Ah, memories. Did my 03, CA LB7 (w/EGR) last summer...over many more days than I care to admit 😀. Had to smile when your guy lifted off the upper valve cover. As you know, many folks struggle mightily at that point and I found a large block of wood and a 5# hammer popped both sides off easily (strike down from the valley side). I also appreciate your insight on not trusting balance rates alone as a diagnostic tool. That Tech 2 check of injector on time told the whole story. Looks like you did a lot of work to isolate return lines from each bank for a return flow test. A trick I learned is to break into the main return line just ahead of the tank and check there. You will obviously not get bank-by-bank but the total should tell you what you need to know. I doubt you would ever recommend injector R&R on ones bank anyway. Another important point is in regard to those pesky, shallow head hex fasteners under the covers. Mine all came out fairly easily (also the many other hex on this job) because I was careful to deeply seat my tool into each upon removal. I bought new, deeper hex for under the VC's. On valve adjustment, think I may have gone a bit tighter than you did (10 thou?) which quieted the engine dramatically. I was amazed that clearances were all over the map (high). I snugged up the serp tensioner with a blocked breaker bar and used the alternator nut to turn the engine. As I rookie, I bagged and tagged all my bits and wrote a step-by-step log of everything I did, then went through in reverse when putting things back. Only a few leftover items (which didn't look too important 😀) and the beast fired on the third series of cranks and has been excellent for 2500 miles with no leaks. So, on that injector job I'm guessing what, 4-6 large? Best.

I’ll tell you what you guys look like real professional your shop is clean your fluid in your video too bad you’re not closer to me in my town I got LB7

Wow i was very impressed with the information provided and the quality of this video. Explained many things with great detail and it wasn't 2 whole minutes of umm and uhh. He had it down all the way through straight to the point.

LB7 Life baby!! You guys are the best.

Thank you for the LB7 content! I'm gearing up to do the injectors on mine this Spring 😀🤘

That upper valve cover sure came off easy 😀. Instead of prying, I used a block of wood and a mallet to pop mine loose. Only one cup came out and I cleaned everything and reinstalled. Also, is Bosch even making “new” injectors. I contend all LB7 injectors are remans of the improved (better bodies and return seats) units. And hey, it says right on the FICM “don’t power wash”. Otherwise, excellent video 👍👍👍.

Great video guys. You should do more of these .

Awesome videos guys, thankfully I bought the warranty for injectors!

Very clear information professionally done.

Thank you so much!!!!!!

Damn great video..I am sick 17k.2 years miles truck starting to smoke and the shop ..will not call me back

What can I expect to pay a reputable shop to do this?

Do they make SAC 45 over microphones?

I've got two questions. What did you put on the copper crush washers to keep them in place right before installing them? Second is could you give the specifics of installing the cups? what type of Loktite and where the loktite goes thank you for any input you could give,

My 03 is smoking, however my command rates are high. Stay Around .50 could this still be injectors?

I ordered a head gasket and fuel injector kit (I didn’t order them from you, i didn’t know. I think it was Lincoln)and it came with five little tubes of loctite, im not sure what it’s for, I’ve got my heads back on and installed the injectors today, are you supposed to put loctite on the banjo washers on the fuel return lines that screw on the injectors (LB7). Thanks for any advice.

Why was his coolant tank so dirty....leak in head gasket or egr cooler????

I was getting antifreeze in my oil and everyone said it was a blown head gasket, I got the heads off today finally and there’s no sign of them leaking anywhere, where else might my problem be? Please please, any advice in appreciated.

Hey that intake heater controller module near the fire wall on the gmc I'm trying to figure out where the ground white goes too i hooked all three wires right but I out have a black wire left which is the 4th black wire I forgot where it bolts too it's an 2003 gmc 6.6 diesel 2500 I did the injectors

What if you ignore the haze, and it starts knocking and smoking really bad. I didn't know my injectors were bad. Is the knock possibly a washed out cylinder that now has a loose piston ?

Hello what happens if I connect an injector the wrong way?

I have a 2001 lb7 101000 miles no smoke no miss starts easy cold n hot runs like new. But I'm getting crank case filled with fuel. Is that injector body cracked?

I have an LB7 that smokes at idle and my Balancing rate are averaging out to -2.62 but only my number 5 cylinder is reading +15 could this be an injector harness I have replaced all injectors but the #5 is the only one that has not changed has stayed the same??

My high pressure fuel injector line failed and is leaking. Im going to replace it. My question is.... what is the torque on these lines or are they just snug tight? Also, do I have to bleed they system after replacing the line? If so, how is that done?

hello, Could you help me with a P02146 code that goes in the limp mode. we apreciate any help, thank you.

Where are you guys located?

Helo guys I have a 04 kodiak whit the lb7 I have no fuel on the return line and no fuel in fuel rail

My truck is hazing pretty bad now only thing I can see is balance rates and I only have one out of spec at -5.9 the rest are under 2 . It starting to smoke bad can I get away with replacing that one since it’s in the easy side of the passenger side or what sir 😊
