Bad piston rings. Get new engine.
bad piston rings Excessive engine wear - Rings, Valve guides, Valve seals
the engine will not missfire with bad rings, the srark plug will still ignite the fuel in the combustion chamber. you just may not have enough force down on the power stroke
They usually last forever if you replace the engine and replace parts!It will be bad on Gas Milage though......
it is bad for the catalytic converter and O2 sensor. It is also bad for the environment. Your engine also has less power due to the worn rings and loss of compression.
You probably have bad rings in at least one of your pistons.
The rings are like a gasket between the engine and the pistons. explosions happen in the engine which push the pistons to turn the engine and keep it going. If the rings are bad the explosion escapes and doesnt push pistons like its supposed to and engine wont run.
Engine "Blow-by" caused by excessive engine wear usually bad piston rings
Bad bearings or bad piston rings
