The 300 CDI, 320 CDI, and 350 CDI variants impress with smoothness and performance — but they are also plagued by typical weak points: oil pump wear, bearing bore misalignment, and problematic cylinder liners inevitably lead to engine failure without professional repair. MIK Engines eliminates all known problem areas and rebuilds this engine to a standard that clearly exceeds factory quality.\u003c\/p\u003e\n\u003ch2\u003eMIK Upgrades — Why This Engine Lasts Longer\u003c\/h2\u003e\n\u003cp\u003eOur OM642.856 rebuild systematically addresses every known weak point of the OM642 series:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eUpgraded Oil Pump\u003c\/strong\u003e — The factory oil pump in the OM642 delivers too little oil pressure under load and at high engine speeds. This leads to rattling noises, error messages, and, in the worst case, complete engine failure. MIK installs a specially developed high-performance oil pump that reliably maintains oil pressure across the entire RPM and load range.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAlignment of the Bearing Bore\u003c\/strong\u003e — As mileage increases, the crankshaft bearing seats shift in the aluminum engine block of the OM642.856. The result: the main bearings no longer run in perfect alignment, which leads to increased wear and engine damage. MIK line-bores the bearing bore and permanently secures it in the correct position with hardened locating elements.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-Quality Bearing Shells\u003c\/strong\u003e — All bearing components are precisely adjusted to the optimal bearing clearance. High-quality bearing shells guarantee smooth engine operation and a long lifetime — even under high continuous load.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrey Cast Iron Cylinder Liners\u003c\/strong\u003e — Depending on the model year, the OM642 was fitted with different cylinder liners: while the grey cast iron versions are robust, plasma and AluSil coatings tend to develop scoring and compression loss even at low mileage. MIK uses only grey cast iron cylinder liners for maximum wear resistance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLIVE Documentation\u003c\/strong\u003e — Transparency as standard: track the rebuild progress in real time through our project management app. Live images and detailed reports directly on your smartphone — no black box, full control.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eRebuild Scope — Nothing More Is Possible\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eMain bearings, connecting rod bearings, thrust washers\u003c\/li\u003e\n\u003cli\u003ePistons \u003cem\u003e(for full rebuild)\u003c\/em\u003e\n\u003c\/li\u003e\n\u003cli\u003ePiston rings\u003c\/li\u003e\n\u003cli\u003eCylinder liners\u003c\/li\u003e\n\u003cli\u003eConnecting rods\u003c\/li\u003e\n\u003cli\u003eCrankshaft \u003cem\u003e(for full rebuild)\u003c\/em\u003e\n\u003c\/li\u003e\n\u003cli\u003eBearing bore \u003cem\u003e(for full rebuild)\u003c\/em\u003e\n\u003c\/li\u003e\n\u003cli\u003eOil pump\u003c\/li\u003e\n\u003cli\u003eTiming chain kit (complete)\u003c\/li\u003e\n\u003cli\u003eShaft seals\u003c\/li\u003e\n\u003cli\u003eCylinder head gasket \u0026 bolts\u003c\/li\u003e\n\u003cli\u003eSealing surfaces\u003c\/li\u003e\n\u003cli\u003eValves, guides, stem seals\u003c\/li\u003e\n\u003cli\u003eHydraulic lifters, roller rocker arms\u003c\/li\u003e\n\u003cli\u003eCamshafts \u003cem\u003e(for full rebuild)\u003c\/em\u003e\n\u003c\/li\u003e\n\u003cli\u003eCam phasers \u003cem\u003e(for full rebuild)\u003c\/em\u003e\n\u003c\/li\u003e\n\u003cli\u003eOil jets\u003c\/li\u003e\n\u003cli\u003eStud bolts\u003c\/li\u003e\n\u003cli\u003ePulley\u003c\/li\u003e\n\u003cli\u003eOil pan\u003c\/li\u003e\n\u003cli\u003eChain cover\u003c\/li\u003e\n\u003cli\u003eUltrasonic cleaning\u003c\/li\u003e\n\u003cli\u003eSoda blasting \u003cem\u003e(for full rebuild)\u003c\/em\u003e\n\u003c\/li\u003e\n\u003cli\u003eGrinding \u0026 polishing\u003c\/li\u003e\n\u003cli\u003eMilling flat\u003c\/li\u003e\n\u003cli\u003eDrilling \u0026 honing \u003cem\u003e(for full rebuild)\u003c\/em\u003e\n\u003c\/li\u003e\n\u003cli\u003eLIVE documentation via app\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eVehicle compatibility\u003c\/h2\u003e\n\u003cp\u003eThis rebuilt engine with engine code \u003cstrong\u003eOM642.856\u003c\/strong\u003e fits vehicles in the series: \u003cstrong\u003eMercedes Benz 300, 320, 350 CDI\u003c\/strong\u003e.
