Turbo health checks

[aidan8888]

This is something new to me so you will have to bear with me.

Ive dismantled a fair bit of my cars engine bay to swap the exhaust manifold, and while it is all off I thought I would check over my turbo. Can anyone tell me what to check and how? Also, some of the intercooler pipes had oil around the silicone joins (on the inside), is this something to worry about, is it a good idea to flush out the intercooler?



Cheers

(for reference it is a Nissan turbo rebuilt with steel internals).

Sorry for delayed response, I did as instructed, no forwards/ backwards play. A little bit of sideways play but only 1-2mm and it doesn't touch the housing.

Thanks for the advice, im happy to put it back on now

Nothing fancy like ball bearings, its a standard Nissan (garett?) turbo with steel internals. However, when I flushed the inter cooler I did get a fair bit of oil in it, so a bit more concerned about the turbo now.
