This guy is just not afraid to get in there and do the tough jobs that no one wants to tackle. Amazing mechanic

[@stans9487]

I wish i had a crew of good dudes to come over and whip some shit out like that. Its nice to see. Im restoring my 96 psd. Complete. With lots of power upgrades. May as well rip out/ upgrade old exhaust. Im glad my baby leaked juice as much as she did over the yrs. The oil preserves! My starting on driver side manifold removal has just begun. I estimate 30 hrs to get that thing off and old studs out. Im a 50 yr old stone mason. This is not my "thing". Thank u for the visual aid. Mucho respect✌️

[@superspeed2956]

For sure saved me a bunch of time just went ahead and cut all the bolts made everything easy from there!

[@AutomedicGarage]

That’s the only way to do them in my book. Thanks for watching.

[@marcbayne6748]

Tackling this exact same project (manifolds, up pipes, EBPV delete) on my ‘02 F350 tomorrow. So glad I found your video. I was dreading the manifold bolts, not so much anymore. Probably going to tackle the valve cover gaskets while I’m there if they’re leaking. Thanks!

[@AutomedicGarage]

Glad it helped. Got some other good 6.0 and 7.3 content.

[@nickclair1388]

I get too mad working on my truck, I've gotta pay someone else to do it 😅

[@nickk3765]

Thank you! Quite possibly the best video I've ever watched on the internet.

[@AutomedicGarage]

Glad it was helpful! Thanks for watching

[@bosleepsaround]

This video is the BEST cut 6 bolts and extracted 6 no problem that extractor tool might be my new favourite!

[@ricks5984]

Truly informative and easy to understand. Great job, well done.

[@santanaspooks7595]

Great video! Me and the husband are tackling our 7.3 in the morning! She has 570k and need some loving! After seeing this the hubs finally agreed I was right about cutting those damn bolts!

[@AutomedicGarage]

Yes, cutting is the only way to do this job without shearing off bolts. Glad it helped. Thanks for watching.

[@davem3789]

Great video. What you found in that new pedestal is why I modified my existing one to delete the EBPV.

[@scoobysgarage5263]

Gotta say that bolt extractor is money! I used a 50/50 mix of acetone and ATF to soak my bolts for an hour and i only had to cut one. Went really quick vs having to cut every single one. Old trick i learned for exhaust too is to first tighten for a couple impacts then loosen. I belive this works cause it breaks rust but doesn't jam it in the direction of loosening and you have a little momentum. These manifolds had 266,000 on them mix of New Hampshire and Colorado so not rust free.

[@AutomedicGarage]

Yea, cutting doesn’t take long, it’s my go to for doing these. I believe the truck in that video was 400+ on the mileage. Usually only see them leaking with over 300k due to so many heat cycles.

[@TPM517]

I’ve always been unlucky. Lol my 2001 only has 255 on it and have a passenger side out. Local shop wanted 3k. your video gave me the confidence to do it myself thanks!

[@AutomedicGarage]

@@TPM517 that’s a sky high price. Glad the video helped.

[@markramich8926]

The whistling that you’re so wanting to hear is coming from the turbin wheel, not the compressor side requiring a large straight pipe exhaust system

[@AutomedicGarage]

@@markramich8926 I’m not wanting to hear anything, I was diagnosing the exhaust leak from the manifold. It’s a work truck and not my truck at that, no need to make it a hot rod.

[@austinsonger7030]

Started doing up pipes on my 7.3. Bolts that go to the manifold flange would not come out, I feared I was gonna have to pull manifolds but after I watched this video it was cake. Thank you! Although I bought a stud puller from orileys and it broke the teeth off inside 3 different times after swapping it out, finally I went to advance auto and got a diehard version of it and it got the rest of them out like butter! If I ever do another 7.3 I’ll definitely be doing it this way! Thank you!

[@AutomedicGarage]

Sure thing.

[@refinersforge1781]

Thanks for the video! About to do this on my 96 F350

[@AutomedicGarage]

It’s not to bad. Just take your time

[@nickclair1388]

Bro, loved the bolt extraction, that was skilled! Had me on the edge of my seat 😂 I'm having this done here soon on my 2002 F250. New stainless tube headers, new bellowed up pipes, new non ebpv pedestal, KCX300 turbo, new Sinister intake tubing, new diamond eye 4in downpipe. Nothing special really, still fully stock, just some new part love for my 295k mi 7.3. My baby, lol, showed her more love than any girl I've ever dated 😂 LOVED the videos guys! Quick question for you though? In terms of labor cost, how many billable hours did it take to do the whole exhaust replace? Trying to see if how long that took you, was close to my assumption. I'm sure this shop I'm using won't be too thrilled about the header replacement on my truck, but it's gotta get done! These new headers are sick! Makes me wish I had bigger performance parts on my truck! I'm not trying to have a race vehicle though. God bless you guys! Thank again 😀

[@lowwarden9958]

Thank you for the video I'm about to tackle mine because I hear that noise and I have exhaust smoke coming from my hood twice when trying to cold start but not when I start it regularly so that'll be a fun project for later on 👍

[@AutomedicGarage]

Make sure it’s not your up pipes

Really great video alot of info resume in 1 video

[@alsaku33]

I really need to do this job...down pipe is new, up pipes are new, upgraded turbo, etc. but just didn't want to do this job couple years ago. Now I have exhaust smell in the cab on cold mornings with the heater on...god damnit!

[@robertfisk8344]

That looks like a helicoil down in the intake runner other than that great job keep the videos coming

[@AutomedicGarage]

I’m wondering what would have gotten helicoiled above the intake plenums to allow that to get sucked down in there.

[@swolenation8432]

Machine shop to plane the manifolds that prob cost more than the stainless manifold/header you can get with gaskets for 240 dollars that seems crazy

[@earlsmith3894]

I was told to you could run those manifolds without the gasket as long as their brand new out the box.heard they will bond together!

[@AutomedicGarage]

You can, but why not run the gaskets to help prevent the leaks in the future?

[@Marathon13240]

My truck has nearly 190k on it and i think my driver's side manifold is leaking 😭 i just did bellowed up pipes, ebpv delete + high flow outlet, chipotle mod, and a few other smaller things and my exhaust tick is still present, made sure my up pipes were good and straight and tight. My truck was down for a week becuase fedex was a week late with my pipes. Not looking forward to doing the manifolds 💀

[@Pipeline-surfer1]

Great job,, how much would that cost at a repair shop ? Not a dealership..

[@AutomedicGarage]

We charge $600 labor at the shop.

[@cconditt]

Great vid! I need to do my E99. Over 300k on em. Not looking forward to it either

[@AutomedicGarage]

It’s not a terrible job, just takes a little time and patience. Thanks for watching.

Great stuff bigtime, Thank You!

[@nicholasmarioncunstruction]

Will 99-03 manifolds fit on a pre 99 7.3? They have some stainless exhaust manifolds on ebay but i cant find any for a pre 99 7.3.

[@frankhartford5194]

I usually cut them off with torches or plasma cutter. Most time I change the manifolds to

[@AutomedicGarage]

I prefer cutting with the cutoff wheel because you aren’t worried about slag and heat messing up the wires or plastic. I guess you missed the part where I showed and install new manifolds. Only way to reuse the old ones is to have them run on a planer to make them flat and seal with the gaskets.

[@williamvincent8920]

Great job

[@pereztrucking4869]

Are those gaskets the same if u flip them over ore they go on one way. Nice video

[@AutomedicGarage]

They appear to be able to go either way. There is not out or in label on them.

What’s that plug in the back of the pedestal ? Did you cover it yourself or does it come like that ? Didn’t even look

Usually comes with a plug in it but on occasions found them not in or not tight. So always check.

[@user-hg4pk2cy7k]

I see you cut every stud bolt off rather than trying with heat or a wrech😢.. have you done this before knowing that they will be seized or just heard this was the best way to

[@AutomedicGarage]

They are seized in the manifold not the head. Cutting makes it easier.

[@denniswattenburger1260]

Are you using anti-sieze or Thread- Lock on the bolts?

[@AutomedicGarage]

Def no thread locker. Anti seize would be ok to use but is pointless. They are exposed to so much heat it will just cook the anti seize off.

[@liam6685]

Does anyone know what bolt/stud is used in the 7.3 idi?

[@AutomedicGarage]

Not sure, never had to do this job on the old IDIs. However I wouldn’t be surprised if it’s the same.

[@LoLoNationalForest]

Do this before the up pipes?

[@AutomedicGarage]

Not necessarily, if it’s a squealing screaming sound especially during acceleration it’s up pipes, if it sounds like a traditional exhaust leak it’s the manifolds.

[@midnightmachineshop]

Out of curiosity, what is the ballpark cost (parts/labor) for the manifold replacement?

[@AutomedicGarage]

$1000 labor, not sure on the manifolds, gaskets and bolts. It’s been a few months since I did one. I wanna say it was around $200 for the manifolds.

[@troystevenson4090]

Do you have a link to the stud extractor you used?

[@AutomedicGarage]

I think I listed the OEM tools part number in the video. When I get back to the shop I will get the number off it and message you back.

No the truck wasn’t but she definitely was down on power and took a long time to spool as you can imagine plus the annoying exhaust clatter.

@@AutomedicGarage yeah it's a new new tube and it's a deleated pedestal in all honesty I'm going through the whole thing replacing all the sensors and such just to catch up on it I've got other 7.3s but this one has to be the E manifold I've already replaced the up pipes. Also the oil cooler/heater was blasted with soot and I recently cleaned it like 3 months ago... it's probably a combination of worn out injectors and a leak I just hope I'm not dealing with snapped bolts... better buy a new set of headers... and a everything reinstall kit.

Looks like a helicoil

[@AutomedicGarage]

No heli coils on it. Warped exhaust manifold gaskets is usually the case with 7.3 diesels.

[@2xeverything]

Is this an exhaust leak? Just finished doing the oil pan but didn’t disconnect any exhaust parts before jacking up the engine and cab. I did replace the up pipes with billows a while back. kzbin.info/www/bejne/d4q6eZqAdrSohLssi=JkLzns1AIND37vfX

[@AutomedicGarage]

Hard to tell if that’s a squeak or a squeal. Does it change with rpm’s? If it is exhaust it’s coming from the up pipes. Check your up pipe to turbo connection and your bellows for leaks.
