Well, I am new to Mitsubishi diesels as I just purchased a '91 Isuzu pickup that I am reasonably sure has been swapped to a Mitsubishi turbo diesel. I am thinking so, as the oil filter is the monster MD069783. Other than that, I have not spotted any engine id. numbers. Can anyone tell me where they are located? Also, there are some intercooler stuff done fairly badly. Anyone have pictures of non-modified, non-intercooled and intercooled engines for me to compare. Thaks!
