Phil, thank you for promoting the T.T.S. project!!! That was awesome of you!!! I really appreciate it, we all do!!!
A great Video my friend so awsome i love it pleas keep up your great work Phil 👍🤟😁🛠
Great video brotha. Nice improvising. Pretty interesting to learn that Cat engines need 900 psi of oil, lighter duty diesels only need 500. Thx for the shout out.
that sure was a slow crank for temps in the 30's. might be time to get some fresh batteries there phil! it cranked slower than i would like even after it had been in the shop all that time. huei with a hard hot start surprise surprise. i would want to plug in the lap top and make sure the "actual" pressure your manual gauge show is the same as what the ecm is seeing from the pressure sensor. the ecm may be seeing the pressure come up slower and delaying the firing of the injectors compared to what you see. if i recall, the last c7 i had problems with made just under 4000psi at full throttle.
Good vid. Shout out to Chase on the camerawork. Loved the outtakes at the end.
Thanks for posting.
Pretty neat how you remember where everyone is, I just started my channel. I had one yrs ago got away from it, I’ve had my fb up for a long time, I’ll start putting more work related videos up ASAP, I can only go as for as my work let’s me.. really enjoy your channel Kee the videos coming
Good video brother. Surprised that you don't need cables and terminals after that long start ... lol
Nice camera work to your son 👍. Princess Jamie is another one in that group ,plus a couple others I am not familiar with. I know all the ones you mentioned. Thanks Phil for the video's...
Lint burns bro. Good videos! Cheers
Good job Phil.
I am Having the same issue right now.Thanks for the video.
Hopefully it helps
Its in the shop right now.Will know tomorow
Great video! Been a long time since I’ve done injectors on a cat...I am kinda grumpy , I get that from my uncle Dave 😂
A couple questions; 1 how many miles were on the engine, 2 approx how many hours was the O ring job, 3 was the engine using oil by passing oil into the fuel return with the bad oil O ring on the oil side. HEIU pressure looked good once up in the rpm. Looked like it was a Little slow building pressure for starts. As you know if the HEIU pump comes apart the injectors are toast along with oil passages etc. Good vid. Thanks
Thanks for sharing bud ! Happy New Year! 🍻
Awesome video man
Great video.
Great video I loved the outtakes hopefully you didn’t go all Tom Cruise on your crew and start yelling at them lol
Definitely sounds better
Other than a hard start is there other runability issues? Have a c7 in a rv that seems a little weak on hills but i am 32k loaded.
Injection Pressure looked good while running. If you get ahold of Cat ET you can do a step test to check the pump. Top pressure in that test is 3600PSI and you were hitting 3k with no load so I wouldn't be too worried about the pump, but you never know. 1600ish idle is pretty normal. If your worried about the crank time it may be worth trying a thinner oil if your using 15w40. I ran 10w30 cat oil in a F750 with a C7.
Thank you for the information. I’ll try 1030 next time I change the oil. I appreciate the comment👍🏻
The Blooper Reel is Funny! Lol. Good video though.👍
BTW, those injectors dont have a copper oring on the nozzle?
I’m told no the cup seals them in the taper.
Just question
I m going replace the oring on c7 cat 2003. Di we need to release sny fuel or oil bsfire removed injectors and after injectors install what the torque fir them and does it need prine any fuelnor oil before try crank it.
Just to know i get good job ?
👍??
Bolts torquedown ??
Torque for injector bolt??
Love the video
Thank you
Quick question man you ever replaced orings and it still loosing prime
My 2004 C7 in a 2005 f750 seems loud, are these engines kinda louder at idle than when going 20+
What's the torque for hold down bolts??👍
👍
9nm
Or
Nice video I’m wondering where is your shop located at
Terrell I’m located in Michigan
Bad o-ring seal can also cause of fuel delution
If one of those oil seals are no good will it cause the truck not to turn on?
More than likely. It robs hpo from system
What size/thread pitch were those bolts you used to install the unit injectors? Thanks!
8mm-1.25
