Piston rings are always installed with the numbers up toward the top of the piston
As the piston moves up and down in the cylinder it also moves the piston rings up and down in the grooves. With the rings moving up and down it gradually increases the side clearence. Material is taken off from both the piston groove and the ring.
Could be a blown head gasket or the piston rings Could be a blown head gasket or the piston rings
The "cylinder jug" is the cylinder. This is the area that the piston and piston rings moves up and down in when the engine is turning.
bad piston rings or a bad cylinder all together look up a rebuilder bad piston rings or a bad cylinder all together look up a rebuilder Worn piston rings and or bad valve seals. Could be from high mileage or poor maintenance either way there is no cheap fix.
do not put ring openings up and down in a row
Place rings into their respective positions on the piston. Place ring compressor over rings and tighten up until you can only just move the piston inside the compressor. Place the top of the piston into the bottom of the cylinder, push the piston and rings up out out of the compressor and into the cylinder keeping the compressor hard against the base of the cylinder. If you do not hold the compressor hard against cylinder the rings will slip out and you start again, you are not allowed to throw the compressor at your garage door until the third time. You should try it without a compressor, or have you?.
In a internal combustion engine, a cylinder ridge is an unworn area around the top of the cylinder wall. In that engine, the piston moves up and down in the cylinder, and the rings seal the piston in that cylinder. But the rings are spaced "down a bit" from the top of the piston. And when the piston reaches top dead center in the cylinder, the rings haven't gone all they way to the top of the cylinder. They end up wearing the cylinder out "underneath" that top area. In other words, it's the top part of the cylinder that is not in contact with the piston rings. It's the "unworn" part, if you will.
No. Saturn's rings are made up off bits of rock, ice and other objects that are pulled into orbit and have stuck and partially stuck together.
A stuck lifter, a stuck rocker, a stuck valve, a messed-up cam drive timing and a valve impacting the piston head....
Blow by is caused by worn, broken or sticking rings. It's a condition where exhaust gas leaks past the piston, into the crankcase. If severe enough, sufficient pressure can build in the crankcase to push oil out the crankshaft seals, damaging the crankcase seals, or it can cause leaking at gaskets or even push oil vapor through the breather tube. It's possible to SOMETIMES free up sticking rings by using an engine crankcase flush solution, but that only works if the piston rings are stuck in the ring groves from a history of poor maintenance. Blow by is the single most significant reason for wanting to keep your oil changed.
blown piston rings or valves in the cylinder head not seating properly
