    How to wake up a 7.3 from a 10 year slumber

    If oil gets squirted into the glow plug hole, wouldn't that hit the pre chamber instead of the piston top?

    runnig.tail light trailer wont work rest work fine (brakelight,right,left light)

    I believe the cover for the fuse box should say what is what in the box. The daytime running lights are what activates the relay, which sends power to the tail lights on the trailer; so plugging that back in MAY solve your problem.

    runnig.tail light trailer wont work rest work fine (brakelight,right,left light)

    Unfortunately, I'm unsure which one is which in the box, I haven't been inside of a 1992+ engine compartment fuse box. I have only been going off the wiring diagrams..... The middle relay is the horn relay, the trailer marker light relay and the fuel pump relay are on either side of the horn...

    runnig.tail light trailer wont work rest work fine (brakelight,right,left light)

    If the fuse is good, you get 12 volts to the relay socket, but no 12 volts to the trailer plug when the running lights for the truck are on, I would be tempted to just replace the relay. I think they are pretty cheap.

    Your 1994 doesn't use fusable links like earlier trucks. Fuse D in the fuse box in the engine compartment is for your marker lights. The relay for the marker lights is also in that box, that could be bad too.

    runnig.tail light trailer wont work rest work fine (brakelight,right,left light)

    What truck do you have? Do you get 12 volts to your trailer plug (assuming your dealing with 6 or 7 pin wiring) I just went through the same thing. Ended up being a fusable link next to the passenger side battery (on a 90 or 91 truck, may be different on other years)

    IDI Front wheel drive trike

    You're not thinking big enough. https://youtu.be/A1fvcp--Lzk http://www.ridingvintage.com/2013/06/motorcycle-chariot-racing.html?m=1 Now imagine using your idi trike instead of a motorcycle.

    dynamic timing: ford vs navistar?

    That's what I did. I used a ferret pick up and an adjustable timing light. My engine is set to 9* btdc right now. I was just curious about Navistar calling out 3.5* btdc.

    dynamic timing: ford vs navistar?

    no torque output listed in my specs. This does though: http://www.arb.ca.gov/msprog/onroad/cert/mdehdehdv/1990/navistar_lhdd_a0040129_7d3_6d0-0d6.pdf The A130, A155 and A170 are listed in my book. 332 ft/lbs @ 1600rpm for the A170 ford lists as having 345 ft/lbs @ 1400rpm. That does...

    dynamic timing: ford vs navistar?

    specs say 170hp @ 3000 rpm for navistar vs 180hp @ 3300 rpm for ford in 1988. Doesnt sound THAT detuned. Maybe if the navistar were allowed to rev to 3300 rpm it might make 180hp too?

    dynamic timing: ford vs navistar?

    That's what I thought at first too. But the Navistar manual does specify 3.5* btdc via pulse method at 2000rpm. The procedure in the Navistar book is exactly the same as the ford procedure. Just different spec.

    dynamic timing: ford vs navistar?

    I was looking through the engine manual I have for the navistar 7.3 idi, and I noticed that navistar specifies that the engine be dynamically times to 3.5*+/- 2* before top dead center at 2000rpm. Ford specifies 8.5* +/-2* at 2000 rpm. Both navistar and ford specify a kent-moore tach-n-time...

    extra cooling?

    If recall correctly, the aftermarket thermostat wont open all the way because of the design of the engine block where it mounts, but the OEM one will open all the way. The IH service manual details this. I will try and remember to scan and post it in the morning.

    Low oil pressure after overhaul?

    I'm not terribly worried about the pressure now, would be nice to have it 10psi or so higher at cruising speed, but I'm not gonna fuss with it unless that McMaster Carr spring gives out or something. After I have a few thousand miles on the engine I will be switching to amsoil 15w-40. The hot...

    Low oil pressure after overhaul?

    Update: I put my VDO pressure sensor in the factory switch location and the factory switch on top of the turbo where the VDO sensor was. I now get 40psi cold idle, 60psi cold over 2500rpm, 15 psi hot idle, 40psi by 2000rpm hot and 40psi at governor hot. I guess it was the sensor location all...

    Low oil pressure after overhaul?

    The mcmaster carr spring got installed yesterday, along with the regulator valve from my broken header and another bundle that I cleaned (just in case the one on the engine was plugged...). Made no difference. 20 psi cold idle, 30 psi cold at 2000 rpm or over. 10 psi hot idle, 20-25 psi hot at...

    Low oil pressure after overhaul?

    I didn't take the tube off. The pump/tube came off and went back on as one assembly.

    Low oil pressure after overhaul?

    I took apart the spare broken header I had to measure the spring: 1.472" free length .470" compressed length 0.414" outside diameter 0.041" wire diameter And a crude, unscientific test using digital calipers and a kitchen scale gave and approximate rate of 10lbs./in Plugging the...

    Low oil pressure after overhaul?

    Maybe. I can take my spare idi regulator apart and take pictures with measurements. It's used though. The 6.0 one looks like the spring it's a smaller diameter....

    Frozen transfer case shifter

    I doesn't slide, it pivots, which looks like sliding when in the cab. Look at where the handle attaches under the truck, that arm it attaches has a pivot point closer to the transmission. Picture may be better:

    Low oil pressure after overhaul?

    If I could find a new header I might be tempted to take it apart to measure the spring length and compression rate so new ones could be sourced.....
