How to Stop a Transmission Leak

Stopping a transmission leak sounds like a complicated task. Many car owners think that a transmission fluid leak automatically means an expensive and costly visit to the mechanic. Thankfully, there’s a much faster and more affordable solution. At Bar’s Leak, we offer a range of industry-proven transmission leak repair products that are designed to make quick work of stopping your transmission fluid leaks, so you can get back on the road. We know – we’ve been in the leak business for over 70 years.

Transmission leaks can come from several places:

  • Leaking gaskets or seals (including transmission fluid pan)
  • Transmission cooler or cooling line leaks
  • A hole or puncture in your transmission casing

Why do Transmissions Leak

Your automatic transmission has several different seals designed to keep your transmission fluid inside your transmission. If any of these seals fail, they allow transmission fluid to leak. A low transmission fluid level can quickly become a major problem if you drive without enough fluid. Because of this, it is important to watch for transmission fluid leaks and repair the problem as soon as you detect it. Trust us, we’ve talked to dozens of customers who’ve let a transmission leak linger for too long.

Leaking transmission seals can occur for several reasons: Read More

Will Stop Leak Products Damage My Car?

“Stop leak” tends to be a bad word in the automotive industry. Why? For three reasons:

  1. There are inferior products out there that drag down the entire category as a whole, and
  2. There are instances in which the product was installed improperly, or into problematic conditions (dirty or partially-clogged cooling systems, in particular)
  3. The mechanical damage to the car is so bad that no chemical tool can fix it. In these cases, a customer tries a stop leak product, it doesn’t work, and proclaims it useless and ineffective.

Taking these point by point:

  1. Our products have been, and continue to be, used in OEM applications. Brand new cars get our stuff installed at time of manufacture. Think about that. Our technology is also used in military and commercial applications. Like so many other product categories out there, there’s stuff that’s good and proven effective and has had long market longevity, and there’s stuff that’s quite a step down from that.
  2. The #1 problem we see is that folks install products like ours into cooling systems that are dirty or already partially obstructed. This, reliably, will lead to further clogging, and it’s why we specifically say our products should be installed into a clean environment.
  3. A chemical tool has a window of opportunity relative to the severity of the system damage. That is, if the leak is minor to moderate, we stand a good chance of being able to fix it. If the leak is too far gone, or too acute, then there’s a very good chance we WON’T be able to fix it, and we will tell customers that right up front (we have a whole customer service/QA team who will chat with you about any problem you’re having). That’s what a lot of people don’t understand. Our tech is a good intervention protocol if the leak hasn’t progressed to the point where a full physical fix is necessary.

So what about the objection “just do it right and fix it mechanically?” We’ll address that too.

A full physical (hard part) repair, obviously, is an ideal option. Problem is, many customers cannot afford the cost or downtime of a physical repair, OR their car isn’t worth the investment of a physical repair. In these cases, the customer is faced with a real dilemma: my car is broken, it needs to be fixed, I can’t afford the cost or to have my car laid up in a shop, and I certainly don’t want to be looking for another car. What to do?

That’s where we come in.

Why Does a Manual Transmission Leak?

1420

The fluid in a manual transmission is responsible for lubricating your gears. Metal-on-metal contact when fluid is missing causes wear, and a manual transmission run without adequate oil will damage quickly. Once your transmission is damaged, the only solution is to have it rebuilt or replaced, which is a costly and lengthy proposition. In the case of older vehicles, the cost of replacing a transmission or even simply physically repairing a leak can mean it’s not economically feasible.

If you have a manual transmission fluid leak and want to avoid costly repairs, you’ll be glad to know that at Bar’s Leaks, we have fast, affordable solutions that have been proven over and over again. Let’s look at why a manual transmission can leak, and what you can do to repair it before it becomes a major problem: Read More

Bar’s Leaks® Professional Main Seal™ Motor Oil Leak Repair (MS-1) Quickly Stops Oil Leaks in High-Mileage Vehicles

Professional-grade synthetic formula stops all oil leaks without degrading motor oil

We talk to customers all the time about this. Literally every day.

Oil leaks on older, high-mileage vehicles are usually the result of aging seals and gaskets that are losing the ability to keep oil from seeping out of the engine. Unfortunately for the owners of these vehicles, finding the cause of the leak and then replacing the bad seal or gasket is a time-consuming and expensive job. For those who can’t afford a mechanical repair, Bar’s Leaks has an inexpensive solution. New Bar’s Leaks Professional Main Seal Motor Oil Leak Repair (P/N MS-1) is a high-tech synthetic blend of the best seal restorer additives and polymers to stop all engine oil leaks, guaranteed. It’s the most powerful oil leak repair solution on the market anywhere.

Here’s the root cause: oil leaks commonly occur as engine seals harden and shrink from the plasticizers being removed over time, and as the miles add up. Extended storage (like winter or seasonal storage) can also cause drying and hardening of seals, leading to shrinking and cracking, and consequently leaking. Other oil stop leaks on the market can stop some leaks, but not all of them. Some may even degrade the motor oil, which is the last thing you want.

“Bar’s Leaks Main Seal Motor Oil Leak Repair is a top-of-the-line, commercial-grade product designed to repair any oil leak in just one dose,” says Clay Parks, vice president of development for Bar’s Leaks. “It is without a doubt the best oil stop leak money can buy. We’re so confident in this product, that we back it with a limited lifetime warranty. Plus, because it’s a synthetic blend, Main Seal Motor Oil Leak Repair won’t degrade the engine’s oil.”

Bar’s Leaks Main Seal Motor Oil Leak Repair works in two ways to solve engine oil leaks originating at the rear or front main seal, as well as camshaft, crankshaft and timing cover seals:

  1. A specially engineered seal-rejuvenating additive restores seal size, flexibility and elasticity lost due to engine heat, age and high mileage.
  2. An advanced seal polymer additive package works by building a polymeric film around the seal to help prevent excess oil from bypassing the seal during normal engine operation.

Bar’s Leaks Main Seal Motor Oil Leak Repair is proven safe to use in all gasoline, diesel, turbocharged and racing engines. It works with all types of motor oil, including regular petroleum, high mileage, synthetic blends and fully synthetic. One quart bottle treats oil capacity from 5 to 7 quarts, and can easily replace a quart of oil when needed or during an oil change.
