Rislone Concentrated Rear Main Seal Repair 500ml

Rislone Concentrated Rear Main Seal Repair 500ml Specifically designed to seal rear main leaks, but also works better than a conventional stop leak on all other leaks. This includes the timing cover seal, cam seals, O-rings and other gaskets. Most rear main seal leaks are caused by a combination of normal wear in the crankshaft & seal and the drying, hardening and shrinking of the main seal. Rislone Concentrated Rear Main Seal Repair restores the seal to like new condition and also contains additives to stop leaks in severely worn seals and crankshafts. 1 bottle treats 4 to 6 L. 500 ml
