## Overview

BlueDevil Rear Main Sealer is an 8-ounce, petroleum-free additive designed to restore and permanently seal rear main engine leaks. Compatible with all engine types and oils, it works while you drive, offering a hassle-free, effective solution to prevent oil leaks and extend engine life.

## Description

BlueDevil Rear Main Sealer is a product designed to fix leaks in the rear main seal of an engine. The rear main seal is a critical component of an engine, as it helps to keep the oil inside the engine and prevent it from leaking out. Over time, the seal can become worn or damaged, leading to leaks. Bluedevil Rear Main Sealer is formulated to be a non-particulate sealant that can mix with the engine oil and flow into the damaged areas of the rear main seal, creating a permanent seal. It is designed to work with all types of engine oil and can be used in both gasoline and diesel engines.

Review: As advertised - I used this 2 times now the leak never came back. The first time I used it I was really sceptical about this product still leaking for two days but as I drive along the leak suddenly disappeared. So when I did my oil change I pour another bottle no more leak up to now. I think it does its job kudos to the seller and kudos to bluedevil.

### ⭐⭐⭐⭐⭐ Review
*by R***R on 17 May 2024*

I have a 2009 F150 with over 337,500 miles on the original engine. It developed a persistent rear main seal leak about a year ago. Having called the local dealer, I was quoted labor only of $1,900 to repair this leak. I went on Amazon to see if there might be anything out there that would help. I purchased this Blue Devil pour and go rear main sealer and had it delivered next day, put it in the crankcase as instructed and drove to Ft. Lauderdale (200+ miles roundtrip) So far, after about 400 miles, it looks to me that the leak has stopped. I'm hopeful that it stays stopped and will no longer be a mess on my paver driveway!! I recommend this product based on this outcome.
