VG1560070046 Complete Oil Return Pipe – Howo/Sitrak Truck Parts

The Complete oil return pipe (OEM VG1560070046) is not just a replacement part—it’s an upgrade. Designed to withstand high thermal stress and vibration, this pipe ensures that oil returns to the sump without flow restriction. Every curve and flange is CNC-formed to match the original Howo/Sitrak blueprint, eliminating installation guesswork.

When you install this component, you protect the turbocharger and crankshaft from oil starvation. The integrated sealing ring and crimped joints prevent leakage, even during cold starts. Trusted by workshop professionals worldwide.

This Complete oil return pipe is manufactured using hydroforming technology, ensuring consistent wall thickness and bend radius. The steel tube is zinc-nickel plated, offering superior corrosion resistance against road salt and engine fluids. The integrated flexible section absorbs vibration, reducing stress on the turbocharger flange.

Every pipe is pressure-tested at 16 bar before packaging. The fitting kit includes new crush washers and bolts, so you have everything for a worry-free replacement. The OEM number VG1560070046 is laser-etched on the pipe for traceability.

Direct fit for Howo A7 (2009–2016), Howo T7H, Sitrak C7H, C9H, and many heavy-duty trucks using the MC11 / MC13 engines. The Complete oil return pipe replaces the original part without any adapter. All mounting holes align perfectly with the engine block and turbocharger return flange.

Installation takes about 90 minutes for a trained mechanic. Simple tools: 13mm and 16mm sockets, torque wrench, and new gaskets (included). Always clean the mating surfaces and apply a thin layer of oil to the O-rings for a smooth assembly.

Each Complete oil return pipe undergoes 100% inspection: dimensional check, weld integrity, and leak test at 1.5x working pressure. We source raw materials from ISO-certified mills. The pipe’s bend radius is controlled within ±1.5° to avoid stress cracking.

This is the same specification used by original equipment suppliers. By choosing this Complete oil return pipe, you eliminate the risk of premature failure caused by thin-walled or misaligned aftermarket pipes.

Heavy-duty trucks operate under relentless conditions—mud, heat, vibration, and extreme loads. The oil return system is often neglected, yet it is vital for engine longevity. The Complete oil return pipe with OEM number VG1560070046 is specifically contoured to navigate tight engine bays while maintaining a straight, unrestricted flow path. Its unique bracket design absorbs chassis flex, preventing metal fatigue. Over 1,200 field tests have confirmed that this pipe outlasts generic alternatives by an average of 80%.

Moreover, the inner surface is micro-finished to reduce turbulent flow, which directly contributes to consistent oil pressure at the main gallery. For fleet operators, using genuine-spec components like VG1560070046 reduces unplanned downtime and lowers total cost of ownership. The pipe’s high-temperature silicone seal remains flexible even after 1,000 thermal cycles from -30°C to 140°C.

Installation pointers: always replace the crush washers—they are single-use. Torque the banjo bolts to 45 Nm. After installation, run the engine for 2 minutes, check for leaks around the crimped joints. The Complete oil return pipe is compatible with synthetic and mineral oils alike. With the correct fitment, you will notice quieter turbo spool and more responsive throttle, as oil cavitation is minimized.

This product is stocked in regional warehouses for fast delivery. Each pipe is individually packaged in a reinforced carton with foam inserts, preventing transit damage. The laser-engraved VG1560070046 marking ensures easy identification during routine maintenance. For workshops, we recommend keeping this part in stock—it fits the most popular Howo and Sitrak models in the market.

To conclude, the Complete oil return pipe (VG1560070046) is not merely a replacement; it’s a reliability upgrade. With its robust construction, precision engineering, and flawless fit, it sets the standard for aftermarket oil return solutions. Order confidently and keep your heavy-duty truck performing at its peak.
