This little cap’s job is pretty straightforward – it seals the end of the camshaft. It keeps oil and dirt from getting into the camshaft, and more importantly, it keeps the oil inside where it needs to be for lubrication. It’s usually a simple press – fit part, kind of like a stopper, but it needs to be secure. It’s part of the whole valve train system, which is how your engine breathes. The camshaft itself controls when the valves open and close. This cap protects the end of that camshaft, which is a critical component. Without it sealed, you risk losing oil pressure in that area, and that affects how the whole engine runs. Losing oil up there isn’t good. It can cause wear on the camshaft and the valve train, leading to noisy operation or even engine damage over time. You’ll notice if one’s missing or damaged because you might see an oil leak, or you might hear some ticking or tapping sounds. It’s a small part, but it does a big job protecting a pretty expensive component. We stock a lot of these at Fixparts Online, and they’re usually an easy fix if you find a problem. It's much cheaper to replace this cap than to deal with camshaft issues down the road, believe me. A warranty you can count on: Sealing Cap (MPN 078103113E) has a 12-month guarantee!
