    7.3 IDIT CDR Grommit?

    Anyone know where to find a replacement grommit for the CDR on a 1993 F350 7.3 IDIT? The IDITs have the CDR directly on the driver's side valve cover, I'm looking for the rubber grommit that pops into the valve cover and seals around the CDR inlet pipe, kind of like the PVC valve cover grommits...

    The GBT (aka my 1993 F350 CC Dually)

    I'm always doing something to my truck so I thought it would be fun to create a thread to cronicle the adventures of GBT* *GBT = "Go Big Truck"... my youngest daughter used to say that as a toddler every time we got ready to go somewhere, she never asked to ride in the car. :) The truck is...

    A/C Overpressure... or not??

    A/C gurus, looking for your help/input. Out of the blue today, while idling, twice the over pressure valve on the compressor dumped refrigerant like the system over-pressured, the 2nd time was right after pulling into my driveway and idling for maybe 30 seconds. Popped on the gauges, and...

    Worried about my 7.3 IDIT's health

    For the last 10 years or so my truck hasn't been worked too hard. Last year we bought an about 8,000 lb Travel Trailer, and the truck is once again being used as a truck. We did a fairly long vacation trip, which accounted for about 2,500 miles of 3,100 miles on my last oil change, all pulling...

    Electric Vacuum Pump?

    I converted my truck to hydro boost... which got me thinking, the only thing I need the vacuum pump for now is to operate the air conditioner controls which is very low demand. Anyone ever replace the vacuum pump with an idler pulley and use an electric vacuum pump in its place?

    Crew Cab Headliner Removal

    Any hints on how to remove the headliner in one piece on a 1993 Crew Cab (OBS)? Do I need to remove the seats to get enough room to tilt it and get it out... or in the end is it really just easier to remove the rear window and take it out the back? I have new headliner material for it, but I...

    Idle hunting...

    OK new one for me. Today I noticed that when I let off the throttle, it drops below idle RPM, then hunts around the set idle for a couple seconds before finally settling to a constant RPM. Kind of like it wants to start loping but then decides to even out. Any thoughts? I haven't made any...

    Allison 6 speed transmision?

    What ya'll think about the idea of putting an Allison 1000 or 2000 series 6 speed transmission behind an IDI? Ran across a company that makes adapter kits to put the Allison in all kinds of different vehicles, I asked them if they had one for the IDI and they told me they are working on the...

    1993 F350 Sterling Drum to Disc Brake Conversion

    Ran across a company that makes a read disc brake conversion for the old drum brake equipment dually sterling axles. Anyone heard of them... know anything about them? The conversion is a bit expensive but would be a lot less work than sourcing an F-Superduty axle to swap out...

    Glow Plug Leak

    Lately I've been getting faint smells of fuel so I stopped to check things out today. I noticed a small puddle of diesel around the #4 cylinder glow plug. Strange thing was the #4 injector seems to be completely dry. So I started it and discovered I have a leak around my glow plug by seeing...

    Injector problems?

    I recently changed my injectors. 7 of the 8 where clean as a whistle (see first picture). However the injector from cylinder #4 (remaining pictures) has definite soot/carbon on it. The strange thing is I'm not sure it leaked past the copper O-ring, the pattern of carbon looks like it came...

    Fun with numbers :) (Oil Analysis)

    I'm an engineer... so I like numbers :Thumbs Up. I have had my truck since 2004 and have put about 114,000 miles on it. With a few rare exceptions I have always had an oil analysis done at every oil change by Blackstone Labs. Since they give me all kinds of fun numbers I have tracked and...

    Vacuum Pump Oil?

    I just bought a new Delphi vacuum pump for my 7.3 IDIT. With it came a note stating 'Belt driven vacuum pumps require 10cc of 90wt hypoid gear lube. Top up as required. I've never heard of adding oil to the vacuum pump... did i miss something, should the pump be checked and topped off every...

    Drone nose?

    I'm getting a somewhat loud 'droning' noise that can be heard throughout the rpm range but most noticable at idle. Kind of sounds like an open intake plenum, like the airfilter was missing but louder. I also seem to feel a vibration and maybe a cylinder miss at slightly elevated RPMs in...

    Quick flywheel questions...

    My DMF is pretty much done. so I'm installing a new Valeo SMF. My old DMF flywheel had this ring spacer to distribute the loads of the bolts but I did not get one with the new flywheel. Does the new SMF flywheel not need one or should I use the ring off my old DMF? Also my new flywheel bolts...

    Tire shop: rant/question...

    Getting new tires on my truck always ends up with me getting pissed off. Every shop I've ever tried just doesn't give a crap. If it's not my alloy dually rims being drug across the damn tire changer putting gouges in the wheels (which they always deny claiming it was already there, even when...
