Attention: TDR Forum Junkies 
Well, left for vacation 1 week ago, and everything went wrong.
My truck in current configuration has consistantly got 15 - 16 mpg average. Two weeks ago, I took a trip to Toledo, and mileage was down to 14, but I attributed it to towing the jet skis.
Leaving for vacation last week to Pensacola, FL, netted me 12 mpg on the way down. I noticed some white smoke when starting cold, but would clear up after 30 seconds or so. When we got down to FL, I noticed that engine RPM would "hang"... when punching the throttle quick, the engine used to be very responsive, revving quickly and come back down quickly. Now, when patting the throttle quickly, the rpm hangs at 1100 - 1300, and sometimes will not fall below that even after 2 minutes or more. Also, on the way down, I noticed the truck "hazing" constantly while driving... much more so than was normal. A passing truck even slowed to flag me down, because the hazing was so bad. The passenger side jet ski had a thick black film on it when we got to FL. I checked oil level at each fill up, fearing an injector had hung open, but all was normal.
Would it be possible for an injector(s) to be slobbering, or dribbling fuel that would cause the rpm to hang, poor fuel economy, white smoke at start up and constant hazing?
Second big problem... the day we planned to come back, shifting got VERY hard... almost to the point it was impossible to get it in gear. I've daily driven the 3850 DD clutch for over a year now, and usually don't have any trouble; however, no matter what you do, it's almost impossible to get the truck into gear, and very hard to shift once started. The shifting would be compared to not having a clutch at all, and having to synch the gears almost perfectly to avoid major grinding.
My first thought was hydraulics/slave cylinder. However, I believe the clutch is disengaging properly, because I adjusted the rod out to the point that pressing the clutch too far gives the "tat-tat-tat-tat-tat" sound. But, it seems like when the clutch pedal is pressed all the way, that the clutch is still trying to grab... like when you start the truck in gear, the truck tries to take off even when the clutch pedal is pressed in to the point of hearing the "tat-tat-tat". Any thoughts?
I've been running Smarty TNT#9, TM 3, RP 2, Timing 4, TST standard program on 2/0 or 3/0, and TS MP-8 on about 10%. RP cruising is around 17,000 psi. I installed the 3850 sprung hub DD SB clutch about a year ago with upgraded hydraulics, and, while it's always been tricky to shift, it's been fine.
I've recently been working through the installation of a Mitchell gear splitter, which is just a 2-speed overdrive unit that mounts in a divorced configuration... but I've been driving with the unit installed for several weeks without problem.
Just before I left, I also got a BAD oil report from Blackstone, showing the oil was saturated with soot, copper of 213, iron of 122, lead of 21, chromium of 6, etc, etc. This sample was taken at 8,000 miles running Schaeffer's 9000 5w-40 synthetic, Donaldson ELF7349 high efficiency oil filter, OilGuard bypass filter, FilterMags on the outside of the primary, and some very strong neodymium-iron-borite magnets inside the OilGuard housing as well.
I've always ran GDP's 2 micron fuel filter, a 7 micron in the OEM canister, FilterMags on the outsided of the 2-micron, and used Schaeffer's diesel treat with every fill up.
Well, to top off the vacation, I jack-knifed the jet ski trailer and caved in the passenger side of the truck, and got a good case of food poisoning/diarrhea as we were leaving to come home. And, when under the truck looking things over, I noticed 2 of the Sway-a-way shocks were busted and leaking oil badly
Any suggestions on anything? (well, besides the diarrhea... it's passed now :-laf)
Signature is current, with the exception that the Helix 2 and springs are still waiting to be installed... .
Thanks..... Eric
