I'm going to change the oil and put a clear line on the return line see what i can see. glow plugs are next week. trucks been sitting for a few years without running and the oil was changed but it sat for 2 years with fresh oil in it... if I have a lifter collapsed im going to throw some engine flush in before i do the change and add some lucas stabilizer to the new oil. I usually use delo 400 15-40. this thing has no leaks so I may look for a synthetic oil instead.. any advise as to which oils to stay away from? also i have seen diesel oils that are 5-40 synthetic... are these safe in the older diesels?
