If you own an E46 you know that eventually you’ll have replace your E46 valve cover gasket, if you haven’t already done it.
In this article I’ve put together a similar post to the genuine E46 valve cover article I first wrote on E46valvecover.com.
Topics you’ll find in this article:
Repairpal.com says that valve cover replacements are common around 60,000 miles. Some of the symptoms will include oil drips under the vehicle and burning oil smell from the engine compartment.
If you want to see some of the most common problems on your E46 to watch out for besides a valve cover leak, or if you’re just contemplating buying one, here’s what to expect.
As long as you have all the tools and parts for this repair, it’s estimated not to take more than a couple of hours to do the complete VCG replacement.
It’s best practice if you’re doing an E46 valve cover replacement to just go ahead and do the gasket as well.
Note: It's not uncommon for these plastic covers to crack or warp with time.

It really depends whether you’re buying an aftermarket brand, or the genuine BMW part. Doing it yourself over hiring a mechanic, can be another variable in your cost.
As far as your parts go, your cost will be between $22-58. Again, this is depending on whether you’re going aftermarket over OEM.
I ran an estimate on Repairpal.com for an E46 valve cover replacement and this was the result:
You can obviously save most of this, by just buying the parts yourself and doing it yourself if you have the skill set.
There are a ton of DIY videos out there and I’ll share some pretty good one’s with you that can hold your hand throughout the hole process. Plus, the forums come in handy if you run into any issues.
