Stock turbo shaft play associated w/smoke (video)

1fastt2 · 09-18-2016, 10:44 AM

Hey guys I posted this video in another thread however I feel it may be better in it's own post. I've been chasing an oil burning smell and smoke mostly at idle and on decel. I've performed all the pre turbo removal culprits that may cause smoke. IE: PCV and valve cover gasket which yielded no difference. The car now has an RB external PCV system with catch can (plugged head) and a new valve cover gasket.

I feel the shaft play is excessive, what are your thoughts?

Here are pics.

Dude if these things are spinning at 100,000+ rpm, almost any play is too much.

Axial play is bad enough but radial play. yeah those are bad. either get them rebuilt or get new oem turbos.
