Most failures are caused by the three 'turbo killers' of oil starvation, oil contamination and foreign object damage. More than 90% of turbocharger failures are caused oil related either by oil starvation or oil contamination. Blocked or leaking pipes or lack of priming on fitting usually causes oil starvation.How do I cool my turbo?
Many turbochargers are designed without water cooling ports and are sufficiently cooled by air and the lubricating oil that flows through them.

From 1-2,400 rpm, the primary turbocharger is activated; at 2,400-2,800 rpm, the second turbocharger is activated; and beyond 2,800 rpm, both turbochargers function. This system is recommended for diesel engines with displacements of 2.0 liters and above, and V engines.Why does my turbo whistle?
