I'll be checking the bearings for play in the spring, but my car has the original turbo after 184k and it still works just fine. No noises, unusual oil consumption,or other common signs of impending failure.
It'll be fine. The oil cooled (only) turbo in my '86 Volvo 740 Turbo lasted a long time. Still going strong after 285,000 Km and 18 years. I then sold it to friends who drove it for 5 more years and the turbo was still fine.
Oil was not as good as today's (always conventional, often Pennzoil PZL Turbo) but changed every 3 months. And letting the turbo cool after hard driving.
