A leaking valve cover can do more to ruin a clean engine bay quicker than almost any common problem you are going to have with your 2002. The gaskets on the 2002 are not paper and are not prone to leaks. However, if you start to see a small leak, change your gasket right away before it becomes a big one and causes a mess. The gasket is quick, cheap and easy to replace.

You are looking at one of the most beautiful BMW 2002's engine bays you will ever see because we had the pleasure of working on the Clarion Build's BMW 2002 right after it finished its restoration.

You are looking at one of the most beautiful BMW 2002's engine bays you will ever see because we had the pleasure of working on the Clarion Build's BMW 2002 right after it finished its restoration. While there is nothing you have to move out of the way to get to the valve cover, there are a few things attached to it that you need to remove. Depending on the condition of your vehicle, the year and induction system your vehicle runs and the brackets may vary.

The Clarion Build's BMW 220 has dual Webber side draft carburetors.

The hardware on your motor will determine which tool you need to use.

The hardware on your motor will determine which tool you need to use. Due to the hardware on the Clarion car we had to use a 10mm deep socket to clear everything (red arrow).

If your motor has the spark plug retaining wire clip this is also held in place by one of the valve cover nuts (red arrow).

Clean both mounting surfaces on the head and cover.

Clean both mounting surfaces on the head and cover. Do not use anything metal or sandpaper that could scratch, gouge or make the surfaces uneven.

Install the new gasket and replace the valve cover on the head.
