my 92' w 275k is in the same boat.....anything below 1000 rpm and you can hear it. Above 1000 you cant hear or feel it. Im curious as to the origin, whether its a rod bearing or piston slap. I tried using some rotella 15w-40 hoping it might help the noise but it didnt. Might try to get a video the noise......Im planning on getting a new shortblock anyway next time SUbaruparts has 15% off, but id like to keep going on the original as much as i can, be great to get 300k on it (just for braggin rights)................
