The 300 CDI, 320 CDI, and 350 CDI variants impress with smooth running and performance — but struggle with typical weak points: oil pump wear, bearing bore distortion, and problematic cylinder bores inevitably lead to engine failure without professional repairs. 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 rebuild of the OM642.853 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 all engine speeds and load ranges.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBearing bore alignment\u003c\/strong\u003e — As mileage increases, the crankshaft bearing seats shift in the aluminum engine block of the OM642.853. The result: the main bearings no longer run in true alignment, which leads to increased wear and engine damage. MIK re-hones the bearing bore and permanently secures it in the correct position with hardened shim 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 ensure smooth engine operation and a long lifetime — even under high continuous load.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGray cast iron cylinder liners\u003c\/strong\u003e — Depending on the model year, the OM642 was fitted with different cylinder bores: while the gray cast iron versions are robust, plasma and AluSil coatings tend to develop scoring and compression loss even at relatively low mileage. MIK uses gray cast iron cylinder liners exclusively 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 via our project management app. Live images and detailed reports directly on your smartphone — no black box, just 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 bores\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\u003eCamshaft adjusters \u003cem\u003e(for full rebuild)\u003c\/em\u003e\n\u003c\/li\u003e\n\u003cli\u003eOil spray nozzles\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\u003eBoring \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\u003eOM642.853\u003c\/strong\u003e fits vehicles in the series: \u003cstrong\u003eMercedes Benz 300, 320, 350 CDI\u003c\/strong\u003e.
