Rear main seal repair

Rislone has introduced a new smaller-bottle version of Concentrated Rear Main Seal Repair. The new concentrated formula provides the same unique blend of polymers, lubricity agents, anti-oxidants and conditioners as the original Rislone Rear Main Seal Repair, but in a much smaller bottle: 500 mL vs. 950 mL.

“Rislone has offered affordable engine treatment solutions for more than 90 years,” says Clay Parks, Rislone vice president of development. “As the cost of some of the non-essential ingredients in our product has increased, we looked at the best ways to keep our price as low as possible for our customers. Reducing the base oil while maintaining the same level of key additives allows us to offer a Concentrated Rear Main Seal Repair that will stop all oil leaks very affordably.”

Persistent engine oil leaks usually can be traced to the vehicle’s rear main seal. Replacing this seal is a labor-intensive job that can cost upwards of $500, but ignoring the leaks can result in even more expensive damage to electrical components, rubber hoses, rubber engine mounts and other parts. Rislone Concentrated Rear Main Seal Repair (p/n 34240) is specially formulated to stop leaks at the rear main seal, and it also works better than a conventional stop leak on all other oil leaks, including those at the timing cover seal, O-rings and other seals and gaskets.

The rear main seal is located between the engine and transmission. Leaks here are usually caused by a combination of normal wear in the crankshaft and seal, and by the drying, hardening, and shrinking of the seal over time. Rislone Concentrated Rear Main Seal Repair restores seal size, flexibility and elasticity. Chemical polymers in the product also fill in gaps and grooves in the crankshaft caused by normal engine wear, and build a protective film around the seal to prevent leaks.

Rislone Concentrated Rear Main Seal repair works with all gasoline and diesel engines that use conventional, high-mileage or synthetic motor oil. One bottle treats four to six litres of oil. Larger systems use one bottle for every five litres of oil capacity.

Like all Rislone products, Rislone Concentrated Rear Main Seal Repair is made in North America.
