TIAGO

1.05L REVOTORQ ENGINE 14 engine and allow it to idle for a period to establish full oil circulation and pressure before operating at higher speeds.  Avoid long periods of engine idling. The combination of low-pressures in the turbine and compressor and low turbocharger shaft rotation speed may lead to oil and blow-by gas to seep past the seal into the turbine or the compressor. Maintenance Recommendations:  Turbochargers and boost pressure control valves do not require any special maintenance. However check the boost pressure pipe for its proper fitment, damage, wither etc.  Specified engine oil and the oil filter should be used and should be changed regularly in accordance with the engine manufacturer's recommendations.  Regular maintenance of air intake system i.e. air filter elements cleaning / replacement in accordance with the engine manufacturer's instructions. Clogged air cleaner will restrict the airflow at the turbocharger inlet. This may lead to high exhaust smoke and will also result in seepage of oil from turbocharger into the air intake system.  Checks have to be made on oil feed pipes, return pipes, air intake and exhaust piping for leakages, restriction. The connections and joints should be checked to ensure that they are still tight and no damage has occurred.  Check the engine breather system and oil separator. Blocked breather will restrict the free flow of oil from Turbocharger. This will result in seepage of oil from the Turbocharger into the air intake as well as exhaust system.  When the engine / turbocharger is not in use, close the piping openings on the turbocharger proper protective plugs  Fill the oil inlet hole of the turbocharger with clean engine oil, when the engine is started after long storage. After the oil change, prime (dead crank) the engine before starting and before starting the engine during cold ambient conditions.  Servicing turbocharger is a task for trained specialists and should only be done in authorized service centre. Check for Turbocharger Complaints: Visual and Mechanical Checks on the Vehicle  Inspect the turbocharger exterior and installation.  Listen for unusual mechanical noise and watch for vibration.  Listen for a high pitched noise. It can indicate air or gas leaks.  Listen for noise level cycling. It can indicate a restriction in the air cleaner or ducting.  Inspect for missing or loose nuts, bolts, clamps and washers.  Inspect for loose or damaged intake and exhaust manifolds and their ducting and clamps.  Inspect for damaged or restricted oil supply and drain lines.  Inspect for cracked or deteriorating turbocharger housing.  Inspect for external oil or coolant leakage; external dirt deposits (indicates air, oil, exhaust or coolant leakage).  Inspect for any heat discoloration.  Inspect for any restricted air filter.  Check the waste gate for movement and damage. Be sure that hoses are in good condition and that the connections are tight where applicable.  Check and ensure that the calibration and control of fuel injection system is in accordance with the original equipment manufacturers specifications.  Verify the part number of the turbocharger; make sure that the correct turbocharger specification is used.  Correct any installation and other related problems observed during the above check. Take corrective actions to prevent reoccurrence. Refer to the engine manufacturer's service instructions for inspection and replacement procedures.
