Things You Need to Consider Before Buying a Transfer Case Seal and Gasket Kit
Gaskets and seals are vital. Whenever two surfaces, especially two metal surfaces meet in the car, there is probably a gasket. The gasket fills in the space between two parts that do not fit perfectly together. It prevents gases and liquids from spilling into the wrong places. The following are the things you need to take into account when buying your gaskets and sealing system.
The Need to Purchase a New One
A broken seal can lead to some of the following consequences. First, a broken seal will lead to engine overheat and worst, the car could lose power. Second, a broken seal will destroy the catalytic converter. Similarly, hydrolock or hydrostatic lock may also happen so it is imperative to keep an eye on this one. This causes engine failure and as a consequence, your connecting rods, crankcase, as well as your bearings will bend out of shape. Once this occurs, the worst scenario is that your engine will malfunction and dangerous.
Head Gasket Design and Coating
Take note that head gasket constructions come in two main types: metal and composite. In metal type gasket, construction consists of solid copper, multi-layer steel, or shim steel design. Composite gasket, on the other hand, it consists mainly of thin gasket sheeting that is bonded to a steel core, which includes a fire ring at the cylinder bore.
Putting on a coating or sealer to the head gaskets before installing them can also be considered. Other car owners resort to applying a "copper coat", such as Permatex Copper Spray-A-Gasket or KW Copper Coat. While, in the past, others preferred to spray paint their gaskets before installing them. Basically, this depends on your personal choice. As long as it helps seal up small inadequacies in the head surfaces or in the deck, it will no longer matter whichever you choose. With or without copper spray, it is still acceptable. Also, individual manufacturers usually give recommendations whether it's good to use sealer with their gaskets or not.
Materials Used for its Assembly
There are quite a number of different materials used in the assembly of head gaskets. First is the multiple layers steel. Many modern engines have this multiple layers consist of three layers of hardened steel. Second is solid copper that consists of copper and requires a process called ringing to place pieces of wire around the cylinder. Third is the composite. Composite gaskets are rare because they consist of either graphite or asbestos. In the past, producers were manufacturing composite head gaskets. However, due to their assembly material which contained asbestos, they are becoming gradually rare to find since it is a threat to public health.
Selecting the Perfect Sealing System
Corrosion can be prevented before it gets worse by choosing the right sealing system and its correct combination. One good choice is using the so-called Hylomar. This kind of sealant is perfect for racing applications and can be used in place of a gasket. Another choice is the Shellac. It has heat resistance of up to 300 degrees Fahrenheit and also comes in engine fluid. Your third option are the anaerobic sealers. This is commonly used when there is a limited access to air-drying. You also have the High Tack and the Copper gasket sealant. While the former resists propane, kerosene and diesel, the latter is fast-drying and is heat resistant up to 500 degrees. Form-A Gasket Sealer and the RTV Silicone Sealers are also available. They are also good options to choose from.
