- One of the key benefits of the CMR5H spark plug is its ability to improve fuel efficiency. By providing a consistent and strong spark, this spark plug helps to ensure that fuel is burned efficiently in the combustion chamber. This not only helps to reduce emissions but also ensures that you get the most out of every drop of fuel.
Selecting Quality Rubber Valve Cover Gaskets
8 tips to keep in mind when installing or replacing oil seals



The edge of the metal is finely ground after seal manufacture in a centerless grinder to enable an interference fit in the oil seal housing. A slight chamfer on the outer diameter (OD) of the seal is desirable for easy assembly. The sealing lip is prepared by buffing, grinding or cutting away the rubber flash which occurs at the sealing edge. A fine sealing edge creates sufficient pressure on the shaft to minimise spring load, leading to lower friction whilst maintaining effective seal performance. The garter spring plays an important role in the efficiency of the oil seal. If its tension is too high, heat will be generated between the sealing lip and the shaft, and result in rapid wear of the lip. If too low, the spring will be ineffective and the sealing lip will be worn away leading to leakage of the fluid.
