I have a 2004 6.0. 153k miles
A few months ago it was bulletproofed with new oil cooler, water pump, head gaskets (machined and o-ring), seals and o-rings from the block up.
2 days ago in Woodland Park, CO, I went into the store and came back out and there was oil EVERYWHERE on the passenger side from the side of the truck to the wheel and wheel walls. I see what is wrong and the Sinister Diesel Oil Bypass filter came loose.
So I took it off, cleaned it up and noticed the threaded thing that you screw the bypass filter on was loose. So I tightened it and then put the oil bypass filter back on.
Mind you, before all this happened the truck ran perfect. Of course after I get everything back together I start driving from Woodland Park to Monument (20-25 mins) and the bastard wants to surge and hesitate at high rpms on the highway.
I get to Monument and I have about 1/4 tank of gas, I throw some Howes Diesel in the take (about 3-4 ounces of that) and I get back on the highway. Still hesitates when I WOT and it felt like it was starving for fuel. Like it would bog itself down but then be fine.
I arrive back in the national Forrest in Woodland Park, let it run to charge my camper for about an hour. Temps look good, everything looks good, FICM, ICP pressure, EOT and ECT temps, I mean everything checked out.
I go to start it in the AM, battery is dead. So I have someone jump me. It took a while to crank but finally cranked over then dies! At this point I’m about to use this puppy for my next bonfire. I’m fed up at this point.
Finally I get it to crank over and stay running for 15-20 seconds for it to start to die and the truck revs itself back up and then dies.
Today Nov. 12. 2020, now it’s at a crank and no start.
I do know the batteries aren’t as strong, here on the mountains it’s been max 45 degrees with the lows being 10-15.
I do have my typical EGR codes because it does have the delete. I have a #5 glow plug code and a small passenger side exhaust manifold leak that’s been there since I got it back from the shop.
The truck has ran like a champ even with those codes. So now I’m stuck at a no start with no codes. And I did try unplugging the ICP, still no start. I’m limited to funds and resources as I still am stuck on this mountain.
The picture below is KOEO and before I unplugged ICP.
I swear, it amazes me beyond belief that one thing could shake loose and boom, everything else decides to fail.
