So here's the scoop, and this will probably be long...as I want to try to be as informative as I can so you guys can try to help me as best as you guys can. PLEASE bear with all the information, skim through it if you'd like for the good parts. I'll underline the parts that I feel are important.. I really need some help here
My uncle's truck is a 2005 6.0 4x4. It has about 120k on it. as far as I could tell from today, these are all the mods:
-It's lifted 6 inches and turning 37x13.5-20s.
-It has a tuner on it(although I'm not exactly sure what kind)
-Has a K&N intake system, and it appears the intake neck and everything else has been replaced as well...as it all looks very different than my own 6.0 does. It looks like it's all chrome.
-has an exhaust system
-egr delete[?](as we learned from our adventures today, i think...although im not sure what i'm looking if it's just a blockoff or what.)
-some sort of fuel pressure regulator(when he cycles the key..the pressure gauge will climb up to about 55 PSI)
-aftermarket gauges for EGT, EOT, ECT
A few days ago he filled up with diesel from a place that is not the usual place.
Today, he went from home to another part of the metroplex, only about a 20 mile drive. On the way, he stopped at a store, and when he came back out...he started the truck up and it was a very rough start. Said it sounded like a lot of knocking/metal on metal for a few seconds, then smoothed out a little. At that point, it started bellowing out white smoke.
All the way home, til he parked it, it continued to bellow out white smoke in very large amounts. He stopped along the way, shut the truck down, and started it back up to no avail. From what he recalls, his gauges never moved a bit. the truck lost a ton of power, but the fuel mileage didn't seem to change a bit when he reset it(still about 15.5)
When I got around to the truck to look at it.... We checked out everything that we could. drained the fuel filters, and very little water came out. We went ahead and replaced the fuel filters, as the filters looked like they might have had some sort of rusty residue in them.
We checked the FICM. It was reading a full 48 volts all the way across until we tried to crank the motor over, which was then when we learned that the motor was compression locked. We cranked up the rear of the truck and went to pull the egr valve and learned that there was a blockoff plate in its place. So...no egr valve. Pulled the plate and let it sit but never saw any coolant inside the port. I'm not sure if the EGR cooler has been upgraded or just the valve got blocked off. I'm not sure how to tell.
The coolant was perfectly clean, and smelled just like it should. The oil looked great, and was at its proper level. not over or under.
I proceeded to remove the glow plugs in order to try to spin the motor over and clear the fluid in the cylinders, and after getting only the driver's side ones out, I stopped...as each consecutive one had been covered in oil as I pulled them out, coated up to about an inch from the tip. the cylinders appear to be full of OIL
I have stopped at that point for the night, BUT I really can't figure out what is causing this. Our original first thought was "water in the fuel" given the original circumstances. My first thought now is possibly a turbo seal. All of the intake tubing that I looked at had a thin film of oil inside of it...but It wasn't enough for me to think that the seal had blown badly enough to FILL the cylinders with oil. The bottom of the inside of the turbo housing cold-side had a little bit of oil in it..but not much.
ANY help is very very very much appreciated, as this truck is stranded in the driveway and my uncle's pocket book is not in good enough shape right now to just take it to a mechanic and let them try to figure it out.
