The good news is that there is a big chance that the turbo is fine.
1. Check all the ducting for loose or broken clamps, hoses, vacuum lines, and seals. |
This is usually very bad because it's either the turbo that's gone or the engine. White smoke comes from burning oil.
1. Open the intake so that you can see the inlet turbine of the turbo and see if there is an excess oil gunk all over, that would point towards the turbo bearings leaking. |
Sounds like bad news...
1. Open the intake so that you can see the inlet turbine of the turbo and see if there is any damage to the turbine itself. If so, replacement of the turbo is needed.
If not, see if the shaft has any play, check the specs of the turbo for how much play in and out it can have and make sure it is within the specs. If not, replacement is needed especially if the turbine is wobbling because the bearings or the shaft are shot. |
| 2. Check the PVC valve. |
2. If you pass #1 and the turbo is clean, I'm afraid you'll have to take the turbo off and look inside the exhaust header to see where the oil originated from. If you're lucky, the header will be clean and you'll only have to replace or rebuild the turbo. If there is oil residue in the headers, most likely your valve guides are leaking oil, and you will need a head job, but hey, maybe the turbo is OK. |
2. if you pass #1 and it's still making a noise, check for something loose like screws or bolts. |
