## Overview

BlueDevil Rear Main Sealer is an 8-ounce liquid formula designed to permanently repair rear main seal leaks by flowing into damaged areas and restoring rubber seals while driving.

## 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: THIS STUFF WORKS!! - 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 desertcart 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.
Review: Worked great for me - Did just what it was supposed to do very well It stopped a full scale flow

### ⭐⭐⭐⭐ So far, so good.
*by F***C on March 4, 2022*

Had a slow oil leak since I bought my 07 tahoe used about a year ago, about a drop or two a day. After a recent oil change, it was leaving a small puddle after every trip. No noticeable leak from up top, the plug or filter, so I assumed the worst, that it would be the pan gasket or rear main. Since I'm in no financial position to pay for any engine work to be done, I gave this stuff a shot. I bought it about two weeks ago and dumped it in. After about a week, I noticed no more leaking, no new spots on my driveway. Hopefully, it stays this way until I can get the motor looked at. I'll update in a month or two if there are any changes. Update 4/11/22: I noticed a few drops on the driveway a few weeks ago, but nothing since. It may have been residual oil that I hadn't cleaned off beforehand. Either way, nothing since. I'll update again next month.
