Troubleshooting Turbocharger on 603.970 engine

[stephenson]

Seems like my 350 SDL is a bit slower these days ... no oil burning, great starting, etc.

Removed intake tract and desludged 6 months ago ... ugly mess - hope it is related to the early demise of the engines.

Without putting a pressure guage on, what can I do to determine if the turbocharger is working properly ... sounds like there are cars with turbos running at 100% and others at far lower efficiencies ... adjustments include the Alda, right? Check lines for oil and crud. How to check in a binary sense?

Thanks in advance!
