BEST piston rings PART DEALS MINIMUM EFFORT!
The piston rings in a vehicle are important because they have three purposes, the main one is to prevent combustion gas from entering the crankcase. Here we explain more.
Piston rings in your vehicle
The piston rings in your vehicle perform three important functions. Firstly, they will help prevent combustion gas from entering the crankcase, and they help in the transfer of heat between the pistons and the cylinder wall. They also prevent oil from the crankcase entering the combustion chamber. While piston rings should deliver many years of sound service, they are liable to wear out and will need replacing when you suspect there is a problem with them. Generally, piston rings are made of materials to help resist wearing out, including having rings made of steel and cast-iron and many are coated to boost their resistance.
Symptoms for failing piston rings
Indeed, the symptoms for failing piston rings include having grey or white exhaust smoke being emitted from the exhaust pipe, a loss of acceleration power and also poor performance from the engine. You may also find that there is excessive oil consumption as well. All of these issues could point to a problem with the piston rings and you must have them fixed. Failure to do so could lead to a fall in oil pressure and a lack of oil in the engine block which could then seize up.
Fitting new piston rings
When it comes to fitting new piston rings, then the crucial measurement is the end gap which is usually measured in thousands of an inch. The ring will be fitted into the piston grooves and the gap is measured with a gauge. There will be recommended limits for the size of this gap, depending on the load of the engine and the bore. The issue is that because metal will expand in rising temperatures, if the gap is too small it may result in the bending or overlapping of the ring when the engine is running under hot conditions, for example, when towing heavy loads or racing. If the gap is set too wide, then there will be an increase in oil consumption, the risk of blow-back gases and poor compression. If you are fitting new piston rings to a used engine then you will need a special ring dodger which is for the top compression ring which will help with compression and also oil consumption without the need to rebuild the cylinder.
It may be a good idea to take your vehicle to a professional if you suspect there may be problems with the piston rings - especially if you have the tell-tale signs of problems such as white smoke coming from the exhaust. The professional will be able to diagnose properly what the issue might be and then carry out the relevant repair.
Searching for piston rings
If you are searching for piston rings, then it's important that you source these from a reputable supplier and that the part complies with the vehicle manufacturer's recommendation and the MorePartz site can help.
