Engine vent hose T2H1418 Positive crankcase ventilation hose for Jaguar Land Rover Reservoir hose 

Product Description:

Crankcase breather hose

OE NO.:   T2H1418   LR035629

Applicable vehicle type: For Land Rover

Engine Vent Hose (also commonly referred to as Crankcase Breather Hose/PCV Hose) is a core component of the engine crankcase ventilation (PCV) and emission system. It is responsible for diverting crankcase blow-by gases and introducing them into the intake manifold for secondary combustion. This function balances crankcase pressure, prevents oil leakage, and avoids excessive emissions. The core material is oil-resistant and heat-resistant flexible material, which is suitable for complex working conditions in the engine compartment.

Common Faults and Symptoms

• Ageing and Cracking / Hardening: High temperatures and oil vapour cause surface cracking, bending, and whitening, leading to oil vapour leakage with oil stains / crystallisation at the joint.
• Collapsing / Blockage: Detachment of the inner rubber layer or accumulation of impurities impedes ventilation, increasing crankcase pressure and causing abnormal oil consumption / blue smoke emission.
• Joint Leakage: Aged sealing lips or loosened clamps permit oil vapour leakage, accompanied by unstable idling / emissions exceeding standards.
• Check Valve Failure: Sticking / damaged valve plates cause backflow of exhaust gases, resulting in oil emulsification / engine vibration.
• Detachment / Fracture: Improper installation or failure of reinforcement layers causes severe leakage, potentially leading to engine stalling at idle.
