Does Flex Seal Stop Engine Leaks?

Car engine is the backbone of the vehicle. Significance of a car engine is due to its ability to transfer heat from burning gas to the force which runs on the road. Car engines wear out with the passage of time because of the mileage covered and wear or tear in the engine. Many sell their cars to buy a new car with optimal engine operation. Buying a new car would not be possible for everyone, which is why engine rebuild comes into the play. Classic car engine rebuilders would make used engine gas mileage and internal engine workings better than brand new cars. After engine rebuild your vehicle would help in saving engine energy with proper car maintenance and drivability. 

What is a Flex seal?

Flex seal is a dark dense watertight material which is used to stop to coat, seal and protect almost anything by adhering to the required spot such as cracks, and holes. American based brand founded in 2011 by adhesive bonding products company in Florida. Additionally, flex seal is a black thick and durable, rubberised liquid coating. 

Flex seal is used for many purposes such as blocking out the water, preventing rust, air or moisture by forming the rubberised surface once it gets dry.

There are various forms of flex seal such as flex tape, flex seal liquid, flex glue, and flex paste employed for relevant intents.

Flex Tape 

Flex tape can immediately bond, patch and seal anything due to its super strong waterproof adhesive binding.

Flex Seal Liquid

Flex seal liquid could brush, dip and roll or pour to cover larger areas due to its thick rubberised liquid which starts as thick liquid and dries into watertight coating.

Flex Glue

Flex glue could instantly grab and hold to the surface, due to its strong waterproof adhesive.

Flex Paste

Flex Paste could fill large gaps, holes and cracks by its super thick rubberized paste which can spread in any shape.

Does Flex Seal Stop Engine Leaks?

Flex seal would be an effective adhesive for, masonry, fabric, glass, plastic, aluminium, porcelain, dry wall, wood, metal, tile, concrete, cement, some vinyl and rubber and other. But it would not be a friendly adhesive to diesel, gas or petroleum any hot coolant would not be benefit by flex seal.

Similarly, flex seals would not be able to stop the engine leaks in any shape or form. Flex seal is good for stopping water leaks, but it could not fix anything involving petroleum, oil or diesel. In the beginning flex seals might seem to stop the engine oil for a matter of a few seconds or minutes but in the long-term within an hour the situation might get worse. Engine oil might start to overflow, hence breaking the flex seal with zero results. Because it could not stand heat and petroleum or diesel which lies at the heart of engine oil. 

Most importantly, oil leakage might stop for a little time by causing the rubber to become soft or by swelling the dried flex seal on an engine oil. 

Consequently, there is no truth of flex seal successfully used for stopping engine oil leakage systems, however it would be desirable for retaining the water system stoppage. 

Take away

Flex seal is a powerful watertight rubberised adhesive used for multiple purposes. But accomplishing the feat of engine oil leak stoppage would be impossible to achieve with flex seal.
