Turbo passing oil D4D


Recommended Posts

I have a 2002 Rav 4 d4d.

Recently replaced turbo core, last one hade a major fail. All went back together ok but I now have Oil passing the turbo seals, definitely on the air side and I think also on the exhaust side.

Did all the usual clean up and oil/filter changes, cleaned out the sump pan and blew out the turbo return line.

Getting a fairly rapid increase in breather pressure from the top end so I am wondering if its ring blow-by or leaking injector seals. Had a look at injectors with TIS and see two are slightly positive and two negative on displacement at idle, is this a clue?

 

All comments welcome...help!!
