DIY Valve Cover Gasket on C320: Need some help
I found DIY instructions for one of the V8 engines for the valve cover gaskets and it looked pretty easy. I've got a quote from an independent shop for $365, so that comes to 4.25 hours and $60 in parts. I don't see how the V8 instructions could take a professional that long to do, so I'm considering doing it myself.
Does anyone have DIY instructions for this on the C320? How long for a moderately skilled amateur? Any obstacles, pitfalls, risks, tricks, necessary tools?
Thanks

I believe the instructions are pretty much the same. I used those instructions to do my c240. Do you know if you need to do the recirculating covers as well? If so, removing the old sealant is a pain and can be very time consuming.

I've changed the valve cover gaskets on '04 C320 (M112 engine). It was very straightforward and relatively easy. Passenger side is super easy since there are no obstructions. On drivers side, you will have to disconnect fuel line because it runs right on top of the valve cover.
While you are changing the valve covers, I recommend you to open and clean engine breathing chambers (they are attached to the valve covers). Valve cover gaskets are around $15 for each side.

By the way, if you need to change spark plugs, it's very easy to access the spark plugs when the valve covers are off (especially on the drivers side).
