Thanks for the input folks.... I did a little more investigating this morning, and I think I was barking up the wrong tree....
I removed the boot at the bottom of the intercooler with a dish pan underneath, expectig a bunch or oil/ water gunk to spill out.....
Virtually nothing, a very little amount of moisture, but no buildup on the inside of the pipes or sludge. SO, I then fully disconnected the pipe between the top of the intercooler, and what appears to be the throttle body?? I can see the butterfly valve inside. Anyhow, it was very clean as well. The valve was shiny, and although there was a bit of moisture in the pipe, the only sludge seemed to be minimal and built up around the hard edges leaving the intercooler and into the rubber boot.
So, I'm now thinking that I don't have much oil leaking into the air system. This is a good thing I guess
However, it doesn't explain my sluggishness when I hit the accelerator in a hurry.
If i'm leaving a light with traffic theres no problem, gradual acceleration is smooth and strong for the most part.
My problem is when i'm pulling out from a stop into traffic and I need to GO...... It really take a second or so before anything happens with regard to power or movement when I mash the accelerator.
it's tough to really document this, but when i hit the pedal, the motor does begin to rev, but I don't think I really start moving until I get to 2K plus RPMs..... Maybe this is normal, someone said in another post that the stock torque converter didn't start to lock up until 2K RPM? Maybe this makes sense, but i'm still a little confused.
Sorry, i'm still pretty new to all of this. I've had other 3/4 ton and larger trucks, but they were all gassers.... They never exhibited this lag that i'm perceiving.
I honestly can't tell if the lag is because of the Diesel needing a little time to spool up and apply power, or whether something isn't working correctly.
I don't remember this issue when the vehicle was new, but it has been this way for over a year. I'm also tending not to buy into the diesel lag issue, because ford marketed the 6.4 with dual turbos, so that there was minimal to zero lag time......
I suppose I could stop by the dealer and ask to drive a new one off the lot to see if it handles the same, but if anyone here can comment as to what I should be expecting that woudl be great. I know a lot of folks who have gotten rid of the DPF and added some computer programming don't experience this, so I guess i'm interested in what I should be expecting with stock.
