What is a Rear Main Seal Leak?

A rear main seal leak can be a serious problem on vehicles. It can cause loss of engine power, excessive smoke and heat, and even possible fire. If left untreated, a rear main seal leak can lead to expensive repairs. Here are some tips on how to stop a rear main seal leak:

1. Check for leaks by turning the wheel all the way anticlockwise and then all the way clockwise. Listen for any unusual noises from the engine bay. If there is a leak, it will show up as an increase in noise levels.

2. Inspect the seals around the rear main Bearing Cap and Piston Ring Compressor (PRC). These seals may have failed due to age or corrosion, leading to leakage. Replace these seals if they are worn or damaged.

3. Check for fluid leaks around the PRC by using a pressure tester or by filling up the Engine Oil Reservoir with water and checking for bubbles inside of it. If there is a leak, it will be evident by an increase in pressure readings.

4. Look for damage to surrounding components due to overheating caused by a leaking PRC sealant or bearing debris entering into the engine oil system. This could include melted rubber gaskets, warped metal parts, and even fires due to accumulation of hot oil and gas fumes
