    Source for new 7.3 IDI engine?

    You should be able to get some rebuilt heads cheaper than that, but don't go too cheap. I got some with a 6 month warranty and a month 7 they dropped two valves. Two or 3 years ago I checked International here in Dallas. They still had the 7.3 turbos for about $8000

    Glow Plug Idea Question

    You should be able to put a resistor in series with the glow plugs to lower the amperage. But i haven't got a clue as to how to pick the right sized resistor. I use a manual button for my glow plugs. On cold days I'll press for 8 seconds. Lift off and give the engine 5~10 seconds to suck the...

    86 6.9l water pump

    Hopefully your fan nut comes off easy. If not, check this thread. https://www.oilburners.net/threads/fan-clutch-nut-size.88480/ It shows a simple tool that I had to make the last time I changed a pump

    Electric fuel pump pressure question

    I've run an electric fuel pump by carrier for years, but it finally died. I wasn't able to get a replacement through carrier but found a Chinese knock off. It doesn't hold a candle to the carrier pump and now it's sprung a leak. After checking some forums, I've picked up a Holley 97 GPH RED®...

    Top speed 55mph normal for 6.9?

    Side note, l've also had a 6.9 with the same water separator. It started leaking the 1st time i drained it. Instead of bypassing it, I tapped the drain hole and screwed in a radiator drain cock.

    Top speed 55mph normal for 6.9?

    I've got an old Uhaul with a 7.3. It had gotten slower and then the electric fuel pump died. Replaced the pump and still couldn't gain speed until I replaced the fuel filter. The clogged filter is probably what killed the pump. Anyway, I'd start by replacing your filter.

    Time for a new GP harness

    Thanks snicklas. My biggest worry was that by connecting the wts light the the same terminal as the new button in the cab, you'd be making a 2nd path to ground and have constant power to the glow plugs. So I got under the hood with a voltage tester and some jumper wire to figure things out. I...

    Time for a new GP harness

    Finally an update and questions. I got one of Wes's kits for a turbo and moved the GPC. Good thing too, 2 of the wires were pressed tight to the oil fitting for the turbo and had grounded. I also had to make my own bracket for the GPC. I decided to do a GPC bypass and followed the directions...

    Coolant Flush Procedure

    I've never bothered removing one. I use those kits where you tap into the heater hose. It can take a while if you have a lot of rust. But seems worth it to me. I do a final drain after the tap water flush, radiator, lower hose and engine drain plug. Button her up, add coolant and top off with...

    Can I replace my CDR valve with an oil catch can?

    Just took a better look at the ad. The 12.5 mm was the return line. The hose lines are 25 mm. My bad. May have to get myself a xmas present :)

    Can I replace my CDR valve with an oil catch can?

    Thanks cillman88. I'll do more hunting. There was a link to one earlier in this thread. I believe it said 12.5mm

    Can I replace my CDR valve with an oil catch can?

    I like the idea of the provent, but it looks like the hose size is only about 1/2 inch while I believe the cdr is 1 inch. Is 1/2 inch going to provide enough flow? Also I've seen videos saying that you don't want to route the fluids back to the engine because they contain some nasty things. I'd...

    Time for a new GP harness

    Thanks Phillip1 Looking at the two harnesses offered has me wondering. I know that the engine I put in is a 94 idi and i thought it was a factory turbo. It has the square intake and the cdr on the drivers side valve cover. But the glowplug controller is on the back of the engine, behind were a...

    Time for a new GP harness

    I've had a new fire pop up so it may be a minute before I can go with a new harness. I can use the block heater for a while if i have to. But, I'll be glad to look into Wes's harness. How do I find him? I've tried searching the members list.

    Time for a new GP harness

    When I did an engine swap a while back I also took the harness. But the pin out must have been different. The gp wires fryed right away. Wasn't a problem in warm weather but now...... Anyway, I looked into making my own but with the time it'd take to chase parts and put it together, I think...

    Fuel leak, not the return lines

    That's good to know. But it makes the sudden self repair bother me more. I don't trust things that "fix" themselves that way. You never know when they'll unfix.

    Fuel leak, not the return lines

    I am. I thought there would be inside the fittings. I know there were on the line that ran from the filter to the pump on my old 6.9

    Fuel leak, not the return lines

    Ok finally had some time for the truck. Ever get the feeling that your truck is out to make you look stupid? I drove her up on ramps to tilt the engine back and hit the top with the air compressor. Pulled the filter box and the valley pan was bone dry. Decided to check things out anyway. I put...

    Well, that was disappointing

    Warm up your engine then shut it off. Remove your old fuel filter. Install a new filter filled with seafoam. Start your engine. Let it run for 2 minutes. Shut it off and let the seafoam soak into any carbon for 5 to 15 minutes. Restart your engine. At this point most of the videos show huge...

    Well, that was disappointing

    So before doing an oil change, i decided to try a sea foam hot soak. Been wanting to try it and it sounded like a great way to tick off my neighbor the illegitimate daughter of Satan and Gladys Kravitz. I do the steps and let her soak for 15 minutes. Hop in grinning as I turn her over and what...

    Fuel leak, not the return lines

    Ok, more to look for when i get a change. Been playing catch up with work because of the down time caused by the tranny. Had a little time today but decided she needed an oil change more
