    overheated

    I have a fresh rebuilt 7.3 turbo f250 that I took up a long rough mountain dirt road. I have found out the fan clutch is shot because it overheated idling around at 10-15 kph. When it overheated I was just getting to a lake so I dumped some water on the rad to cool it down, and I left it running...

    Rebuilt engine ques

    I just got my rebuilt sleeved 93 7.3 turbo engine put in and running in my truck. It has massive blow by, and has a shake at idle. The exhaust runs clean with no blue or white smoke. I have a road draft tube on it and the vapor is bad enough to see out the window at idle. Is it normal to have a...

    turbo rod install

    I have a 93 turbo engine that I'm rebuilding, and I can't remember which way the rods go on the pistons. Does the weight pad go towards camside or exh manifold side? I have the rods all numbered so that's good. Also the main caps have numbers with arrows on them, is number 1 cap the front cap...

    7.3 rebuild

    I have a 1993 7.3 turbo engine that I'm rebuilding. The block had to be bored .030 thou over stock to clean up the bore. I had the machine shop pressure test both banks after boring and found there to be a pin hole(s) in no 6 cylinder. The machinist then tells me he has a non turbo block he will...

    Low power

    I have a f350 91 7.3 n/a 4.10 5spd 7300lbs 3in exh, it has newish bb code injectors with 15,000 kms on them, and now a rebuilt 5070 turbo calibrated pump. The compression is good with the lowest 400 and the highest 450. The power with the new pump is quite a bit better off the line but it pulls...

    Engine issues

    I have an 1991 7.3. I just put new injectors in it, and a new return line kit from a good diesel injection shop. I am also running 50% used oil. After I had completed installing injectors and return line kit, I washed the engine out. I cleaned up my shop, and came back to start it about 30 mins...

    White smoke on decel

    I just noticed that when I let off the throttle on my 91 7.3, that it blows white smoke out the exh pipe at rpms over 2000 rpms. I am running wmo, and it runs good on it. The smoke quits after about 5 seconds of decel. What could the problem be? Thanks.

    Front clip swap

    What would be involved in swapping in a slant nose 86 front clip from a brick 87-91 front clip? I like how aggressive the older fords look. Thanks

    Engine knock

    My 1991 7.3 idi is making a rod knock sounding noise when cold but goes away once at full temp. I am running 100% wmo in the truck filtered to 10 micron through a huge filter. I can only hear the noise under the truck and near the drivers door. The noise is most noticeable at the drivers rear of...

    Lift pump issues

    I just installed a lift pump yesterday (mechanical). It was a bent arm one, and was installed in the low cam position. After installing it the truck became quieter, and sounded like the timing got retarded. Did the new pump fail? Do new pumps retard timing from old ones. The pump also looks like...

    Injector ques

    My truck has a chuffing noise through the exh, so I pulled a random injector and found it was wet with diesel, and had bubbles around the copper crush washer. I pulled 2 others and they were dry. I pulled a random injector because I have done pretty much all the engine tests I know of and...

    Zf 5 tranny ques

    I am in the process of getting a zf 5 tranny with everything to do the swap. The truck that it is going in had a e4od with a 7.3. Will a single mass flywheel from a 6.9 work with the clutch components from an dual mass flywheel? Also will the single mass flywheel bolt up to my 7.3 idi? Thanks.

    E4OD problems

    I just test drove a truck that I want to buy. The truck is a 1991 f250 with a e4od. The owner said the transmission was rebuilt 8000 kms ago. The reverse gear takes 5 seconds to come in and feels slushy. The forward gears seem alright but 3rd to 4th revs out to 2800. What could problem be? Thanks.
