Sinotruk HOWO Turbocharger Oil Return Pipe Assembly (Part No. VG1246110055)

The VG1246110055 Turbocharger Oil Return Pipe Assembly is a critical component in the HOWO parts ecosystem, specifically engineered to handle the high-temperature environment of the Sinotruk WD615 engine.

Technical Specifications

Based on years of experience with Sinotruk engine overhauls, here is what our technicians recommend:

1. Check for Carbon Buildup: During every turbocharger inspection, remove the VG1246110055 pipe and check for "coking" (hardened oil deposits). A restricted return line will blow out your turbo seals.

2. Gasket Replacement: Always use new gaskets when reinstalling the oil return assembly. Reusing old gaskets is the #1 cause of minor leaks that eventually lead to major messes.

3. Correct Torque: Over-tightening the flange bolts can warp the thin pipe base. Always follow the Sinotruk factory torque settings.
