Above all, engine sealing is critical, to keep things sealed and separated within an engine.
With, so many things like, engine oil, engine coolant, vacuum and combustion, it’s a tuff job.
When you think about engine sealing, most people think about, external leaks. But, gaskets and seals also prevent, the entry of, dirt and air, into the engine.
Engine sealing and resealing, is an often overlooked, but is actually, a very important part of maintenance.
So, the best way to care for the gaskets and seals in your engine is, to follow regular maintenance. Consequently, this includes, regular oil and filter changes, engine performance check-ups, and cooling system maintenance.
With engines now lasting as long as 150,000-plus miles, there’s little doubt that gasket technology has advanced. And, have also played, a significant part in the longevity and durability of today’s engines.
So, keeping these engines sealed, creates an even bigger job for engine gaskets and seals.
Todays List Of Engine Sealing Materials Include:
- Neoprene Polychloroprene
- Nitrile (NBR)
- Silicone Rubber
- Multiple Layer Steel (MLS) Head Gasket
Cylinder Head Engine Sealing Technology Advancements
So, the cylinder head gasket is arguably; the most important seal in the engine. Since the very first internal combustion engines were produced, gasket designers have used many materials, to seal the engine.
Some of these include:
- Metal And Asbestos Composite
- Impregnated Fiber
- Graphite Composites
- Multi-Layer Steel (MLS)
Consequently, Today (MLS) gaskets remain the automotive industry’s, preferred method of sealing the cylinder head and block.
Head Gasket Failures
So, with most OEMs choosing to use aluminum; rather than iron cylinder heads, the chance of a gasket failure is increased. Even though aluminum is lighter than iron, it has a much greater, thermal expansion rate. As a result, creating more stress on the head gasket.
