D24 - noise on acceleration

volvobm · May 5th, 2011, 12:14

When I accelerate hard I get a high pitch sound. This morning I even had a small loss of power and the off it went. I have an 87 d24t with 204000 k.
Any remarks welcome.

in the green book it says check axial play . that turbine does not scrape housing when pulled axially
check radial play that compressor wheel does not scrape housing when pushed sideways and rotated. hope this is some help
