Here is a clear and concise version of the guide: **Step 1: Disconnect the Battery** * Remove the negative battery cable to prevent any accidental starts. **Step 2: Remove the Intake Manifold** * Follow this guide for removal: [www.pelicanparts.com/techarticles/MINI_R56/85-FUEL-Turbocharged_Engine_Intake_Manifold_Replacement/85-FUEL-Turbocharged_Engine_Intake_Manifold_Replacement.htm] * Tips: + Don't worry about breaking the noise maker from the firewall. + Leave the ducting connected to the throttle housing when removing the manifold. + Use a set of pliers and a long flathead screwdriver to remove the purge solenoid tubing. **Step 3: Check Each Intake Port** * Find which valves are closed by eye or using a mirror. * Stuff a rag into all ports except the one you're working on. * Attach the 3D printed adapter to the engine head and vacuum up any debris. **Step 4: Blast Out Carbon Deposits** * Use walnut shell blasting (100 PSI) for 10 seconds. * Stop occasionally to pick off big chunks of carbon with a metal stick. * Pinch the media feeding hose so that the vacuumed doesn't pull out more walnut shell. **Step 5: Rotate the Engine** * Turn the engine by hand to close other valves. * Remove the passenger wheel and one expanding rivet holding the carpet wheel well liner. * Turn the big bolt CLOCKWISE a few rounds. **Step 6: Clean Remaining Ports** * Use the same process as before to clean any remaining ports. **Step 7: Put Everything Back Together** * Follow the guide for reassembly. * Tighten the intake manifold nuts to 14.7 ft/lbs and the wheel to 100 ft/lbs. **Step 8: Start the Engine** * It may run rough or take a while to turn over at first. * Disconnecting and reconnecting the battery sometimes helps prevent this. * It should run normal after 5 minutes and then much better than before.
