into the combustion chamber, where the combination of air and fuel forms water vapor.
Combining the two will create conditions for the two to be gently burned off the piston ring grooves. The HHO carbon cleaner is the easiest way to clean your piston ring grooves.
WD-40 Removes Carbon Residue
Here is another cleaning agent you can use for cleaning your piston ring grooves. It can easily remove any carbon residue formulated inside your piston ring grooves.
WD-40 is used for so many functions in the house, so there is a possibility you already have it. It can do a fantastic job of cleaning piston ring grooves.
Soft Pine Soap And Water
Put your piston in a pan with some soft pine soap and water and let it boil for half an hour. Remove and let it cool, and all the carbon residue will be gone.
But you can still use a sharp instrument to scrape off the inside of your piston ring grooves. To prevent rusting, you can apply some 2T oil.
Using soft pine soap and water is the cheapest way to clean your piston ring grooves.
Using Berryman Chem-Dip
If you don’t want to do a lot of scrapping, this is one chemical that will help you out. Put your piston ring grooves to soak overnight.
Please remove them and put them in some clean water. Your piston ring grooves will be free from carbon.
Don’t use just any oven cleaner. Most oven cleaners contain lye (Sodium Hydroxide) that will corrode aluminum.
Spray the oven cleaner on the piston ring grooves and leave it for one hour. Put it in a bowl of clean water.
There you have another easy and cheap way to clean your piston ring grooves.
Acetone And Automatic Transmission Fluid
Here is another creative way to clean your piston ring grooves. Put 50% acetone and 50% automatic transmission fluid in a glass jar.
Mix them well. Pour the mixture onto your piston ring grooves and watch how the carbon will be off after a few minutes.
Seaform To Remove Carbon
Take a can of seafoam and spray around your piston ring grooves. You can also spray it into a fitting container and dip your piston ring grooves.
After two hours, you can use a soft brush to clean off the remaining carbon.
CRC GDI IVD Cleaner
It is another cleaner you can use to clear carbon build-up in your piston ring grooves. Pour it into a fitting plastic container.
Put your piston ring groove and after two hours, remove it. Use a soft brush or a cloth to remove the carbon build-up.
While cleaning your piston ring grooves, one thing you must take note of is that this is the metal you are cleaning. Some of the products you will use to clean are corrosive.
You might also need to use sharp objects like old piston rings. Hence, the need to wear protective clothing like grooves or googles.
Where you have used water to clean off the piston ring grooves, make sure they dry completely to avoid rusting. You can blast with some air and lubricate also.
Reason For Using A Piston Ring Groove Cleaner
Most people will use carbon or brake cleaner to clean their piston ring grooves. Others use the old piston rings to clean the piston ring grooves.
While those three methods are as effective, they may damage coated piston ring grooves.
Hence the preference for the piston ring groove cleaner. If you find it a bit technical, you can still remove the tool’s die and use your hands.
Piston ring groove cleaner is the only method to clean your piston ring groove thoroughly.
