BlueDevil Rear Main Sealer from BlueDevil Products is a guaranteed permanent fix for leaks.

Its special chemistry restores seals to their original size and flexibility.

Chemical molecules in the sealer fill over-stretched space between crankshaft grooves while conditioning the seal as preventive maintenance against future leaks.

The rear main seal is located between the engine and transmission.

These leaks are typically caused by a combination of normal wear in the crankshaft and seal, and by the decaying of the seal over years.

BlueDevil Rear Main Sealer seals better than average stop leaks on rear main seals and other engine oil leaks.

One bottle treats up to an 8-quart capacity.
