* Clean. When cylinder head covers are installed, cover oil ducts with rags. Do not use any sharp-edged tools or abrasive paper as this will damage the sealing surfaces. Oil channels clogged with sealant will damage the engine. Cleaning materials: Loctite 7200 or Loctite 7063 cleaning spray 150 ml (A001986717110).
* Sealant. Apply a 2.0 mm thick bead of sealant (A), observing the bolt holes (arrow). Do not spread the silicone bead. Process sealant within 10 minutes. To avoid leaks, use only the silicone sealant specified in the repair materials - Loctite 5970 sealant (A0039899820)!

For all M112 and M113 gas engines with leaking breather chamber covers on top of engine If you own a 1998 to 2006 Mercedes with a V6 (M112) or a V8 (M113) engine this is one job you will have to deal with at some point. Just pull the top cover off your engine and look. Even cars with low mileage may have oil seeping out the breather covers on the top of the heads. Doing a proper reseal on these covers is not hard but it is tedious if you don't want them to leak again. This is one job if you want it done right you should consider doing it yoursel!!!

Even more so than needing the correct sealant, you will need to make sure the sealing surfaces are ABSOLUTELY clean of any dirt, oil, or moisture BEFORE you apply the new CORRECT sealant. This kit contains supplies and instructions on how to do just that.

Kent removes the right side breather cover on a W220 S500 and takes you through the process step by step.

Removing the cover from the engine Inspecting the sealing surfaces for leaks Intial cleaning for the dirt and old sealant 2nd level cleaning of the oil and grease Tools and supplies to use to avoid damaging the surface of the magnesium parts 3rd level and final deep cleaning Replacement of the original aluminum bolts Cleaning the valve cover long bolts Proper application of the sealant Reason for quick assembly Using a torque wrench for final tightening of the bolts Inspection and final wrap up

The replacement stainless steel bolts in this kit are the correct metric thread and length. Rather than a torx head the bolts had a 5 mm hex head.
