DT Spare Parts 4.20657 Valve cover, with gasket
Basically, this part sits right on top of your engine’s valves. Its main job is to protect them, keeping dirt, dust, and water out. It also holds the oil that lubricates the valve train – think of it like a little reservoir right there on top of the engine. And it prevents oil leaks, of course. It's a surprisingly important seal.
It’s a crucial part of the engine itself. Without it, your valve train would be exposed and quickly damaged. It's up there keeping everything running smoothly, preventing a lot of internal wear and tear. It’s a fairly visible part, but people don’t usually think about it until something goes wrong.
Well, if it cracks or the gasket fails, you’ll notice if you have an oil leak—that's the most common symptom. But more than that, if it's compromised, debris can get into the engine, and that’s where things get serious. It acts like a shield, protecting really expensive components. Replacing a valve cover is a lot cheaper than rebuilding an engine. You can find a good selection of these at places like Fixparts Online, and it’s a job a reasonably skilled DIYer can handle, but it does require a little patience. If you ignore a leak for too long, it can lead to bigger problems with lubrication and potentially engine damage.
Next-gen performance: Valve cover (MPN 4.20657) is backed by a 12-month warranty!
