Stupid question but I better ask it

[usetaboost]

I know it's normal to have a slight up and down in shaft play. Is it normal to push up on the shaft and spin it at the (on the inlet/MAF side)
same time and hear a slight metal on metal ? I wouldn't think that's a good thing but who know's, that's why were all here, right ? Haven't seen any oil anywhere yet and from what I read it's more common for seals to go out before bearings???

Metal on metal is never good. Looks like it's time for a rebuild - or - a nice new one from Full Throttle.

Only get it if I push as hard as I can and turn. Just starting to go or the beginning of a bad ending?

It is possible that you could be hearing the shaft rubbing on the bearing, but I highly doubt it due to the film of oil on the bearings and shaft. What you are probably hearing is the compressor wheel rubbing on the compressor cover, or turbine wheel rubbing on the turbine housing. If you can pull the shaft far enough to the side that the wheel touches the housing or rubs on the housing when spun, the bearings are starting to go bad. I would recommend you have it at least looked at by a reputable turbo repair facility as a bare minimum. If the wheel is rubbing on the compressor cover, it's only a matter of time before the tiny pieces of aluminum turn into big chunks of compressor blade and compressor cover. These big chunks could possibly cause damage to your intercooler if lets say a piece of the blade breaks off under WOT and goes flying ballistically into your intercooler. Not too metion if it made it out of the intercooler and into your engine. No questions are stupid questions. We all have to learn how to walk before we can run.
Just my O2's worth.

Well after I get the tranny done I'll cruise it down to the local diesel shop and see what they say. No oil yet, looks dry. Fired it up and let it run for a few seconds and wheel looked like it spun nice and steady. Maybe it's just starting , with 113k on it, maybe I'll just replace it at the end of the summer or sometime next winter. Car probably won't be driven too much anyways. Thanks.
