Truck, 2002 F350 CC SB 7.3L 68K miles, 3.5" to 6" aussies, intake, customs tunes(High power EF, Torque Tow, Tow Power). I was using the Tow Power tune.Trip was from Virginia to Dallas, TX i was hauling around 8.5K in my 24FT enclosed car trailer. total trip 1450 miles. every 2 hours i would pull over to check tires on trailer and truck, fluids and so forth. 600 miles in and about an hour since the last check i pulled off the highway and when i got to a stop... KNOCK KNOCK KNOCK... sounded like a bottom end bearing. I had to make it to Texas so i pulled into the walmart and changed my oil(which was about .5 qts low) and substituted 1Gal. of diesel oil for LUCAS oil additive. knock was still there and didnt get any quieter, made the execuative decision to drive it till it quit... well it never QUIT! Made it over 900 miles! it was blowing oil out of the oil pan gasket, it seems to have pressure in the oil pan, so i am sure i have melted/cracked a/a few pistons. but damned am i proud of that truck! Had i not been starting my new job on monday i would have not pushed it, but i trully had no other options. now what would you suggest i do? I have about 3,500 dollars in the trucks savings... any suggestions on which internals to buy, or go with a short block. I plan on getting some forged(factory forged rods form diesel innovations) and some Mahle pistons, new bearings and calling it a day. input please...
