Turbocharger Replacement: How to Replace It

Hello,

I want to replace the turbocharger on a 1.5L dCi (Renault) engine. (The shaft has some play, it's producing white/blue smoke, and there are grinding noises from 2300 RPM.)

The cause, in my opinion, is a lack of maintenance (e.g., the air filter and very old oil).

What else should I replace? I'll take a look at the oil lines and try to verschandeln them.

Replace charge air hoses/coolers when replacing wood chips?
Should I perform an oil flush using cheap oil?

Best regards,

You should definitely replace the oil line if there's even the slightest doubt that all dirt particles have been removed. If it's a hose, it should generally be replaced.

Because intercoolers should also be checked for debris if there's a possibility of shavings being present.
