    Cold no start issue when sitting awhile

    We have a 03 7.3, if the truck sits for a couple days or more, it doesn't want to start. Sometimes it eventually starts, sometimes ether gets it going (I know I know..), and sometimes ether won't even fire it over. Once it starts, it will run fine and start anytime you need it as long as it's...

    99-04 steering wander

    My 2000 is all over the road, mostly at highway speeds. Any tricks to fixing this? I've installed a Bluetop steering box and replaced all front end parts that had play. The only thing I haven't replaced are the track bar and leaf spring bushings, as well as the steering stabilizer. I just want...

    Brake caliper locking up on Superduty

    I'm trying to figure out why these trucks go through calipers so often after the originals go up. These trucks have been out 20 years, has anyone found the reason behind this? I've read so much and no one knows (old posts). My assumption is heat, dust, and rust from junk pads and solid rotors...

    99-04 front airbags

    There's a company named "Airbag It", they make a 3-link setup on bags to replace the front leaf springs. I'm not sure if this is old news or something new, but has anyone on here tried it? It's about $1600, and yes I'm aware an 05+ swap can be done cheaper but I rather have something that's 100%...

    Vacuum pump constantly running

    I haven't hooked a gauge to test for leaks yet, but I did plug the red line running to the ESOF solenoid since that's a common route for leaks. I also used my fingers to plug every open inlet/outlet on the pump itself and it still wouldn't shut off. Is it possible the pump could be bad if it...

    Intermittently cutting out

    My grandfather has an 02. He told me it was randomly shutting off, so I replaced the CPS with a new OEM one I had. Started it, drove it a little and no issue. Next day he said it was still doing it, so I take it for a long ride and it was cutting out and throwing the CEL and WIF light, then goes...

    Exhaust backpressure sensor T'd into the MAP

    What else does the sensor control besides the EBPV (or send a signal to)? My neighbor T'd his into the MAP line and said it was day and night, including crisper shifts. I didn't want to believe him until I typed it in Google and saw people saying the same thing. I'm just curious what it's...

    97 F-250 7.3

    Pretty much everything about the truck is in the ad. I started to build it which is where the supporting mods come into play, but has small injectors and stock turbo. Other than all the parts listed in the ad, it had 238/100's and T4 mount with s366 and later a s475. I returned to stock soon...

    Opinions on 5" exhaust..

    Sorry guys I know this topic is old and probably annoying but I'm looking for the best possible sound with FULL exhaust (no side pipe, no stack, etc). Youtube hasn't done much justice and nobody around me has 5" on an OBS. My 4" straight pipe is really quiet for some reason, and has more exhaust...

    7.3 parts

    Custom 3" intake plenums $120 shipped OBS s300 downpipe for T4 mount (not Irate) $100 Fresh valve body with Trans-go springs and I believe valves also, .500 modulator sleeve. Never installed and can include the rest of the Transgo HD2 shift kit. Just the accumulator parts were used. $150...

    Turbo exhaust housing to collector flange bolt size?

    Can anyone confirm that 10x1.5x30mm is the right size? I'm getting 4 new bolts and not going through the dealer. Someone on another post said that size but didn't seem to sure

    Mild build obs 7.3 trade?

    Not sure if trade ads are considered feelers, if so then ******. I have a 97 ECLB 4x4 with almost 248k miles, needs paint, no major rust other than a couple small spots over wheel wells on bed. The interior isn't bad but the carpet could be cleaned. Good running truck, it was intended to be a...

    OBS T4 mount trade for stock mount?

    Probably a long shot but anybody local to Maryland that would want to trade their stock obs turbo stuff for a T4 mount plus cash? Currently running a s475 but also have a newer low mile s366. Mount was built by Adam at Strokers Unlimited, will come with up-pipes, plenums, intercooler (unless you...

    s475 with 238/100's

    I just put a 75/83/1.0 on my truck. It doesn't seem to pull much harder than the s366 that came off it, just a little slower to spool.. Are 238/100's just too little of an injector to completely spool that size of turbo, especially with having a 1.0 housing? Or do I might have a boost leak...

    02 headlights only work on high beam

    Trying to help my grandfather fix a problem that has come and go, but now a permanent issue. The trucks running lights, fog lights, and blinkers work how they should. The high beams work when you hold the blinker/high beam selector back but not in the locked forward position, and no low beams at...

    Muffled 7.3 sound

    Probably a waste of a thread, but does anyone run straight pipe yet the truck sounds muffled? My 97 has no exhaust note to it, no crackle, no nothing. Just curious because my previous 97 with full 4" sounded amazing from in the cab, the one I have now I've tried full 4", 5", now axle dump and...

    OBS T4 mount 3" downpipe

    Anybody with hood stacks have their downpipe laying around and aren't going to use it? I need a 3" one as my 3.5" DP got converted into a pancake trying to clearance it from the firewall which has also gotten reconstructed..

    Let's talk shift

    I'm by no means a trans builder, I've never pulled a trans apart. But I've messed with valve body's in e4od's and 4r's over the years between owning them, reading up on them, doing mods, etc.. I can't stand a smooth shift, but nobody wants to be in a neck brace after driving their truck either...

    Standard duty fan clutch?

    I put an electric fan on my truck to get me through winter since my last 2 fan clutches seemed to stay 100% locked (fan roaring with increase in RPM). The last fan clutch I bought said severe duty, but I didn't figure that out until after I installed and noticed the roar never went away.. Since...
