Rear Main Seal Repair

“I just rebuilt my 1966 442 400 cu.in. engine. I was apparently rusty on how to properly install the rear main seal (rope style) and it leaked almost from the get-go. I reluctantly put a quart of your product in my engine. I put over 100 miles on it and it still leaked. I was going to pull the engine and do it right at the end of the summer. Two days later I noticed there was no oil under the car when I pulled out of the garage. I couldn't believe it, the leak stopped. No oil anywhere under the car. UN-believable. ”

“I am now a big fan of your Rear Main Seal Repair. I have a 69 Firebird 400 conv. that I have practically owned since new. It is mostly all original with original drive train, interior and top. It has 105K miles and when I have taken it out of the garage it has left a trail of oil down the driveway. After using your product I was amazed that the leak stopped. I have used other products but nothing helped. I would be glad to endorse your product and if you are interested I can send you pictures of the car. Thanks for a great product. ”

“I have a 1966 Bronco that had a steady rear main leak. I changed the oil pan gasket in hopes this was the problem. I was going to change the rear main seal but it was a one piece type. This means the transmission has to come out to replace the rear main. I was very discouraged after performing this very large job only to find out I had the same problem. A buddy of mine recommended your product and I was a little hesitant of a product like this. To my surprise it worked after driving the vehicle for two day i had no leaks. I was so relieved that I wanted to take the time and thank you for such a great product. This saved me so much time and aggravation as I am a do it yourself-er. ”

“I am an armature car collector and restorer (easy on the restoration). Recently I purchased a 1966 Ford Thunderbird, from the original owner. I drove it from Muncie IN. to New Mexico. After arriving home I started experiencing some problems with the car. Old cars have problems. The rear main seal was leaking. Before paying to have it replaced I used your Rear Main Seal restoration fluid. It worked perfectly! Then, I started getting water in the exhaust. Again, before paying for expensive repairs, I used your head gasket sealer. To my surprise it to worked perfectly! Your products have saved me hundreds of dollars in repairs. Just wanted to say thank you, and I will be recommending your products every chance I get. ”

“I have a 1993 Allante n/s, engine had a oil leak. Cadillac wanted $3,800.00 to fix it so I put a quart of Rear Main Seal Repair in the crank case I think it stop 99%. How long do you think this will last or should I try the same thing again, I also have a 1966 Impala with a leak around the rear main should I trust my luck, hoping to here from you, I have used your product since the 50’s keep up the good work an God bless all of you. ”

“Hi my name is Paul I have a 1983 chaparal boat with a 120 hp io merc cruiser stern drive unit for power. Two weeks ago I noticed bad oil leak coming from the back of the motor. From where the leak was it looked like the oil pan was leaking, so my son and I went and put on a new oil pan gasket, the leak was still there. Not wanting to lose the whole boating season my father said I may want to try your Rear Main sealer. At this time I did not have $1800.00 dollars to repair it, so I tried your sealer. I ran the boat in my yard for about one half hour. I was disappointed as the leak was still there. I was losing a half a quart of oil in this short amount of time, after calling around again for repair prices I decided to try one more time. Being tired and mad I put the rpms from idle to 3000 and went into the house. after about forty minutes I went back out and I was shocked, I saw only a small amount in the drip pan. I could not believe what I saw! After checking the oil and measuring what was lost, I only lost a half of a cup of oil. I am very happy that repair in a bottle does work, Thank you for this product. I know that this is not a permanent fix but it looks like I will be able to use my boat for the rest of the summer season. I am hoping that my local parts store gets more in soon so I can have some on stand by. My son Ryan is a car repair tech and I told him to tell every one that this Rear Main sealer really works. Please do not stop making this product! ”

“I was pleasantly shocked when I used Bar's Leak Rear Main Seal. I had a pretty bad oil leak and was getting tired of my engine smoking from the oil dripping every where. Bar's Leak Rear Main Seal stopped it or good. I highly recommend it!!! ”

“I own a 1987 Ford T-Bird with a lot of miles on it. First bought for my wife to drive, then I drove it for years. It was then passed down to my son. Then my daughter drove it for years. My grandson learned to drive in it. Needless to say, it has a lot of hard miles on it. When no one wanted it anymore, we parked it for a year. I recently decided to put it back on the road. First day I drove it, the rear main seal leaked out four quarts of oil. Brought it home, and parked it again. The next day, I watched "Two Guys Garage", as I do every Sunday. They were advertising sponsor products, and Bar's Leaks Rear Main Seal Repair was one of the featured products. As soon as the show went off, I drove to the nearest auto parts store and bought the product. Put it in right there in the parking lot. I have driven the car for over a week, with no major leakage. I have been an auto and heavy equipment mechanic all my life. I have always repaired problems of this nature, rather than use "mystery oils". However, this product saved me hundreds of dollars to repair a car over twenty years old, with numerous miles on it. Tell Sam and Mr. Fuller thanks for endorsing your product on their show, and thank you for being their sponsor. I have already recommended your products to others.”

“REAR MAIN SEAL REPAIR for President! My experience with car repairs is just about NIL. Anyway in October 2008, I got the oil changed in my wife’s 1995 Toyota Camry. In late November while gassing up the car, I checked the oil and found the oil level more than an inch above the full mark. My limited knowledge told me this was no good. I thought the engine would throw it out somehow... I had the oil changed in early December and put some Engine Oil Stop Leak, NO LUCK. The car was now leaking to say the least. As my wife would pull into the drive way a 20 foot stream of oil drips about 5-6 inches part were clearly visible, oil leaks the size of footballs and basketballs on the driveway and street. A major oil company called and wanted drilling rights for the oil in the driveway. I called a local repair garage and was told the rear main seal was Leaking the engine oil. The stop leak product I used in December with the oil change was a Bar's Leaks product, SO I called Bar's Leaks and was told to get product 1050; Rear Main Seal Repair, it set me back about $10, but thought its a lot better than $1000. This was the COLD weekend we had in JANUARY and the oil level was down more than a quart. On Thursday morning I put in the Rear Main Seal Repair, it is like a like a stop leak, thick and pours slow like molasses and it was COLD outside. I was ready to scrap everything but finally got all the oil in. For product to work requires car to be driven 100 miles, at about 90 miles,,,, guess what NO LEAKS! Drove it for 125 miles,,,, NO LEAKS! I can’t believe this and I want to thank Bar's Leaks for the fine products and especially the two gentlemen for their time and advise and SAVING ME A COUPLE BUCKS. ”

“1050 rear main seal leak repair works! I'm not a stop leak using kind of guy usually. I had a leaky rear main seal on my 95 F-150 5.8L 200,000 miles. I was about to pull the tranny and t-case to put in a new rear main seal but thought, what the heck, I'll try some Bar's Leak. I put it in with my last oil change and it has actually worked. ”

“I just tried Bar's Leaks "Rear Main Seal Repair" to treat a fairly major oil leak in my wife's 98 Chevy Venture with 140,000 miles. It was a little pricey but the claims on the bottle were impressive so I gave it a try. I expected the leak to persist for a few hundred miles and to slow down but not stop which is typical with the usual stop-leak products. Happily, the leak seemed to stop almost immediately and our garage is still dry two weeks later. I have no idea what the long term outlook is for this leak, but I plan to use a bottle of your stuff every oil change and hopefully, the leak is history. Thanks Bars Leaks. ”

“I had to write and tell you that your Rear Main Seal Repair stopped all the oil leaks in my 1989 Ford Country Squire and saved me thousands of dollars. I loved the old car even though it had only 140,000 miles but the oil drips on my garage floor and driveway were unsightly so I was considering a new or rebuilt motor that would cost about $3000, or just junking it and buying a new one. Fortunately last fall I saw your product at a local auto supply store and thought I would try it even over my better judgment. Things like this had never worked for me in the past. Now it is time for another oil change. The oil is about a quart low and there are no drips or leaks. So you can bet a quart of your Rear Main Seal Repair will be added to the oil. Many thanks for selling a product that does just what you say it is supposed to do and saving me thousands of dollars. ”

“Just wanted to drop you a note on how satisfied I am with your new Rear Main oil seal product, it does work very well. I have a 2002 Jeep Grand Cherokee with a 4.7L V-8 and 94K of miles. I change my own oil and noticed oil residue and small amount at bottom of transmission. Having been satisfied with some of your other products, I tried this new oil additive product and checked within 300 miles, the bottom of the transmission was clean & dry with no signs of oil residue. I checked transmission bottom every Saturday after driving 350 miles to/from work each week for the next 3K and it was dry and clean. Your product worked and I will use it every 6K to help keep the main oil seal working as it should. Many thanks for a great product. ”

“Just a note to tell you how pleased I am with your new Rear Main Seal product. After adding your product to my oil, with in 110 miles of driving, my oil leak was repaired. Much like magic!! I have used other Bar's Leak products with great success. But to have your new product correct a bad rear main seal leak, saving me a very expensive repair, was truly amazing! You have a customer for life. I will add a quart of your new Rear Main Seal product with every future oil change; provided I can find it. Your product has not yet reached Dallas, Texas. My NAPA store is trying to get it. Thank you! ”
