I have been noticing a reduction in performance with my diesel and i suspect a few causes. I think i may have a too high of pitch wheel and im sure there is some growth on the bottom. Also the diesel fuel in my tank is from last season. However, I have also noticed that I dont hear as high as a whine from my turbo as I used to. It is an '89 motor and i think it may be the original turbo. Is there anything I can do to see if the turbo is working right? I get a lot of blow-by and a lot of oil goes into the turbo. I took the air cleaner assembly off and looked at the rotor and it was very oily but it spun freely.
Basically i have a lot of problem getting outa the hole but once up to speed it cruises ok, but sometimes I even have trouble getting the motor to run up to the 3800 rpm it's supposed to top out at.
