Installation Guide (Step-by-Step)
1. Pre-installation Checks
- Flush engine oil & replace filter
- Check oil feed/return lines for blockage
- Inspect air filter & intake pipes
- Ensure no debris remains in the exhaust manifold
2. Turbo Installation Steps
- Remove old turbo and clean mounting surfaces
- Install new gaskets and fit the RHG6 turbo
- Connect oil feed & return lines
- Tighten bolts according to OEM torque specs
- Fill turbo oil inlet with clean engine oil (priming)
- Start engine and idle for 3–5 minutes
- Inspect for oil, air, or exhaust leaks
3. Break-in Procedure
Avoid full load for the first 15–20 minutes to allow oil circulation.
Troubleshooting Guide
| Issue | Possible Cause | Recommended Solution |
|---|---|---|
| Black smoke | Low boost | Check intercooler & pipes |
| Whistling sound | Air leakage | Tighten clamps / replace hoses |
| Oil leakage | Blocked return line | Clean or replace line |
