High Strength Engine Valve Cover Assembly F4J16-1003050 Fit Chery Tiggo7 Tiggo8

Manufactured strictly based on F4J16 engine OEM drawing data. All spark plug holes, bolt hole positions, PCV vent ports and flange sealing planes match original cylinder head perfectly. Complete plug-and-play replacement without grinding or trimming, fully consistent with assembly positioning logic of original vehicles.

The whole housing adopts PA66 nylon reinforced with 30% glass fiber. Outstanding heat resistance, oil corrosion resistance and anti-deformation capacity. It will not warp or bulge under long-term 120℃ high-temperature engine compartment environment, solving the common aging deformation oil leakage problem of ordinary plastic valve covers.

Built-in multi-stage labyrinth flow channel inside the cover, which can fully separate oil mist from crankcase waste gas. Effectively reduce engine oil consumption, avoid carbon deposit blockage of intake pipeline, and maintain stable internal pressure of valve chamber all the time.

Equipped with integrated molded fluororubber sealing ring, featuring ultra-wide compression surface and balanced rebound elasticity. Uniform stress distribution after bolt locking, thoroughly block engine oil seepage along flange gaps, realize long-term leak-free operation.

Thickened crisscross reinforcing ribs are designed on the outer wall of the cover to improve overall structural rigidity. Effectively absorb engine operation resonance vibration, reduce noise transmission and prevent gasket loosening caused by long-term vibration.

Valve cover shell, oil-gas separation baffle and sealing gasket are pre-assembled as a whole set. Repair and replacement can be finished in one step, no separate matching of sealing accessories required, greatly saving maintenance time cost.
