    building a 1997 F350 cclb 7.3L 4x4

    You'll be limited with the OBS tuning unless you get a custom tune to what mods you decide to do. IMO I would do gauges (boost/EGT/trans) first, then add a 4" cat back exhaust (diamond eye w or w/o muffler) and a hydra chip with the tuning of your choice (totaldieselperformance). After doing...

    surging at road speed, more noticable with cruise on

    Much better off just eliminating the exhaust valve. First mod I did to both of my trucks within hours of owning them. Never looked back.

    HELP!!!!!!!!

    Do you know the condition of the glow plugs? If not, you should pull them and inspect (or replace for under $100). I've seen glow plugs test "good" with a meter, but when 12v is applied they hardly glow at all. Is your block heater working? Have you tried plugging the truck in for at least 3...

    2003 7.3 power stroke shuts off after 15 minutes

    Did you replace the pigtail when you installed the new IPR ?

    HELP!!!!!!!!

    I've never removed/replaced the dipstick on either of my trucks so I've got no advice from experience.

    Help. Slow start after accident with tip over

    probably going to take some driving to purge the HPO system of air

    surging at road speed, more noticable with cruise on

    What is your fuel pressure at idle? under load? Has the regulator ever been rebuilt? Has the screen at the regulator been cleaned?

    Drive train experts...please step inside!

    good point about the clutch fork. Known issue with cracking. The OP could remove the slave cylinder and measure the distance from the bellhousing opening to the fork. I'll have to look around for the correct distance on a working fork.

    Help. Slow start after accident with tip over

    How many miles since the accident? Could have some air in the HPOP system from the tip over.

    HELP!!!!!!!!

    If you're certain it's at the bottom of the pan, it *probably* won't hurt anything. I state "probably" because although the pan is deep, there's still a round metal disc where it doesn't belong. I would most worry about it getting sucked up against the oil pickup tube. You could try going in...

    How to locate misfiring injector

    remove both valve covers with the engine running look for equal amounts of oil coming from the spouts on each injector indicating they are all firing the same. there should be no oil leaking from the top part of the injector to disable an injector, unplug the two wire plug going to the...

    Hard start white smoke

    That's your problem. Fuel pressure should be almost "instant" when cranking with a correctly working mechanical fuel pump and regulator. How old is the mechanical pump? Has the regulator on the fuel bowl ever been rebuilt? Personally I prefer the mechanical pump on the OBS compared to the...

    no inspection port on a SD truck

    Drive train experts...please step inside!

    pull the transmission and inspect the clutch/flywheel. You've got a 2wd truck so it's pretty easy even if you leave the truck on the ground.

    Hard start white smoke

    If it started the same with the auto PCM that is a fair enough test to confirm your PCM is not bad. The truck probably threw a bunch of codes for the missing auto transmission sensors. I'm confused now. Earlier you said it started have problems after installing a chip? Now you've gone through...

    Drive train experts...please step inside!

    Can you post a video of the problem? If it's the dual mass flywheel and it fails catastrophically it can take out the bellhousing or crack the transmission case.

    Hard start white smoke

    I still think it's something to do with the chip, since you said the problem happened immediately after installing it. Can you get another unmolested PCM to borrow and swap in? Also the IPR could be the issue. Just because the PCM is asking for a certain duty cycle, doesn't mean the IPR is...

    original clutch? dual mass flywheel could be on it's way out

    Hard start white smoke

    So... have you run the truck with the chip removed ?

    mv446 to 7.3 bolt up

    What is a 79 5+4 ? The bellhousing bolts on the block are the same whether it is a 7.3 IDI or 7.3 PSD

    Accessory circuit won’t turn off

    SD are different than OBS in that accessories stay "on" until the door is opened

    2003 7.3 power stroke shuts off after 15 minutes

    Could be IPR solenoid getting hot and quitting. Could be o-rings leaking when "hot" Can you monitor the truck and log what's going on when it stalls out ?

    Plug for heater

    Do you know the service history of the glow plugs and relay? If not I would replace all 8 glow plugs with OEM and upgrade the relay to the larger stancor unit.

    Plug for heater

    The power cord goes to a block element near the oil filter. The cord can be purchased new or the old one can be repaired. If you're glow plug system is working correctly, there really isn't any need to "plug the truck in" to warm the block. I've started at -20F with only glow plugs.
