Y10008614 Exhaust Valve is a precision poppet component installed within the cylinder head of JAC YNF40 diesel engine. It coordinates with camshaft and spring assembly to open and close exhaust passages, releasing burned gas out of combustion chamber after power stroke. This aftermarket exhaust valve fixes poor exhaust evacuation, unstable compression and visible exhaust smoke triggered by burnt valve seating face, stem abrasion and valve head deformation under continuous high-temperature impact. Well-controlled exhaust discharge maintains efficient air exchange and protects internal cylinder parts for JAC light trucks and logistics vehicles running frequent start-stop urban distribution and suburban hauling routes.
Product Advantages Made of premium heat-resistant superalloy steel, capable of enduring sustained high exhaust temperature and cyclic thermal shock. The sealing face receives special surfacing treatment to resist ablation and pitting. Smooth finished valve stem minimizes sliding friction inside valve guide. Every exhaust valve is checked for concentricity, length and sealing integrity before packaging, OEM dimension and head contour for accurate valve train rebuild.

FAQ
Q1: What abnormal signs show that exhaust valve face is burnt and leaking?
A1: Reduced cylinder compression, popping sound at exhaust manifold and power drop under heavy load.
Q2: Why is exhaust valve more vulnerable to thermal damage than intake valve?
A2: It directly contacts high-temperature burned gas without cooling from incoming fresh air flow.
Q3: What measurement needs to be adjusted after fitting new exhaust valves?
A3: Re-calibrate valve lash strictly to avoid valve hitting piston or incomplete closure.
Q4: What risk comes with worn valve stem seals alongside damaged exhaust valves?
A4: Lubricating oil will seep into exhaust port and produce persistent blue smoke during operation.
