DD15 blown APT

[Nilao]

If your dd15 is like the one I used to have the turbo should be fine as the APT is downstream from the turbo. The turbos on the dd15 is a fixed valve model so no nozzle ring to worry with getting gummed up. I would just have him clean it and reinstall.

Now as far as the oil getting into the one box..I hate to be the bearer of bad news but one oil penetrated the filters they are toast. They usually crack once the oil hits them due to thermal shock. So those will likely need to be replaced and are usually worthless for core charges.
