I needed to pull the turbine housing off the chra to drill out a snapped bolt. Once I got the 2 apart there was some blackish brownish chunks (kinda like small pebbles but they looked like cubes) of junk that were stuck in between the turbine wheel and the cup and then between the chra and the cup. This turbo has been sitting on my shelf for at least 2 years and was purchased used. Would this be a sign of coked bearings? I really don't want to open up the chra unless I have to because this thing has very, very little play and it spins really nicely once I got the bigger pieces of crud out of there.

Any thoughts on my next step?

prolly just carbon build up.

 

That makes a lot of sense. I pulled apart 2 other T3's I had and 2 of the 3 had lots of crap and the turbine wheesl were black and charred. The other one's wheel was white and had very little crap in it.

Should I just blow as much of it out as possible and then bolt it back together and let the rest burn off by itself?

Thanks
