This little ring’s job is pretty straightforward. It creates a seal, preventing oil from leaking out of the timing chain tensioner. It's a small rubber piece, but it’s designed to withstand engine heat and oil pressure, keeping everything lubricated where it needs to be. Basically, it keeps the oil in and contaminants out. The timing chain tensioner keeps the timing chain tight. If the chain gets loose, your engine timing gets messed up, and that can lead to all sorts of problems, from poor performance to major engine damage. This seal ring is a crucial part of keeping the tensioner functioning correctly. It ensures the oil pressure builds up inside the tensioner, which is what actually pushes it against the chain to keep it tight. Without a good seal ring, oil will leak out of the tensioner. You’ll notice if it fails because you might start getting engine noise – a rattling or slapping sound, especially on startup. More seriously, if the tensioner loses too much oil, the timing chain can become loose, and that can lead to a really expensive repair. It’s a small part, but it protects a big investment. We often have them in stock at Fixparts Online, and it’s a relatively easy repair if you catch it early. It's a lot cheaper to replace this little ring than to rebuild an engine.
