Top 5 issues

[silverbullet4x4]

I've noticed though countless time spent reading up on my old 6.0 that most of the problems people have are related to a couple culprits. Since i am slightly lacking in 7.3 knowledge, what are the top 3-5 issues with the 7.3 and good ways to avert them from occuring? Discuss :swordfight:

1. CPS will fail and can leave you stranded.
2. PMR's on big injectored trucks.
3. EBPV hangs closed on some trucks from what I've heard, pedestal likes to leak around it too.
4. HPOP O rings like to leak on older high mileage trucks like mine.
5. Stock compressor wheel likes to surge.
That's all I have right now, I'm sure someone else will chime in with what I left out.

the front ends are kinda junk.. from what i have found

Family has 6 of these things. 2 are tuned and I've observed:
1. CPS will go out. Carry a spare in the glove box.
2. Water pump. Usually like to go out anywere from 90K to 150K.
3. Small oil leaks. Anywere from O-Rings on the HPOP to the charge air cooler boots leaking. Doesn't happen very often.
4. I guess the exhaust gaskets but they leak on every truck we have and I've seen. Some worse than others. Fix is to upgrade to the bellowed pipes.
Thats all I can think of right now. For sure the first 2 happen.

Stock Transmissions. e4od and 4r100 arent known to be too stout in stock form.

Knock on wood... but my stocker shifts firm as hell, I love it. Shifts are spot on and when it's locked you KNOW it's locked, feels bout the same as the tranny locking on my bro's tuned 6.0

 

[GM Duraturd]

They arent bad with stock power....

My 4R100 lasted for a long time tuned on 38's. Then the TC started slipping so I added a billet TC and a shift kit... It's been running like a champ since. This was back in 07...

Top 5 that I've noticed is...

CPS, sticky IPR, cracked or broken MAP sensor/lines, glow plug systems, and...........

Clean oil and clean fuel. Carry a spare CPS, carry a spare relay (PCM, Fuel pump, Heater Fan, IDM etc....they are all the same relay).

Fuel bowl heater likes to short out and blow the fuse (shared with the PCM) it sucks, delete it and forget about it.

Fuel bowl drain gaskets. Same solution, just delete the fuel bowl and problem solved.

Do we both know the same wizard?

 

[JAP]

Do what?

 

[Arisley]

Same thing I did to my stock tranny and it is sitting at 311K now. Sonnax valve and tricumalator springs from David and a HD TC from O'Reilly's.

 

[JAP]

Oh. LOL Yeah. I probably could have gone with a lighter duty TC, but this PI Stallion has done me very well.

 

[Arisley]

I really, really want one of those.

 

[farmall99]

Y'all have been lucky, my 4r slips 2nd and OD bad if I'm in any tune other than stock or economy.

I have a slab of oak attached to the outside wall of the garage. I knock on wood everytime I walk out to my truck. And everytime I get out of my truck.

Andy, would you recommend those parts for a stockish transmission. I need something to temporarily keep my trans together until i get a bts

1. CPS
