There's a shade-tree mechanic trick that you can use for noise diagnoses. Cut a garden hose and use it as a stethoscope to try to ID where the noise is coming from.
But, I agree with Dave 100% on his suggestions:
If you're having turbo problems, a rebuild is an easy win. I'm sure there's a rebuilder local in PDX. I used one in Tacoma. They took a turbo that looked like it had been sitting on the bottom of the English Channel for years and made it look and work like new.
The head won't be hard to pull and any engine shop will be able to inspect it and make recommendations. It's not a super-expensive job to get a head planed or otherwise rebuilt.
good ideas.
Ben, go to Ship's and ask him if he'll let you borrow a used, take-off turbo. You could install it and see if you notice a difference in the two turbos. I'm sure Ship has several sitting around.
