You will have to buy new plugs.
Piston ring quick fix.
The rings ride within annular grooves in the piston.
Actually it was much worse.
There are two positions in which the rings can get.
The compression rings contain the pressure of the expanding gases within the combustion chamber.
The piston rings themselves only cost between 30 to 150 for the parts.
The piston rings fit into horizontal grooves in the pistons.
The yata had a stuck engine as in would not turn.
Each piston in your car s engine is equipped with two separate compression rings toward the crown of the piston and an oil control ring assembly toward the skirt.
I drained the oil and filled the engine with a combination of diesel fuel pblaster you can buy by the gallon and atf in about a 1 1 1 ratio.
If its a car that car been sitting for a while you can probabaly fix it with out a tear down if its like stuck piston rings.
Stuck piston rings are uncommon but they do occur.
I had a miata with this problem.
This ensures that the engine maintains a consistent level of compression.
It depends on the situation.
