Purpose

   This comprehensive repair kit is designed for overhauling or maintaining BMW N46 engines, addressing common wear issues (e.g., oil leaks, timing chain wear, gasket failures). It restores engine performance, extends lifespan, and ensures OEM-level reliability.

Working Principle

• Sealing & Compression: Gaskets and seals maintain proper compression and prevent fluid/air leaks.

• Timing System Stability: Tensioners and guides ensure precise timing chain alignment, avoiding slippage or damage.

• Lubrication Integrity: Seals retain oil within critical components (e.g., camshafts, crankshaft) to reduce friction.

Compatibility

• Engine Models: Compatible with BMW N46 engines (e.g., N46B20, N46B18).

• Vehicle Applications: Fits select BMW 1 Series (E81/E82/E87/E88), 3 Series (E90/E91/E92/E93), and X1 (E84) models.

• OEM Equivalence: Matches original BMW part specifications (e.g., Genuine BMW 11 12 7 566 383 for head gasket).
