	== Crankcase ventilation ==		== Crankcase ventilation ==
	Crankcase ventilation cover (engine breather cover) is a very common source for oil leaks on Mercedes M112 V6 and M113 V8 engines. When the oil gets on exhaust manifold, it creates smell that can be felt even in the cabin. Resealing the cover is easy way to fix oil leak.

	~~For all~~ M112 and M113 ~~gas~~ engines with leaking breather chamber covers on top of engine		=== Oil leaks ===

Crankcase ventilation cover (engine breather cover) is a very common source for oil leaks on Mercedes M112 V6 and M113 V8 engines. 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. When the oil gets on exhaust manifold, it creates smell that can be felt even in the cabin. Resealing the leaking breather chamber covers on top of engine is easy way to fix oil leak.

			This is the job any owner of a 1998 to 2006 Mercedes with a V6 (M112) or a V8 (M113) engine will have to deal with at some point. 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 yourself!

			=== Clogged ventilation valve ===
			If engine oil is not regularly changed, the ventilation breather valve hole can become clogged which will result in water condensate being accumulated on the top of crankcase and visible on the engine oil cap. Proper cleaning of the milky water residue requires it to be cleaned also from the cylinder head cover. This may be a good moment to also replace the cylinder head cover gaskets.

	==== Sealant ====		==== Sealant ====
			Proper sealant must be used. OEM sealant is Loctite 5970 which is a silicone sealant and cures on exposure to moisture in the air to form a tough rubber gasket. The product is designed primarily for flexible flange sealing. It is ideally used where high vibration or flexing occurs. It is tack-free after just 25 min. The product can be used on machined or cast surfaces, metal, plastic or painted parts.

It must be made sure that the sealing surfaces are ABSOLUTELY clean of any dirt, oil, or moisture BEFORE applying the new sealant. Mercedes instructions recommend using Loctite 7200 to remove old pieces of gasket sealant and Loctite 7063 to prepare surface for the new sealant.

	Removes all types of chemical gaskets eliminating excessive scraping. Softens chemical gaskets quickly. Will not run, even on vertical surfaces. Removes cured chemical gaskets by softening the gasket material on the flanges, avoiding excessive scraping. Dissolves also sealants, adhesives, carbon deposits, and dried oils. Once applied the product foams, preventing run off from the desired location. Application: Protect painted surfaces, as Gasket Remover attacks the paint. Hold can upright and spray from distance of about 20 - 30 cm onto the flange or surface. Allow 10 - 15 minutes to soften the gasket, for silicone gaskets 30 minutes are necessary. Remove gasket with a soft scraper. Wipe the surface with a rag. Repeat procedure if it is necessary.		Removes all types of chemical gaskets eliminating excessive scraping.
