Classic Car & Hot Rod Engine Products

Classic cars and hot rods carry historical significance and aesthetic appeal that make them worth preserving. If you’re lucky enough to own one, you know driving a classic car and showing it off is the best part. However, as many classic car collectors know, leaking is part of the deal. Older technology is awesome on many levels, but it comes with its own set of problems.

Why Do Classic Cars & Hot Rods Experience So Many Leaks?

The short answer to this question is that materials age and wear down over time, and older engine technology isn’t as advanced as what we see today. Seals and hoses often cause leaks in classic cars with cracks and poor connections. Because these components are typically made of rubber and older, more vulnerable materials, they’re open to a unique kind of damage and deterioration. Rubber loses its flexibility over time, especially when exposed to heat, such as the heat of an engine.

What Types of Leaks Are Common for Classic Cars and Hot Rods?

Like newer vehicles, classic cars and hot rods can experience many kinds of leaks. However, some types of leaks are more common in classic cars:

By examining the color and location of the fluid, you may be able to diagnose the leak yourself, especially if you know a thing or two about cars, as many classic car enthusiasts do. But figuring out exactly what’s causing the leak — and how to fix it — can still be challenging. If you need help diagnosing or stopping a classic car leak, Bar’s Leaks is here to help!

Why Use Our Classic Car Engine Products?

When your hot rod or classic car is leaking fluid, traditional wisdom suggests you have two options — you can either replace the component or system responsible or continue to replace the fluids. If you have a slow leak, you might feel comfortable keeping an eye on it and replacing the fluids occasionally. But for substantial leaks, this can quickly become expensive.

Replacement hot rod engine products can also cost more than you’re willing to pay. They can take time, too, especially if you want to replace the offending piece with a good OEM part. That’s why we’re proud to offer a third option for stopping leaks.

Our classic car stop leak products cost less than replacements and fix many leaks permanently. Our classic car engine products can stop pesky oil leaks with a range of causes and condition your system at the same time, restoring seal flexibility and elasticity to prevent future problems. We also offer classic car cooling system products, transmissions stop leak products and other repair fluids.
