When I blew my 60trim it had absolutely no up/down shaft play, but had about an eighth of an inch in/out play .lol I had oil practically spraying out of my exhaust, but had no oil on or around the hot side or o2housing. It was all still still sealed in the exhaust. Only thing I could say is unbolt the o2housing and serperate it just enough to look on the inside of it and the turbine housing for oil. You would know it if it was blown tho.... White wall of smoke behind you and/or the sound of marbles in a blender... Lol
