Hi my 04 subaru smokes when hot and leave idling for a couple of minutes blue smoke comes out of exhaust was told the turbo seals go I think my turbo is a td04 13t can I fit a cassette in it or best to get rebuilt or will a replacement turbo from ebay be ok ?

 

Check your PCV valve mate.

 

I did change the pcv valve a few months back but thanks for the advice
