Ok,I gave it a 2 hr check over,Checked coolant and oil, Engine was dead cold,glow plug light took about 8 sec to go off,didn't start on first burst but I only held key for about 3 sec. 2nd crank over fired right off and only thinly puffed grayish black smoke for an instant,let it idle for 15 minutes almost smooth as my Gasser,no smoke,shut it off,rechecked fluid,no change,restarted after 5 or so minutes,fired right off with even less smoke puff.Ezed down the road,tranny shifted smooth,no ruff engagement,no grind,no slip or lug.Then I commenced to drive the s... out of it,Little black smoke at top end of 3rd,4th hammering on it,run it up to about 80mph in OD for a bit,stopped,shut it off for a couple min.,started right up and off we went.Fluids looked good at end of drive,no body rattles or squeaks,no visible rust or damage,rear fender flares intact w/no cracks,one fuel return looked damp,engine temp never got to half on gauge,I'd say about a 1/3 way up,tach must have a short in it.steering had slight mush to it but not bad,electric window worked as all other interior stuff did,two knicks in the dash over the radio,seats and carpet with no rips but a couple small cig burns....So what yall think? 1994 F-350,7.3L,202000 miles,chrome rims and lugs,chrome big bell exhaust tips,no body damage,tires on rear fair,front new,16" tires, $2,300
