- In this video we show how to replace the high pressure fuel injector seals. This is required service whenever the injectors are removed from the heads. We demonstrate the process on my L83 5.3L engine but this guide applies to most modern GM engines such as the 5.3 L83, 6.2 L86, LT1 and LT4 Engines found in the Silverado, GMC Sierra, C7 Corvette, C8 Corvette, Camaro, CTS-V, and more!

I just pulled the injectors from a 2015. I was worried about the umbrellas and didn't understand what happened to the old ones. Thankfully you mentioned that they weren't there to start with!
this is the best and most informative video on this topic please please please like comment and share, Thank You So much for saving me from all of my stuttering truck problems
I found video very helpful. I did however notice they may still be a tad bit loose. I took a heathyn and very lightly waved it over them. Tightened them up more to my satisfaction. Thanks again
Glad it was helpful!
Very helpful for my build. Thanks!
Glad to help! ;)
Thank you!
First time with these, subbed!
I merely used an old ink pen to install a teflon/nylon seal. A "new" set of 3rd party Amazon injectors arrived with a split seal on the double seal part but I already had 'em in the rails before I noticed, and since the seller seemed to take their time to respond (and then only to ask for pics) I twisted the steel body off an old injector and reused the old seal. I placed the seal in a glass of hot water and proceeded to stretch it over the tapered ink pen cap. It got thinner as it enlarged. I had to enlarge it several times to slide over the first seal that was in place but the ink pen body was the tool that made that possible. Then I rolled the seal between my fingers to shrink it enough to fit inside that tapered ink pen cap, which then shrunk and fattened the seal to match the others. So far the seal is holding up.
Great video. Thank you for posting it.
Glad to help!
Thanks for the video, I couldn’t figure out how to get those orings on
Glad to help!
Does the Chevrolet Silverado 1500 LT, year 2011, V8 5.3 liter Vortec engine have direct or indirect injection? Please help me
@ The Sundae Drive, I'm wondering, will any deformation of the seal cause a vacuum issue of any sort?
Did you lubricate the teflon seals on bottom of injectors when you installed back in head
Opinions please! I saw this video series 3 years ago when you released it. Now I am rewatching it again because I'm planning on replacing all 8 injectors soon in my truck. 2017 silverado 113,500 miles. I have one injector that is leaking very slowly at top of engine and I also believe it is causing some occasional bogging of the engine so I'm going to replace all 8. The dealer wants $137 a peice for the injectors. Is it worth it or should I get aftermarket ones??
if I’m replacing the injectors on a 2006 Pontiac Grand Prix GT
all i gotta do is remove the old injectors, and use new injectors?
all i gotta put on the new injectors in upper and lower rings
or do new injectors already have the upper and lower rings on them
and why is the lower ring a different size than the upper ring?
i believe that it’s the lower ring that seems “way too loose” on the injector
and i don’t understand why
those "umbrellas" are to help keep the dirt out which in turn helps keep them from getting stuck
Like and subscribe just for the explanation on the white umbrellas. I looked everywhere to see if I should use those on a '14 model.
@ The Sundae Drive. Ive got another question. Also when you removed the fuel injectors that stayed in the head/block. Was there anything to removed the dirt/debris that stays there. Like a pick or special tool
I just used a vacuum and small pick to clean it as best I could. Because I was swapping the heads tho, I didn't pull the injectors out of this head because I could not get them out. A special tool is required that I didn't have.
If you are swapping heads, I would pull the heads and then just take them to your local dealer and have them pull the injectors if yours were as stuck as mine. On newer low mileage vehicles they will pull out easily with the rail.
2016 silverado I Just had all my injectors replaced now I am getting a gas smell could it be seals not sitting right also would the check engine light go on.
Did you get your issue resolved? I’m having the same problem
Hello did you fix it ? I have the same problem. I smell gas inside of the cab. Car dealer changed the seal of tw injectors. It’s still smell bad
@The Sundae Drive: if the lower gasket are a one use only why not just cut them with a exacto knife to reduce doing damage to the injector with a pick.....
I think the risk is similar. If you slide with the knife you could also score the injector. Personally I felt that the pick tool was the safer option. both will work tho but either way, you need to be careful.
Thanks. I was told it required special tools... but I guess those must be pretty cheap. Good to know. I'm about to do my injectors. Seems like it's really a "not a maintenance" maintenance item. 🙄. What usually fails? Do the seals blow out or do the injectors actually fail internally? What's more common?
I don't think the seals fail super often. Normally it would be an injector failure.
@TheSundaeDrive any experience with good vs cheap (amazon) injectors?
Do you have video on putting fuel rails back in Mumbai Vehicle is a 2017 xt5 Cady
I meant to type my vehicle
I believe during the assembly part of our arm series we do yes.
I notice when you removed the fuel rail, the fuel injectors stayed on the block/head. How did you remove them? What do I have to do to get them out.
It requires a special tool I didn't have. They were extremely corroded into place so I just sent them in with the head core charge 😅 they already had 110K so I figured better to go with new ones. On a lower mileage vehicle they pull out pretty easily with the fuel rail
@@TheSundaeDrive lol alright. Cuz I'm trying to figure a way out how to remove it. It's injector #7 n man r they a pain to remove. That's the only one I need but couldn't figure out how to remove it
You could always take the head do a local dealer or performance shop and have them remove it. Definitely replace all the gaskets.
@@TheSundaeDrive sounds like a plan. Thank you
No problem! Best of luck with it
How come you didn’t just plug in a Range Technology dongle to turn off the V4 mode?? Also, why didn’t you install a billet torque converter when you had the engine out? Direct Injection causes a ton of carbon build up on the valve seats. I hope you use a catch can now too.
I've been running a catch can since 50K miles :) we have installation guide on it up in the channel for it. I talked to circle D and because I wanted to stay close to stock stall for towing, they recommend the 6l90 torque converter. If the trans makes it to 200K I plan to swap the tc again and will look into stronger aftermarket options. Range devices do not prevent the failure. Many documented cases of afm lifters still failing with a plug in tuner.
Hey brother great job thanks for sharing this! Are you in California?
You are welcome! East Coast actually in nj
@@TheSundaeDrive oh wow sad. To bad for us in the west cost. Keep up the good work brother
It's not a one time use. You need a special tool to pull the injectors out. Alldata has the information on that!!
Why didn't you finish and explain how to put them back in
We do in the engine reassembly video
