at a reputable shop.....4-7000 dollars...with 5000 being a good fair average number (as long as major machine work isnt needed beyond honing the cylenders)
Remember that that motor still could have life in it...but its life is shortened....it could fail tomarrow...it could go anohter 100k
the turbo will probably fail within the next 50-100k max with that type of damage and isnt working to its full potential since its injested dirt and the compressor fins are damaged......
that honestly is the type of truck ive been looking for....only i want one thats gone so far as to have issues with low compression too so i can get it really cheap...
