What’s the best head gasket sealer?

Some people simply adore their cars, jeeps, SUV’s, etc. However, it is not enough to just polish the paint and to maintain the condition of the upholstery as the true health of your car is determined by the condition of its engine and other internal parts.

A head gasket is a ring-like structure that seals the gap between engine blocks and cylindrical heads of an engine. Its primary role is to block air, engine oils or coolants from entering the combustion chamber.

My friend Phil owned a vintage Bentley which was gifted by his grandfather to his father. He cared for the car but ignored the poor condition of its head gasket. Gradually, he started experiencing engine hiccups and took his car to a vintage car garage who declared the pistons to be rusting due to oil leakage which required an immediate fix.

This was not possible as the company no longer manufactured its spare parts. Could Phil have managed to save his car? Yes, only if he was a little more careful when the leaked oil formed rust marks around the gasket. He could have used a gasket sealer which is used to fix cracks, crevices and other defects of a head gasket.

The head gasket sealers come with different chemical compositions and features. We have carefully examined all of them and present to you the top 5 head gasket sealers which are not only efficient but also very economical. Let’s have a look at these smartly formulated solutions one by one.

Buyer’s Guide

A head gasket sealer is a solution that fixes a head gasket that is damaged or blown away due to constant wearing.

Here are a few symptoms that tell you whether your gasket is functioning properly or not:

Oil leaks – Many times we ignore the oil marks and consider it to be coming out from the valves due to gravity. It is always smart to check your head gasket in such conditions.

Spark plugs – If your spark plug has a dark brown tint to it then it is not a good sign for your head gasket.

Halting engine –It is always better to get your head gasket checked if your engine halts unnecessarily or runs poorly.

Now finally, let’s learn how to use a head gasket sealer:

Step 1: Shake the bottle well to mix the contents of the sealer properly.

Step 2: If there are dirt marks on the system, flush it with an agent and distilled water.

Step 3: Gush water into the radiator but leave some space for pouring in the sealer.

Step 4: Pour adequate amounts of liquid solution in the radiator.

Step 5: Start the car and ensure that the fan speed is at its peak. Keep the heat on and leave the car for some time (approximately 30 minutes).

Step 6: Flush out the sealer and you can drive your vehicle again!

I hope you have liked these pieces of information on head gaskets and their sealers. Do not fret away from using a head gasket sealer as even car experts recommend it for fixing minor defects and cracks.
