Rear Main Seal Replacement Tips

Replacing a leaking or worn out rear main seal can be a tricky job, but with some preparation and knowledge it can be done quickly and easily. Before beginning, its important to have all of the necessary tools and parts on hand: new rear main seal, block plate (if required), torque wrench, vice grips, RTV sealant (or gasket), clean rags, and some type of lubricant (mineral or synthetic).

Once all necessary parts are gathered together, making sure that everything is properly cleaned before beginning will help ensure a successful installation. Using either mineral or synthetic oil as a lubricant on the outer edge of the new seal will help ensure that it slides into place without damaging it or causing additional leaks down the line.

Differences Between RTV Sealant and Gaskets

When replacing a leaking or worn out rear main seal its important to know what type of material should be used for sealing: RTV sealant or gasket? RTV (room temperature vulcanizing) sealant is a silicone-based material that cures at room temperature after being applied between two surfaces that need to be sealed together. It provides superior sealing properties compared to traditional gaskets because there are no gaps between mating surfaces which could possibly cause leaks over time.
Gaskets are made from sheets of flexible material such as metal or rubber which provide an airtight barrier between two surfaces when properly sealed with bolts or other fasteners. Gaskets are usually preferred over RTV sealants in high pressure applications because they provide superior compression without breaking down over time like many RTV products do when exposed to extreme temperatures and pressures.

Advantages And Disadvantages Of Using Different Oils During Installation

When replacing a leaking or worn out rear main seal there are several different types of oils that can be used during installation: synthetic oil vs mineral oil; high mileage oil vs regular motor oil; etc Each type has its advantages and disadvantages so choosing which one to use depends on your specific needs and situation. Synthetic oils typically offer better lubrication than mineral oils due to their higher viscosity index; however they tend to cost more than traditional mineral oils so if cost is an issue then this may not be your best option. High mileage oils can also provide superior performance but they may not be necessary for vehicles with lower mileage since these formulations typically contain additives that help reduce engine wear during long periods of operation which could lead to higher maintenance costs down the line if not needed in your situation. Finally regular motor oils provide good basic lubrication but may not offer all of the benefits associated with synthetics or high mileage oils so depending on your needs this may be your best option as well.
