NICHE GASKET

A gasket is a mechanical seal which fills the space between two or more mating surfaces, generally to prevent leakage from or into the joined objects while under compression.

Some Types of Gaskets:

  • Head gaskets create a seal between the engine block and cylinder head. This seal establishes a proper compression and prevents fluid leaks into the cylinders
  • Base gaskets create a seal between the top-end of your engine and the engine cases. Stop pesky engine oil leaks before they cause permanent damage to your engine.
  • The valve cover is sealed to the upper section of the engine cylinder head by a valve cover gasket. As it passes around the camshafts, rockers, and valves, the gasket stops engine oil from seeping out.

Fit my 2012 perfectly when doing some top end work. Replaced all the factory gaskets perfectly and no signs of any leakage after several hundred miles.

Missing valve cover gasket from set, head gasket does not match (see picture) Only gasket that matched was exhaust and cylinder gaskets. Cylinder gasket has 1/4 inch gap between gasket and cylinder.

I have a 1997 Xplorer 500 and I used all but 2 gaskets. The Cylinder Head gasket wasn't used cause I never took it off. But the Chain Tensioner gasket was too small, not the right size so I had to use gasket maker instead. Giving it 3 stars cause it did state it was for my model. The head gasket is metal which it should be and was a good fit. The rest of gaskets works as expected with typical fabric type material. Head, Cylinder, Exhaust, Cam Cover & Valve Stem Cover gaskets all were good forms. It was just the Chain Tensioner gasket was not right.
