How much side to side play are we talking. A turbo that has got worn oil seals won't necessarily have play int he shaft (mainly dependant on how abused its been)

The oil return is a very good suggestion, if they are blocked then it will force oil past the seals, turbo's work on the law physics so everything needs to be right.

However, those oil return pipes go very hard and brittle, so be carefull what you do.

P.S i cant say ive ever seen another thread by you, especially in the last 3 days lol
