I have a 01 v 40 that i just bought with 130,000 kms and found out the turbo was blown, so i got a new turbo installed, cleaned out the engine with a
oil cleaner and installed new oil and filter... Started the engine and it run really good no smoke and could hear turbo working...

So i took it for a drive after i warmed it up, got about 6 blocks away everything was working fine, turned around to come home when a big blue cloud of smoke came out of the exhaust and the cel came on and so i stopped the car just as the oil cap blew off the engine and it died....
Pushed it back to my shop and checked codes and it was a P0015 and also a code for the turbo being under powered...
Now the car turns over and wont start, it has had a new timing belt put on before i bought it,
Need help.. I think i bought a lemon

 

Just have to have the mechanic trouble shoot the problem. Maybe it blew ring or something.

 

Blue Smoke From Exhaust

Code P0015 "B" Camshaft Position - Timing Over-Retarded (Bank 1)
