TD04L. If you grab the impeller shaft with a finger & thumb & wiggle up & down there is quite a bit of play, Enough for a visible gap to appear between the blades & the inlet housing.
There does not appear to be any scoring on the inlet housing & i do understand that when oil is being pumped around the Turbo this Nodd will lesson, But it just seems a little excessive ??
This is a replacement Turbo & i did not want to go to the efforts of swapping fro swappings sake ....

There is no in & out play of the shaft (Push & Pull)

Thoughts ?

Cheers,

As you said, once the oil has circulated it normally reduces the amount of "lift" in the
shaft/bearings.


This should help to assess the condition :

Glad to help Dean - it's also wise to prime the turbo with oil prior to final fitting of the banjo bolts and starting the engine.
