Turbochargers spin out over 240,000 rpm and operate in temperatures of 950°, and the bearing surfaces depend upon a film of high-quality oil to keep them apart during operation. If you take this oil away, the effects are disastrous, and can literally happen in the blink of an eye. It is essential to ensure that the engine oil pressure, Mesa manufacturers specifications, and that the correct oil is used, and we would recommend a very high grade of fully synthetic engine oil.

We find that the vast majority of turbochargers that we replace have some form of oil starvation.

So what causes oil starvation?

• Low engine oil level in the sump
• A bent or kinked oil feed pipe
• Carbon deposits, causing a blockage in the oil feed pipe
• Blockages caused by using silicone when fitting the oil inlet gasket
• Incorrect oil gasket restricting oil supply
• A blocked, damaged or poor quality oil filter
• They warn oil pump
• Not priming the replacement Turbo with oil during fitting and start-up
• The engine, not being used for long periods, particularly in cold weather

To prevent oil starvation to your turbocharger

• Do not use silicone on oil gaskets. It can easily become detached and block oil passages
• Clean or replace oil inlet pipes to eliminate any carbon deposits or sludge that could restrict oil flow to the bearings
• It is important to check the oil pressure and oil supply to the Turbo
• Always use high-quality fresh oil and new oil filters, as recommended by the manufacturer, when fitting a new turbocharger.
