Why do I have blue smoke coming from my piston rings?
Blue oil smoke first appears, when you start your engine, while it is still cold. But, as the engine warms up; the pistons and rings expand, and start to seal the cylinder walls. As a result, reducing how much oil is blowing past the rings. Eventually, the piston rings wear to the point that there is constant blow-by.
Is it necessary to replace ring seal smoke?
Replacing your piston rings is a major job. It involves dismantling your engine and physically removing the pistons to replace the rings. Due to the cost, complexity and time involved, you probably want to avoid this unless it’s absolutely necessary. For many cases, our engineers here have created our Ring Seal Smoke Repair product.
What does smoke mean on a 4 stroke dirt bike?
If it is a 4 stroke, it means that oil is getting past your piston rings. Bluish grey smoke on a 4 stroke is not something that you want to ignore, but if it is light then you can probably at least make it back to the truck. Pistons have rings that allow them to ride up and down the cylinder and create compression.
Can a piston ring be run in dry?
The piston and rings go in absolutely dry but the rest of the engine is lubricated with oil or Lubriplate. I have used this method for over 20 years on car, motorcycle, and aircraft engines with good results. Vernon Fueston ([email protected]) on NOC-L 11th.

Can you run with no oil on the Rings?
However, the proponents of modern thinking now prefer to go with a fine finish (up to 600 grit), and build the engine with no oil on the rings to accelerate seating. It seems hard for me to accept; would anyone care to express opinions on actual results achieved either pro or con?
When do you gas a new piston ring?
As soon as the engine is warm enough to respond to throttle, it’s gas it down the road. As a matter of fact aircraft engine manufacturers say at least 75% power for the first few hours. The combustion pressure holds the rings out against the cylinder wall and for good seating they want lots of pressure, so that means lots of throttle.
What does it mean when your ATV engine is smoking?
Smoke can be an indication of bad cylinders, seals, gaskets or something similar, usually accompanied by gasoline or oil burning in the engine. The cause isn’t too hard to figure out based on the timing and color of the smoke.
What are the signs of worn out piston rings?
So, the first sign of worn out piston rings, is engine blow-by. Consequently, if you are seeing puffs of blue smoke out of the exhaust, it means the engine is burning oil. Also, with worn or damaged piston rings; you may notice that the engine oil gets low, faster than before.
What causes oil to blow past the piston rings?
As a result, reducing how much oil is blowing past the rings. Eventually, the piston rings wear to the point that there is constant blow-by. So, the engine smokes all the time. Another issue with blow-by is combustion gases entering the crankcase. This means fuel and combustion byproducts are in the oil.
How to break in your piston rings, the right way?
The ideal combination is to tune the engine so that it starts on the first or second revolution. For carbureted engines, this means pre-filling the fuel bowls and accurately setting the initial timing. As soon as the engine starts, immediately bring it up to an above-idle speed.
