so it could be doing this because my exhaust isnt on then?i thought it would be ok to run it with now exhaust on it for a minute or so?
My understanding it that the bearing seal simply wont work without back pressure.
You've got to fit the exhaust on at some stage, so why not fit in on now and see if after a few mins of running there is oil/oily smoke coming out of the tail pipe?
