depends on how much it is leaking actually...

you can buy 10 remans,.. 7 of 10 of them will weep oil if you idle a lot. It is common and knows as "turbo slobber". It is not a rubber 0-ring, but more like a piston ring type of seal in them. - It is nothing unusual, especially on a reman turbo.

Personally, just like your mechanic said,.. if you have been idling a lot, or if the truck sat for several weeks and now your running it again,.. it may just be that ... nothing to worry about at all.


-- On the other hand, if it is suddenly leaking a lot, and getting the intake side of the engine wet too,.. it could be failing, and this is a dangerous situation like others have mentioned.

if the turbo is old,.. 400k+ miles old, and ready for a rebuild, a lot of guys on here have had good luck sending their turbo to YTS in griffin,ga and getting it rebuilt for about half the price of a OE one.
