My Buying Guide on Best Rear Main Sealer
As a car enthusiast, I have faced my fair share of engine leaks and one of the most common and frustrating ones is a rear main seal leak. This type of leak can result in oil puddles under your car and can be quite costly to fix if taken to a mechanic. After trying out various products, I have compiled a buying guide for the best rear main sealer to help you make an informed decision.
What is a Rear Main Sealer?
A rear main sealer is a product specifically designed to repair leaks in the rear main seal of your engine. It comes in liquid form and contains special additives that can swell and soften the seal, allowing it to expand and fill any gaps or cracks.
Factors to Consider
Before purchasing a rear main sealer, there are certain factors that you should consider to ensure you get the best product for your needs.
Type of Sealant
There are two types of sealants available – solvent-based and non-solvent based. Solvent-based sealants are more aggressive and can cause damage to rubber seals if used frequently. Non-solvent based sealants are considered safer for your engine but may not be as effective in sealing leaks.
Compatibility
It is crucial to check if the rear main sealer is compatible with your engine type and oil type. Some sealers may not work well with certain types of engines or oils, so make sure to read the product specifications carefully before purchasing.
Quality
Investing in a high-quality rear main sealer will save you from future headaches. Look for reputable brands that have been tried and tested by other car owners. You can also read reviews online or ask for recommendations from fellow car enthusiasts.
Ease of Application
Some sealers may require you to drain your engine oil and replace it with the sealer, while others can be added directly to the existing oil. Consider your comfort level with the application process and choose a product that suits your needs.
