Okay so i bought a 2003 f350 270k miles on it from a guy who used it for his roofing company and got it real cheap since they stated there was a problem with the truck but weren't sure what it was. The guy driving the truck said he saw white smoke, pulled over and saw coolant dripping from one of the core plug holes on the engine, drivers side. He said it didn't over heat on him and that after he noticed the water leaking, he shut the truck off, had it towed and has been sitting ever since.
It was missing the plug on the block. I found it was missing one on the passenger side too and a few of the heads core plugs were starting to pop out a bit. I found the thermostat was destroyed into pieces too?? After fixing all that i found water in the oil! I thought egr and oil coolers were bad so I removed them and had them tested and to my surprise, they were original and they BOTH were still good!! The hose in between the coolers was busted though. I drained the oil and a few gallons of water came out then oil. I left the oil drain plug out, poured water in hole on top of the front cover where the intake goes and as I expected, water started pouring through the oil pan hole! Could this mean the front cover is bad? maybe cause of cavitation? I've seen a 6.0 without a front cover but I don't know that it's possible for oil and water to meet there? is this possible? has anyone seen this problem before? does this relate to the plugs and the blown up thermostat?
I'm thinking the core plugs on the block are actually part of the crank case, water filled up the crank case high enough for a pistons to catch some during BDC and high enough to start leaking out of the core plug hole. thanks in advance
