Unexpected 7.3 Powerstroke Problems

F350 7.3 with 205,000 miles with major problems

[@muleturbodiesel]

I agree. Looks like you had a sticking or “ leaking “ Injector at some point. I’d see if you can find a shop to test the injectors. Also I’d go ahead and replace the o ring for the dip stick where it goes into the oil pan. They leak commonly and are a pain to change when the motor is in the truck.

The heads will be the most expensive machine shop part. I paid 1100 for my heads to be reworked and took 2 sets of heads to the machine shop. SBI has a complete package of seats guides and valves that will let the heads last a million. Get the rods rebushed, bushings are cheap and the rod on the washed hole especially. Tig weld piston cooling jets. The Ford complete overhaul kit is a good one, comes with new oil cooler. Ive been down this road a few times.

Nice looking truck yet Dennis you get that all put together and it’ll probably go another 20 years lol. I have a 1997 that I drive daily. It’s getting pretty tough looking but keeps going. Thanks for sharing!

[@ronwood7040]

Dennis it is always something breaking down. Nice to see people knowable to fix stuff rather than throw it all away. Ron

[@DLHFarms]

I like to try to fix things if possible.

[@boomersudden6257]

Thanks for the video Dennis. Looks like a ton of work. Not sure I'd want to tackle a job like that anymore lol.

[@DLHFarms]

It’s been a fun adventure haha

[@peterwarnstrom8872]

Dennis, It looks like you got a job on your hands. Best of luck with it!

[@DLHFarms]

Sure do

[@mikeembrey9176]

Good video hope you have a good machine shop👍🏻🇺🇲

[@DLHFarms]

He normally does pretty good

[@casto-]

I guess it’s a good thing you pulled it apart before it went bang😬. Glad I’ve got 5 cylinders in my truck, means 3 less problems 😆🤦‍♂

[@DLHFarms]

Haha what kind of truck has 5 cylinders?

[@casto-]

[@nalley6815]

@@DLHFarmsthey made a Colorado with a 5 cylinder awhile ago. Kubota also made a 5 cylinder tractor. M125X. Everybody says it’s one of the best tractors kubota ever made so it must be a pretty decent engine. That’s honestly the only 5 cylinder diesel I’ve ever heard of

[@JohnJohnson-vx2wr]

Thanks for the video Dennis. Wish I could help you.

[@ComfortablyNumb1969]

I know a couple people that swear by Archoil AR9100 oil additive for these 7.3 fords. It prevents the stiction issue with those injectors. They also love Well Worth Injector Pro Clean for all diesel engines.

[@nicksturdivant9430]

For what it’s worth I think your right on. Been running and working on big equipment for 16 years. I was going to say the same thing you said haha. I’d definitely do the lifter on 7 and I’d do the valve guide seal valve etc . Probably lifer was t pumping up fast enough. Good luck love you videos 😎😎 PS I’d also check the oil passageways on the head block etc for that lifter on 7.

[@DLHFarms]

Good thinking on that oil passage way

[@mikehors7351]

Hi there do not forget to reset the truck computer when done.

[@imagoodlistener2730]

Do yourself a favor. Get rid of them PMRs. Get some crower rods. Welded oil squirters as well. If you dont know. Look at Riff Raff diesel for OEM parts.

[@noelhohberger1188]

Still a nice looking truck

[@DLHFarms]

Thanks

[@warrenpatton5138]

Hello from Bristol, hey Dennis I had a 01 f250 w/ the 7.3 and loved it. I had it paid for and got the bug and traded it with 121,000 on it. Still wonder if I did the right thing but, oh well. I believe you’re doing the smart move by rebuilding it. It’s hard to beat the Cummins tho. See ya on the next one. Warren

[@DLHFarms]

I guess the question is, what did you trade it for. Haha

[@warrenpatton5138]

@@DLHFarms I traded for a ram 1500 Laramie crew cab gas 5.7 hemi. It’s done a jam up job so far tho I wish I could’ve found a Cummins but few and outta my $ range around here. Insane $ with 300-400 thousand miles and roached interiors. I can still dream tho, maybe one show up someday just for me. Take er easy my friend see on next one. Warren.

[@DLHFarms]

Trucks prices have gotten ridiculous

[@Bear-pu2qo]

Looks like you might of had some floating lifters also, some of the reason for the mushrooming of the rocker arm. Be sure to check your push rods for straitness also. I would just replace all the lifters.

[@ihus9950]

Dennis, that's not going to be a cheap fix, how's the Crankshaft look, rocker arm ware from being loose I'm thinking. 👍🏻

[@DLHFarms]

Crank still looks good. All the bearings looked good for 200k miles

[@alsaku33]

How would I know if I have a leaky injector? Truck runs great, compression is good. Just upgraded injectors about 2-3k ago. Any knowledge would be greatly appreciated sir!

[@DLHFarms]

I would watch for a rough idle that’s all the symptoms mine had. I just kept on riding it like that

[@Northeastohio]

Wasn't that truck kinda dark blue?

[@DLHFarms]

No it was always burgundy with metallic

[@danst.pierre1368]

Couple of things that looks dusted also #8 injector stock has a different part for a fuel knock noise make sure they replace the injector cups in cylinder heads and check #3 rod if it had excessive fuel they are common to bend if the injector leaked

[@DLHFarms]

I knew about the different injector in 8 and it is the correct injector. Where do the rods normally bend at?

[@danst.pierre1368]

@@DLHFarms if there was fuel in cyl due to lack of clearance between cyl head and pistonthey will hydraulic not sure where I’m sure the machine shop could check for it hope it helps

[@dougbrewer2257]

When you get the 350, I thought you had a Dodge😊

[@DLHFarms]

Had the 350 since 2003 bought it used with 40,000 miles it was my daily driver before the Ram. Got the Ram in 2017 and been driving it since but use the Ford as a spare truck and a Farm and Hay delivery truck.

[@tonycummings3610]

Hey Dennis I enjoy your watching your videos, I’m a young hay farmer my self and I wanting to know if by chance I could ask you some questions to future enhanced my operation. If by email or phone call

[@tonycummings3610]

If you had to pick a better setup to start with when making square bale would you rather have us use the Steffens system or Kuhn setup. With the accumulator and hay grapple

[@justinwatch]

kzbin.info/www/bejne/lZrFmGedYrSpmNUfeature=shared LS George works for cleetus McFarland and in this video he mentioned either pull in the cab or else the transmission to get the motor out. May want to drop that transmission. Just sayin.

[@threearrowsfarm636]

How many miles on this old 7.3?

[@DLHFarms]

205,000

[@nalley6815]

That’s weird for the rocker and valve tip to do that. Usually when lifters are the cause they’re beat up pretty good. I wonder if something got in there and got between the rocker and valve. I could be way off here but that’s just an observation. Looks like a pretty nice truck though. Glad to see you putting videos out sir!

[@forestlawrencegrading9154]

Just tell them Sasquatch did it⛽️🇺🇸

[@onehappyfarmer3461]

I know about as much of the internal workings of an engine as Biden does running a successful presidency. I never heard of a 7.3 having any issues. We got a 02 and all I ever done to it was replace the alternator. It’s funny how 20 years ago all you ever heard was put on a cold ram air filter and now mechanics are saying throw them away. Glad I never went that route now.

[@DLHFarms]

I know right that was the thing back in the day was k and n air filter

[@nickwhitaker9890]

Appears the problem is, a lack of chevy 😂

[@DLHFarms]

Bahaha! I think the air filter let a Duramax get sucked up in there

Ew a Chevy. Never had any luck out of chevys. Cheap made interior and snapped cranks isn’t for me.
