Which Piston Ring Goes On top wiseco?

The top ring is subject to the most intense heat and pressure, and the second ring is its “backup” and does double duty metering oil that makes it past the lower, oil ring. Because of this, their designs are sometimes different, so you need to make sure the right ring goes in the right piston groove.

Which Piston Ring Goes On top black or silver?

What is the purpose of the top piston ring?

The primary role of the top compression ring is to seal off the majority of the combustion gases to ensure you get the maximum power output from your engine. Any failure or weakening of the piston ring in this area means your engine is working less efficiently than it should.

Why is it important to install the top compression ring last?

Final Steps It is important that the ring end gaps are not lined up. This prevents oil flow past the rings. Rings installed in the wrong grooves or the wrong side up can lead to excessive oil consumption and blow-by and possible scuffing of the cylinders. These problems can cause engine failure.

What happens if you put a piston ring upside down?

The gas pressure on the back side of the ring helps seal it against the wall. It won’t work if the ring is installed upside down. The second ring is usually the same as the top ring. It won’t work properly if you mix them up.

How much does it cost to fix worn piston rings?
