Message: [QUOTE="elrodalexander73, post: 1319453, member: 16217"] Ok... lets break this down, you bought a higher mileage 7.3, added some tunes, had EGT issues, and then you popped a radiator, this is what I would have done first, and I know it's useless now BUT it would have been wise to replace the known failed radiator first, get the truck to hold coolant, then do a pressure test.. Fill with coolant, let it sit over night, if you don't loose any by morning you can rule out any thing going into the engine, if you pull the pan plug in the morning and coolant run's every where you've got a problem. 2nd you shoulda drained the oil and had an oil analysis done, and if it was confirmed fuel from say a cracked injector tip, these injectors prolly have 330,000 on them, it does happen, I've rebuilt two 7.3s and had to have one sleeved cause of this failure, then you know where to go. BUT if you have excellent cross hatch in the cylinders, no evidence of trashed fire rings, buy some ARPS now, get a set of 910s, replace your cups, maybe even have a basic valve job done, have your injectors tested and put it back together.. You can always pull the oil cooler down and look inside it and see if the rubber is really rotten.. If it looks super bad replace it, hope this helps. [/QUOTE]
