I don't know enough to keep from making a bad purchase (obviously), but I now know enough not to make a bad sales decision.
Had 3 bad injectors last summer when this started, and had them all rebuilt. The smoke is the same, but the overpowering diesel smell is gone. Haven't done IP timing or checked for chain elongation. I'll need help with those the first time. Power is way way down also. Takes the better part of a minute to get up to 60.
I don't ever blame anyone for seeking a good deal. If someone sacks up and asks, no problem. Just sack up yourself and say "NO".
Bill, were I to sell it to you, not that you really asked, I would require the car to be titled by name, not by vin #.
