Hey everyone. I am grateful for all intel on this little gem I found. I have a 1985 dodge ram diesel with the 4d55 motor. I am looking to learn from a manual but I cannot seem to find a repair manual that contains diesel information. Keep in mind I have only been a member here for 5 minutes, so it might be listed and I havent found it. Any help will be rewarded with great karma. check out my truck under my account photo albumn. I just uploaded pics.
