    Timing the injection pump

    Here's the very short version; pull #1 glow plug. Rotate till coming up to tdc on compression. Line up the timing marks on the harmonic balancer with the timing probe holder mark. Use a dental mirror or polished butter knife or oring pick and see or feel for the mark on the front of the cam gear...

    Build Thread 250 XLT 7.3 IDIT

    Unless you plan to go wild with the boost, high RPMs and a cam I believe the heavy valve springs are unnecessary. I'd save that money for other up grades maybe in the transmission. Otherwise you're on the right track....Good Luck.

    Dealer installed AC?

    If you can find the build sheet tucked under the seat/floor mat that would tell you. Is this truck from MN? Maybe the extra blower was to help get more heat in the cab in winter? I don't know much about the options back in '86 but if this truck is a base model maybe A/C Heat Defrost were a step...

    Who all can mod a ATS/Factory Ford turbo... cheaply?

    The concern I see with your desire is that the original rotating assembly was likely balanced as a set. If you swap even a component balanced wheel on, the assembly may still be out of balance. The shop I had balance an assembly for me a few weeks ago told me that because of the style of...

    6.9 vs 7.3 Head Gaskets and Boost

    The first turbo on that motor I'm pretty sure was an S362 but I don't know the details. In that album he's got several maps for it. At some point he went to a bigger one but I didn't see the size referenced. I believe, based on some old posts I read, his pump was in the 180cc range and he was...

    Quick Glow Plug Relay/Controller Question

    You are correct, it's not right; you should have as much voltage coming out at that point as going into the solenoid on the heavy wires. The bendy metal connection is called a Shunt. It is used by the controller to measure the current being delivered to the glowplugs. The resistance/length is...

    6.9 vs 7.3 Head Gaskets and Boost

    I don't know if this is anything but anecdotal information but I was surfing through NMB2's (the other Justin) photo bucket for his red truck and he had a nearly identical failure except on the passenger side. I don't know if he ever described the situation in a thread somewhere on the web but...

    Doing install of Wes's turbo kit

    Not you bud.....In the pics graciously shared by hanc the CDR is mounted on the valve cover backward from its normal orientation. The nipple in the middle of the CDR/tuna can is normally facing the turbo but this one is custom mounted backwards with some long bolts. Only reason I can think of...

    Doing install of Wes's turbo kit

    Just a note so there's no confusion later; good pics but for some reason the CDR valve is mounted backward on the valve cover on this engine. Maybe because someone was running a Road Draft Tube? Otherwise I can't think why it would be turned like that.

    What is this???

    Kind of looks like part of a valve stem seal that broke off and floated to the top of the valve stem?

    7.3 Head Casting Numbers

    Don't know much about casting differences but check out the coffee table book for '93/'94. That book explains all the IDI IDIT differences pretty well. https://www.forddoctorsdts.com/coffeetablebooks.html/

    Plastic fuel line connectors at the tank switch.

    @CrippledEagle Not exactly sure which parts you need but check these out. I believe there is a company that offers line adapters in brass or stainless as well as plastic. As a last resort, there is zero fuel pressure in these lines (maybe 1/2 psi in the return but others are under vacuum). As...

    5.0 to 7.3 Project

    If you have all the '92 wiring, underhood and underdash, it should pretty much lay in place in the '87 body and pretty much all the controls and functions are the same. You'll have to pull the dashes on both to swap the harnesses but the '92 harness should lay behind the '87 dash with minimal...

    Confused transmission

    Some additional details on your truck would help. Year, miles, previous rebuilds if known? Brake lights do cause problems with the transmission, do you have a third brake light above the cab with the cargo light? If so, that's one often overlooked but it was only on later trucks. Lot's of things...

    Doing install of Wes's turbo kit

    These might be a decent reference for you as well. If what you have from Wes is a Ford Factory system then there are some slight differences but just ask if you have any questions.

    Question re: fuel filter light

    It could be the the tank selector valve mounted down on the frame under the drivers door. Or it could be a problem with your rear pickup tube, or the line from the tank to the switching valve. If the "showerhead" in the rear tank has failed and a piece is blocking or stuck in the end of the...

    How does PEX hold up in diesel fuel?

    Or make them like I did, basically copying the old Transfer Flow high flow fill necks that aren't available anymore either. Rough details of how to do this are in a media folder of mine that these photos are from in case anyone else wants to go for it: Transfer Flow Style Fill Necks by...

    How does PEX hold up in diesel fuel?

    How long ago did you do this? The only larger diameter rollover valves I remember were for Cab and Chassis trucks they are much different because their fillers don't use the hose in hose design. Last time I tried to get some they were out nationwide. You can still find them at wrecking yards in...

    ICP sensor changeout......

    It's likely stored in the computer memory even if the CEL light is off. I believe the ignition cycle thing will clear it from memory. That keeps the memory buffer from filling up and keeps the service techs from chasing old resolved problems.

    Broken fpr spring

    Cold advance/high idle drop in power when switching to low idle

    In an ambulance application it's much more likely that circuit breakers were used instead of fuses for all auxiliary circuits. Reason being if a fuse blows then the staff, who is trained to focus on life support, is distracted for a much more significant amount of time than if it's a breaker...

    Cold advance/high idle drop in power when switching to low idle

    This experience is your glowplug controller timing out. It can run for a while up to ~20sec or so if it's really cold. Then it can go into a quick on-off repetitive cycle for another 10-15 sec. Your main starting batteries are hardwired in parallel so the only thing controlling flow of current...

    Turn signals come on with brake lights

    You have a tilt wheel? If so, it's likely that the turn signal switch is failing or one of the steering column bearings is going out causing pressure on the switch body making it malfunction. Poking around under there to to manually manipulate the ignition switch rod might also put tension on...
