Concentrated Seal Repair for Automotive Leaks

Bar's Leaks 1040 is a concentrated formula designed to seal rear main leaks in automotive applications. It also works on timing cover seals, O-rings, and other gaskets. The product comes in a 16.9 oz brown bottle with a specific gravity of .93 at 60 degrees F. It is intended for vehicle owners addressing external oil leaks.

Verify Leak Type and Compatibility Before Use

Confirm the fluid leak originates from a seal or gasket rather than a cracked component or excessive wear. The formula targets rear main seals, timing covers, and O-rings. Ensure the engine oil is at the correct level before adding the concentrate. This product is not a substitute for mechanical repair on physically damaged parts.

Forms Durable Seal Under Continuous Engine Heat

The concentrated blend circulates through the system to locate and seal leak points during normal operation. It maintains sealing properties under sustained engine temperatures and pressure cycles. The formulation resists breakdown from prolonged exposure to hot oil. Leak reduction typically occurs after the vehicle has been driven for a period.

Questions about this item

What comes in the box and do I need to buy any extra tools or additives to use this 16.9 Oz bottle?

The package contains one 16.9 Oz bottle of concentrated brown seal repair fluid. No extra tools or additives are required; pour directly into the engine oil system.

How do I choose between the different versions or capacities of Bar's Leaks 1040?

This listing is for the single 16.9 Oz concentrated formula, model 1040. No other versions or capacities are offered under this product number.

What does the 0.93 specific gravity at 60 degrees F tell me about how this product behaves once it is in the engine?

The 0.93 specific gravity means the fluid is slightly lighter than water, so it circulates easily with the oil and reaches rear main seals, timing cover seals, O-rings and gaskets to stop leaks.
