Yes they can loose boost from just use. I have a truck that after a million miles the turbo would just not spool up only get about 20 PSI on the pressure gage. I found a couple of bad hoses. I changed them pressure checked the Air to air. No leak off there, still no more than about 20. Changed turbo and all was fine then. Never leaked oil or anything. Talked to MI Turbo about it, they told me I was one of 3 they had talked to that got a million miles on a turbo in a cat engine in a truck. When I took it in they said yup fins were worn and shot. Bearing was still good. As for the leaks causing boost problems. Read about how much a charge air cooler can leak and still be good. It amazed me they could leak that much. Mine held 30 PSI for 10 -15 minutes. Then dumped the pressure since it was good. SO I would guess your turbo is on the downward spiral. Most important thing for turbo longevity is cooling them down before shut down. Give them 5-15 minutes depending on how hard they were working just before you want to shut down. And keeping them from getting high temperatures during use. Yes you can do that. Like pulling mountains with trucks just back off after it gets to a certain point. I used 1000 degrees as my limit. yup it will go to 1200 or more also will burn the rust off the manifold too. looks like a new casting when that is done.
