Mercedes-Benz W203 C-Class Valve Cover Gasket Replacement

If you have noticed that your valve covers are filthy with oil there is a very good chance the gaskets are going bad. This is a very common problem with Mercedes C320s but not to worry, repairing them is not that difficult and this article will walk you through the steps. You are going to have to remove the engine air ducts and covers to get access to them. Remove each duct by compressing them towards the engine and slipping them off the air inlet. With the ducts off remove the front engine cover. It pulls up and away from the engine. The cover is held on by five clips and will easily come off with hand pressure. Next, you will need to remove the main engine cover that also houses the air filters. It is held on by four pressure clips. You can see the two at the front of the engine, to remove the housing lift it at the front of the engine and once the front clips release the rears (which you can not see) will release as well. We are going to begin with the right side covers. You will be able to see the valve covers on top of the heads, they hold the coils. Disconnect the individual wiring harnesses going to each coil, there are three of them. They simply squeeze in and pull out of the coil. Next, remove the crankcase breather hose from the breather cover. If the hose is fairly new it should slide off. If the hose is original or old there is a very good chance it is dry and brittle and you are going to damage it and need to replace it. Do yourself a favor and order new hoses before you start this job. Use a T-30 Torx and remove the bolts holding the coil packs in place. With the bolts gone you can just swing the coils out of the way. You do not need to remove the wires and boots from the plugs but now is a good time to take them off and clean them. The boots can be very tricky to remove and will take a little patience, especially the ones at the rear of the motor. The boots are on quite snug and you will need to use a 17mm open end wrench to place over the end of the boot and using the valve cover gently pry the boots off. If you want to make the job very easy Pelican sells the Hazet tool that is basically a specially bend open ended 17mm wrench that makes getting the boots off a ease and you can use them to help seat the boots when you reinstall them. Note: NEVER try and remove the boots by pulling on the wires, you will only end up ripping the wires from the boots! Remember the while the coils are interchangeable the wires from each coil must go to the appropriate plug. With the coil mounted on the cover the "A" wire always goes to the forward plug. Next you will need to use an E10 Torx driver and remove the 9 bolts holding the cover on. You may have to wiggle the covers around to get the seal to break loose to remove the cover. Do not hit the cover or try and jam a screwdriver between the valve cover and head as this can damage both causing them to leak even more. Remove the old gasket and clean the area. You do not have to clean every where (unless you are going for a concourse look) but you do need to clean off all of the old gasket and clean any areas that mate. Install the new gasket into the valve cover and reinstall on the head making sure it sits flush and does not fall out, especially on the rear. The left side of the engine is similar with the exception of two breather hoses and the top rear bolt has a mount attached to it, other than that the procedure is the same. Installation is the reverse of removal. Read the Full Article: https://www.pelicanparts.com/techarti...
