N63 Turbo oil line and return line replacement DIY Video

7min time-lapse of E70 XDrive50i Turbo oil line replacement
& Oil return cover replacement.

Known issue in many the N63 V8 engines. Google finds stories...

Temperature under turbos get so high that return cover gasket fails under heat shields, and oil "boils" inside turbo lubrication lines clogging them.

Peak temps happen if battery gets old or low voltage and does not allow Aux Turbo coolant pump run 10mins after engine shutoff. Another scenario is when turbo coolant gets low due to the leak, or coolant pump dies completely.

Symptoms: Oil leaking under the car in bell-housing area between engine and transmission. There is a drain hole above the rear main seal, letting leaked oil drip down from V-valley.



Nothing pairs better with German car repair than Modern Talking eurodance remix
Well okay, you can mute the music!
