Okay let me start off by saying I have done as much research as I can stomach before even joining a forum to ask for some advice.

I have about 115,000 miles on the truck and have put 20,000 or so on it myself. I have only had one code which was for an egr temp sensor on the up pipe right off the exhaust manifold. Fixed it in an hour or two after getting the part from ford. I chased "death wobble" around for a bit and ended up just spending a weekend replacing most of the front end.

Now here is where I'm stuck. I run oil analysis on every change (5,000 miles) and keep getting 10% fuel dilution. This last change I drained 23 quarts of oil. I had ford check injectors and they told me they were fine and blamed regeneration saying it is perfectly normal. Within the last 5,000 miles or so s*** has hit the fan. I had a terrible white smoke from exhaust that smelt like fuel, checked intercooler boots which had signs of leaks. I pulled them off to see if there were any tears (there wasn't) I put them back on clamped them down and can't get them to stay on. Now I have no boost and could not figure out the best word for the sound until I found a YouTube video on "turbo howl" it's almost exactly what it sounds like except I'm not seeing the boost. Toughest part about this entire thing is that I don't have a single error code.

I'm currently right in the middle of trouble shooting. I got the MiniMaxx EGR/DPF full delete with intake elbow and flo pro 5" exhaust. Valve covers off and due to receive new hard lines and o rings for them tomorrow, Mishimoto intercooler pipes, boots and new clamps coming in tomorrow, turbo housings on both sides off with a ton of oil coking on both side (none in the down pipe)

So... should I just shut up finish my delete and go from there or do I have a HPFP leak somewhere without any error codes.

Sorry for the book. Tried to eliminate as many follow up questions as possible.

 

Forgot to add that I have already pulled egr manifold off to look at the valve and intake. Both have nasty black build up. Turbo housings also have similar nasty build up on them

 

Moved to 6.4L Power Stroke Diesel forum.

Welcome to FTE and good luck!

 

I don't know about the shut up part, but I think you might as well do the delete first. The tuner should also give you an idea of what else is going on with the other monitoring ability.

You can get into a no boost situation with a clogged dpf or damage turbo.

 

I would switch to the severe duty oil change schedule. 9qts over the fill mark means critical parts like lifters, bearings, cams, etc, are not getting the right lube.

I own a 6.4 and im not convinced that the only source of fuel in oil is the regen process.....if that were true, there would not be such a large crank case vent that goes directly into the intake....there is a lot of blow by that puts unburnt fuel in the crank case.
