PLEASE READ BEFORE CONSIDERING DIY INSTALLATION OF THIS TURBO CHARGER CARTRIDGE,PROFESSIONAL INSTALL HIGHLY RECOMMENDED

The number one cause of most turbocharger cartridge failures can be traced back to the engines lubrication system.  The cartridge bearings depend on a constant flow of the correct grade of  good clean oil to function properly.  Several factors can lead to the break down of the turbo lubrication system including lack of maintenance, incorrect grade of oil oil or filter, severe driving conditions, or in most cases simply the age of the vehicle can contribute to degradation of the turbos supply of oil.

The bearings in 90% of all production cartridges are a full floating bronze bush bearings which support  the turbochargers main rotating group.  The clearances between the bearings and housing are very tight so any contaminants/dirt/grit etc held within the oil can do damage very quickly if not corrected.  The best defense you have against oil borne contaminates is a very strict maintenance schedule.  

Often the OE manufacturers recommended interval between oil changes will not be sufficient. Turbo manufacturers recommend changing your oil and filter any time the oil starts to change from its original golden brown to a darker brown color.  In some higher mileage cars this could happen within 2000 miles or even sooner.  The reason the oil is changing color is due to a few key reasons.  First, most of today’s oils are very high in detergent, this is designed to keep engines cleaner longer.  Unfortunate for the turbocharger  these detergents deposit a large amount of engine “dirt” into the lubrication system.  If left unchanged for 3500 or more miles the oil becomes saturated with this accumulated dirt and starts to become very abrasive to the fine clearances inside of the turbocharger.  

REMEMBER keeping your oil topped up with the correct grade and regular oil and filter changes are critical to the life of the turbo charger....when installing your new turbo an oil system flush out and replenishment with new oil and filter is extremely important to ensure no contamination is caused to the new turbo...Seek professional garage services to install if in doubt.
