🔧 Seal your engine’s valve train with genuine SANY parts – the OEM cylinder head cover assembly 160102130004A048 (Cylinder Head Cover Group). This precision‑moulded cover encapsulates the overhead camshaft, rocker arms, and injector wiring, preventing oil mist escape and external contamination. The 160102130004A048 head cover is manufactured from high‑temperature reinforced plastic (PA66‑GF35) with an integrated oil separator baffle and rubber edge gasket. It seals tightly against the cylinder head using ten M6 bolts, maintaining crankcase pressure control and reducing emissions. When replacing a warped or cracked original cover, this genuine SANY component guarantees perfect fitment, correct PCV calibration, and leak‑free service for thousands of operating hours.
The 160102130004A048 Cylinder Head Cover Group is an essential top‑end component that seals the valve train area of SANY D12 and D09 heavy‑duty diesel engines. It covers the overhead camshaft, rocker arms, valve springs, and injector wiring harness, keeping engine oil inside while preventing dust, water, and abrasive particles from entering the lubrication circuit.
Manufactured from high‑performance glass‑fiber reinforced polyamide PA66‑GF35, this cover offers exceptional dimensional stability at continuous operating temperatures up to 150°C. The material resists chemical attack from engine oil and coolant vapors, and its low thermal expansion matches the aluminum cylinder head, maintaining consistent gasket compression over thermal cycles.
The cover integrates a positive crankcase ventilation (PCV) oil separator baffle that reduces oil mist carryover into the intake system. This baffle uses a labyrinth path to condense oil droplets, which then drain back through integrated return passages. By lowering oil consumption and preventing intake valve coking, the 160102130004A048 contributes to lower emissions and longer DPF life in Euro V/VI compliant machines.
A perimeter silicone rubber gasket is pre‑molded into the cover’s lower flange, providing a leak‑tight seal without the need for separate gaskets or sealants. The gasket features anti‑extrusion stops to prevent squeezing out during bolt tightening. The recommended gasket compression is achieved by torquing the ten M6 mounting bolts to 10 N·m in a cross‑pattern sequence.
Why the 160102130004A048 Cylinder Head Cover Group Provides Reliable Sealing
High‑Temperature Material
PA66‑GF35 withstands continuous under‑hood temperatures up to 150°C, far exceeding standard polypropylene covers. Resists oil degradation and warpage that cause external oil leaks.
Integrated Oil Separator
The built‑in labyrinth baffle effectively removes oil mist from blow‑by gases. This reduces oil carryover into the turbocharger and charge air cooler, protecting aftertreatment components.
Pre‑molded Silicone Gasket
The fluorosilicone edge seal maintains flexibility from -40°C to +180°C. It does not harden or crack, eliminating the need for messy liquid gasket applications.
Genuine SANY Fitment
The 160102130004A048 exactly matches the cylinder head bolt pattern, PCV port location, and injector cutout geometry. Aftermarket covers often have misaligned holes that cause gasket leaks.
Technical Specifications – Cylinder Head Cover Group 160102130004A048
Advanced PCV integration and emission control: The 160102130004A048 cylinder head cover incorporates a closed‑loop crankcase ventilation system. Blow‑by gases from the engine’s combustion chambers enter the cover through internal galleries, then pass through a multi‑stage labyrinth baffle. The oil mist impinges on the baffle walls, coalesces, and drains back through one‑way check valves into the camshaft valley. The cleaned gases exit through the PCV port to the intake manifold, maintaining negative pressure in the crankcase and reducing oil sludge formation. This system is critical for meeting Euro III/V and China VI emission standards.
The cover also provides sound damping – the thick composite material significantly reduces mechanical noise from the valve train. Compared to stamped steel covers, the PA66‑GF35 construction reduces airborne noise by 3‑4 dBA, contributing to a quieter operator environment. For engines requiring additional silencing, the cover has mounting bosses for an acoustic foam overlay (accessory part).
Installation of the 160102130004A048 cylinder head cover requires cleaning both the cover and cylinder head mating surfaces. Remove any old gasket residue with a plastic scraper (avoid metal tools that could scratch the head). Inspect the integrated rubber gasket for any nicks or tears – if damaged, the cover must be replaced, as the gasket is not sold separately.
Position the cover onto the cylinder head, ensuring the PCV port aligns with the breather hose connection. Insert the ten M6 bolts through the cover flanges, and finger‑tighten them. Using a torque wrench, tighten in a cross‑pattern sequence (starting from the center outward) to final torque of 10 N·m. Overtightening will compress the rubber gasket beyond its elastic limit and may crack the plastic cover. Undertightening will cause oil weeping along the flange.
After installation, reattach the PCV breather hose and ensure it is not kinked. The oil filler cap (included in the group) should seal with an audible click. Start the engine and check for oil leaks around the perimeter – if any appear, re‑torque the bolts to 10 N·m. For engines equipped with a crankcase pressure sensor, ensure the sensor is transferred to the new cover using the original O‑ring.
The cover also houses the oil dipstick guide tube and oil fill neck. When installing, lubricate the dipstick guide O‑ring with engine oil to prevent damage. Over time, the rubber gasket may take a compression set, but SANY recommends replacing the entire cover only when cracks or physical damage occur – not as a routine maintenance item. Typical service life exceeds 10,000 hours in normal operating conditions.

Common failure modes and preventive maintenance: The most frequent issue with cylinder head covers is warpage due to over‑torquing or exposure to extreme heat after coolant loss. A warped cover will allow oil seepage, especially at the corners. Additionally, the PCV baffle can become clogged with sludge in engines with extended oil change intervals, causing excessive crankcase pressure that pushes oil past seals. Inspect the 160102130004A048 every 2,000 hours for signs of cracking around bolt bosses or oil stains. Always replace the cover if any crack is longer than 10 mm. Clean the PCV passages with brake cleaner and compressed air during valve adjustments.
Aftermarket copies often use inferior ABS plastic that becomes brittle after 1,000 hours, leading to sudden cracking and oil spray onto hot exhaust manifolds – a fire hazard. Genuine SANY covers are flame‑retardant certified (UL94 V‑0) and pass a 300‑hour thermal aging test at 150°C. The glass fiber reinforcement also prevents distortion during engine braking cycles. For maximum reliability, always source the 160102130004A048 from authorised SANY distributors.
To verify authenticity, check the moulded SANY logo and the OEM number 160102130004A048 on the underside of the cover (visible when removed). Genuine covers also have a date wheel and cavity number near the oil fill neck. The surface should be smooth, without sink marks or flash. Counterfeit parts often have rough textures, mismatched colors, and missing part numbers.
When ordering a replacement, confirm your engine serial number to receive the correct version. Early D12 engines used a cover with a separate oil separator box; later models (after 2016) integrate the separator as described. The 160102130004A048 supersedes all previous variations (160102130004A032, A041) and is backward‑compatible with a simple adapter hose. For Euro V engines equipped with a crankcase pressure sensor, the cover includes a dedicated sensor boss with O‑ring groove. If your engine has a closed crankcase ventilation (CCV) filter, the PCV port orientation matches the filter housing exactly.
