i was under the impression the core is worth about as much as a new turbo, and its not economical to repair them.

i just taken it off. there was one nut missing so it was blowing. maybe that could be the noise?

the play in the shaft is .5mm. the blades look mint. i was expecting the oil feed to be leaking, but its not. i'm not too sure how one of the water feed pipes is caked in oil.

also, there is a tiny bit of oil residue in the IC pipes. the car isn't bruning oil though. is that normal?
