[@Dogghousse]

Wrap your manifolds up pipes and down pipe and turbine with a good exhaust wrap, it does 2 things first it keeps the heat in the pipes allowing the exhaust to flow better by not bleeding off the heat in the pipe and cooling effecting the flow of the hot exhaust gasses. Second it keeps residual heat from going into the engine bay roasting your precious o rings!

[@billmalec]

When you said you didn't mod, you got my full attention. So tired of these guys with SDS doing nothing but mod vids. Thank you.

[@treysmith6407]

Good video with great advice but, just fyi You can not "burn up" a 7.3l Powerstroke by running it out of oil. The fuel system is actually driven by the high pressure oiling system. When a 7.3l gets about 1.5-1.75 gallons low the engine will starve for fuel and die. Then crank and crank and crank but not start due to no fuel. Ask me how I know😅

[@johnny9577]

My 7.3 has 320K running strong, changed injector cups and injectors. Runs like a champ.

[@ThePeyton301]

From a guy that has the general motor disease. You did a great video.

[@vincebotkin1960]

Two items you need to know about on your 7.3 Over time the injector electrical connectors under the valve covers will start to separate then you have several cylinders not firing. Simple fix. Remove valve covers push the connectors back together and put a couple small zip ties to hold them together. Under your fuel filter you will notice a threaded plug pointing to the back off the motor. Driving through the middle of Texas in the middle of nowhere this plug backed out a hair and was blowing oil everywhere. A 5/8” socket gently tighten it up and was able to limp it to a campground and ordered the seal kit from Ford was back up and running. Both of these fixes were told to me by my friend a Ford diesel mechanic by saying the symptoms over the phone.

Donaldson makes valve cover gaskets with wiring that plugs in outside of the valve cover gaskets . Well worth the couple hundred bucks to do it

Another good one is to swap out the upper radiator hose for the dual alternator one that route around behind the belt instead of thru it so you don’t have to drain antifreeze to change out the belt

[@HorsepowerPonies]

Then belt goes and take your hose with? Seems like a downgrade to me

Yes plan stock original glow plugs. Yes i use my stock plug in block heater for winter months here in northern Indiana. Motor lasted longer than the trans. And 5 clutches. Had to put new rear end last year. I love the 7.3. Change oil and filters. Fix stuff as soon as shows up ans they will last a million miles.

[@edwardrook8146]

@@HarrisonCountyStudio I'm pretty sure glow plugs mostly die from firing the engine before the glow cycle is over

[@Dogghousse]

When its cold out your glow plugs stay lit for a maximum of 120 seconds you should get a good voltmeter that plugs into the cigarette lighter so you can watch the voltage jump back up when the relay kicks off. or you can wire a led light from the relay to the cabin that way you know the glow plugs have completely cycled off. In the summer time they dont need to cycle so you can put the glow plugs on a switch so they don't come on when they dont neccesarily have to. Also upgrade your grounds from the alternator to the battery to the body that way the passenger side battery shares the grunt of the work with the main battery. It will also extend the life of your alternator

[@BrianW._1313]

4 gallons..! minus 1 qt. and you can't burn the motor up just from blowing some your oil out due to a ruptured line. cuz once it loses about half of the oil it will not run. period. because there's no oil for the injectors. the valve train might suffer a bit and the high pressure pump might see excessive wear or fail completely, but you're not likely to spin a bearing or throw a rod or anything like that.

[@Mikefngarage]

OK well Just wait for it to break in the middle of the desert. or run your high pressure pump dry....Useless comment. IMO

[@mitchelledwards5219]

Get a stancor/white rodgers glow plug relay. Its one of the only aftermarket sensor/part you should upgrade to, that relay is a lot more stout/beefier part than the original equipment piece.

Actually that 7.3 is a much better Diesel engine than that Chevy diesel you have. ... and the new F250 6.7s are probably the most comfortable, best performing, diesel trucks on the road. I’ve driven the Chevy and the Ford 6.7 for work, I own a 7.3😉

[@veraciouspatriot4297]

Great vid! You helped clarify some things for me!

[@travisnorton9288]

You said it but absolutely don’t know that your fuel pressure is dependent on your oil pressure so if you run to low on oil the motor will just shut off

[@magmomwise]

From my past experience with the 7.3l engine, the injector o-ring usually will need replacement when your engine gets to about 150K mileage give or take. The o-ring deteriorate due to the high pressures in the system and engine heat. Also you must use the correct engine oil and it is helpful to use Ford Motorcraft Anti-Foaming additive at each oil change. The other common issue is the valve cover gaskets have wiring harness connectors in them for the injectors and glow plugs, these will burn out over time due to the high amperage draw of the glow plugs.

[@camposvazquez]

Please can you list the Ford part number for the anti foaming additive... Thank you

[@Velvethamma]

I have or have already repaired all those problems. Always chasing oil leaks and fuel leaks. Plenty of o rings to fail in the 7.3

[@Mikefngarage]

yea those oil leaks really suck. But better than buying a new truck or new ford. the one you have is great for plowing. Watching you one night

[@edwardrook8146]

You're right I've never seen so many bad O rings in my life... But I like my Ford I don't care if it's parked for repairs all the time :)

[@jeffreyeudaley1370]

Like the last comment you had but you don’t know what you’re talking about not to be on remain 7.3 is hydraulic and electric injectors the high-pressure oil pump if you get down a gallon or low or shall I start chugging like almost like a big radical camshaft in a gas motor and you get down much lower and that it won’t run at all because The high-pressure oil pump will not make enough pressure to fire the injector so your engine will die before you spin a bearing that’s one of the reasons decisions almost bulletproof

Hey, From now on, I'll do my own maintenance on my new ''used'' shuttle bus 2000 with a 7.3 powerstroke. I bought it 2 years ago, but it's been running only once in a while on my own farm land, just to get it running at least once in a while (lack of time). I have 2 young kids and I want to use it as much as possible for rv during winter. Winter is really quiet for me cause my job is really slow, so I can visit family or travel a lot. I got a pretty strong background in mecanic (DIY). So could you refer me to a few good KZbin video for maintening a powerstroke.

Look up powerstroke Ron (R.I.P.). HE WAS THE GURU OF THE 7.3 POWERSTROKE. I learned more about how the 7.3 works and act's when something is amidst (wrong) then any other channel. Powerstroke help would be my second choice. May Ron rest in peace, he will be truly missed. One word of advice, go online and order you a good ELM Bluetooth adapter for your OBD2 plug in under your dash and download car gauge pro from the App store. These 2 things will allow you to read all your sensors, ( ie: H-pop pressure, oil temp, ICP duty cycle, trans temp, boost, etc.. ) along with reading your DTC'S (diagnostic trouble codes), clearing the DTC'S and check engine light. You can also run a BUZZ test on your injectors, run a cylinder contribution test, do real time data logging on the motor too. It's really a must have if you're going to be working on your 7.3 yourself and keep it in top notch running order.

I think it is more for quicker warm up. The exhaust flapper. Many guys remove that because it restricts flow after it is warm I dont know how it would make it start better when cold. That would be the glow plugs or injector oil pump pressure.

[@norman_sage2528]

@@Mikefngarage If you choke the exhaust, it increases the combustion chamber pressure in the up stroke which increases air temperature to start combustion. Have you ever heard of people stuffing a rag in the tail pipe to get a cold diesel started?

@@norman_sage2528 IMO super bad R and D. why does every other diesel start up easily only the My other truck with a duramax started up at 3 degrees first crank no block heater same compression ratio. Many people are taking that thing off and it does increase HP. Another fail of the Intertrashional diesel.

[@Mikefngarage]

with it on or off my that truck still requires more cranking than any other diesel I have ever owned. Never had a cold start issue and I have had several never needed to put anything over the exhaust of any truck I had only fords.

[@omgbbqcia911]

it always amuses me to hear these "all other diesels besides my diesel suck" arguments. whether its the 7.3 guys hating on 6.0s 6.4s 6.7s etc or LLY Duramax guys hating on the LB7s or 12 valve cummins guys hating on 24 valves. all diesels have pros and cons. strengths and weaknesses. some you can neglect, some you have to maintain more. the best diesel is the one that you personally like.

If you want long gibbet I out of the 73 I suggest you do a few other things one as you change out your air filter to either K & N or S&B Then go to insane Diesel and get there oil bypass filter witch holes down to 1 Micron and also get BD diesel CCV mod with filter and oil catch can this will keep oil out of turbo and intercooler these 3 mods will cost between $850 to a $1000 o have all 3non mine and they work very well with the insane oil filter you only have to change the oil every 15,000 miles it does a very good job of keeping oil clean I changed my oil 3000 ago and still can seen through it

My family has 2 7.3s and a 6.7 they are all gpod

[@jesserebel8387]

sorry to bother, I put new o rings in my hpop and new lines. 2000 7.3 t truck had a no start found a blown fuse maxi number twenty four. replaced fired up, ran for five mins, reved it and it died. No start after that. checked everything could find nothing. finally I noticed on the directions for the new lines and cross over line, it mentioned to discard the springs and check valve under fittings for lines on pump. seems the new fittings are different inner diameter and the springs don't fit in the fittings like on the original. I belive by not changing the springs and valves, that I may have literally torqued the spring down when I installed the oil line fittings. This is a three hose kit with bolt on hoses not snap on. Anyway I checked ipr, looks great , not sticking from what I can tell , I pushed on the piece in the center while spraying with brake fluid and id didn't seem to stick at all and seemed to open and close the ports as I would expect. I did a test on the solenoid for ipr it had an ohm reading of 11.3. I just now removed the spring poppet check valves. Have you ever had a problem like this? any suggestions? my resibour is full, i also removed the icp sensor and turned it over prior to removing spring poppets and it was just barely any oil coming like a half quart max on a long crank with that icp sensor removed. i also ran 12 volts directly to ipr and turned over no start. My theory is i basically dead headed the pump by bolting down those fittings with the spring poppets in. I haven't attempted re start yeti thought i would attempt to confer with you first . thanks a lot

Ummm the 6.7L power stroke does not suck!

[@Mikefngarage]

UHHH CP4 that cannot be converted to cp3. early turbo problems Ceramic bearings, LIfters collapse....DPF plug ups. There are too many to list. My buddy who hauls for a living finally bought a Duramax 2 years ago and all his problems went away put over 200k miles on it already has 400k miles..... just saying.

[@FordFan01]

Anyone that says the 6.7L sucks has never placed a finger on one. Theres a reason its been around even longer than the 7.3 was.

[@michaelhooker2635]

Except this yea D-max would grenade the fuel pump and ruin the entire fuel system about every 30,000 miles. Then you want to talk new D-Max, GM is currently being sued for their shitty transmission. I’ve seen many 4R100’s last 350,000+ miles without ever doing anything to the trans.

Losing oil wont ki the 7.3 bud your hpop will shut down the injectors to safely stop your motor before damage

[@allentompkins4063]

YOU HAVE TO CHANGE TOP END OIL IF YOU WANT HIGH MILEAGE OUT OF YOUR INJECTORS ...3 qts of top end oil is only topped off but never drains at oil changes so eventually you have tons of carbon in your top end oil being used to hydrophilic open your injectors causing severe wear @ @ @

good one IDK why they dont have a easy drain for that seems like they missed something on engineering school that day.

Changing that .75 in the oil reservoir is a waste of time, it only amounts to about 5% of the total oil volume. There's always 2 quarts left in the heads which cannot be changed out anyway regardless of what you do. Just change your engine oil every 5k with quality oil and you'll be fine.

IT'S not a MOTOR ! It's an ENGINE !

[@super6954]

I live in Canada an engine is commonly called a motor and the same in lot's of the USA. I grew up in the U.K where a motor was electric, and anything using fuel was an engine. Lots of things use different words to describe them here, like a brake disc is a brake rotor. mud guards on a tractor are fenders, tire is not spelled tyre like in the U.K either .

[@handyman432011]

Your pistons don't crack from heavy polling they crack from the heat because you're not letting your engine cool or you're running too high RPM or speed up the Hill everybody tries to go fast up the Hill which gets all that Exhaust temperature up there and that's what causes your cracks with these engines any large engine that you're pulling read once you stop you need to let it cool down for 10 or 15 minutes because you can melt your Turbo blades and you can Other parts people forget sometimes that these engines are not all steal your pistons are aluminum there's other aluminum parts and their and their steel in the all of they heat up and cool down in different ways woman heats up faster steel heats up slower steel will hold the heat aluminum will cool off faster

This guy clearly has not idea what hes talking about. Ive never had a issue 4r100 transmission even with adding more power to my truck. They are solid transmission. And btw if you only have 3 gallons of oil in your 7.3 your super low on oil. And injectors on the motor are just fine.

[@jameshubbard7720]

Can't say 6.7's are the best, they just haven't been out long enough to determine the longevity and reliability of the engine for the long term. ( ie: million miles plus 22 years of service like the 7.3's ) They are good engine's, nevertheless we still have to wait and see if any catastrophic weak points show up down the line, say like 3-500,000 mile mark.
