Finally a video we’re you set them #4 tdc first, that’s how I did mine but only seen videos of guys doing it #1 tdc first. I was told a little tighter drag helps with higher rpm trucks
@@screamindieselltd what is the service intervals on valve lash adjustment? I'm familiar with semi trucks seeing the overhead every 120,000. How often should this be done on an LMM? Thanks
replaced a head gasket on my lb7, considering all of the rockers come of as one i found it unnecessary to set valve lash. 1 pushrod later i know have changed that opinion. thank you for the video sir
I just rebuilt my 06 LBZ and I did the adjustment while the engine was on the stand but I think I may have gone a little tighter than how he explained it. I do have a little bit of a tick that I can hear but I'm not sure if it's exhaust or the valve lash
If you're in there for injectors, it's much easier to turn the motor over when they're out. I didn't have to bother with the balancer, just stuck a 23mm socket on the alternator and turned it over
Is it common to have to adjust these at 200,000? My truck has a slight ticking coming from the passenger side and it’s in tune with the rpm’s… my injectors are fine no white smoke or anything.
@@screamindieselltd thanks for replying man. Been trying to figure out this tick for a couple months I think I’ve finally narrowed it down to valve lash or an injector.
As for gaskets to do this.... A VC kit that includes upper, lower, bolt seals, and injector seats.. plus t-stat orings. Is this all thats needed? Or is their a gasket for the filter housing?
lots lol! injectors, injection lines, electrical harness for engine, charge pipes, upper valve covers and lower valve covers, upper rad hose coolant pipe, glow plug control module, high pressure rails, FICM, fuel filter housing. i believe the front brackets that hold the alternator and A/C compressor as well. I had the heads off for head gaskets so there is more off in the valley than there needs to be to get to the valves, but that's roughly what would need to come off. Thanks for the Question and have a good one!!
Great video. Could my LB7 be in need of a valve adjustment? Currently smoking under load or acceleration. Injector balance rates are well within spec. Stock LB7 w/ 1.3 million miles. Valves were last done w/ head gaskets at 520k. No leaks in turbo system. I'm planning to do this valve lash adjustment, regardless.
Valves being out don’t usually cause smoke under load and acceleration. That’s usually a turbo, plugged air filter, plugged fuel filter or injectors. Is there any smoke at idle? When you checked balance rates did you compensate for fuel rate? MM3?
@@screamindieselltd I have this issue on my lb7. Smoke on acceleration but not at idle. Injectors done 1 year and a half ago with Napa injectors. I checked air filter and not sure what’s causing smoke when accelerating. Not even a haze on a very cold day from exhaust.
I know in the heavy duty industry if a ticking is heard it’s most like in need of a valve set but my lb7 is make the same ticking noise what are the odds of it needing a valve set. All injectors are good.
@@screamindieselltd would you take it back apart just for that? She running great and more quiet then she’s ever been I know I got everything aligned very well with my eye? Can the assembly move after it’s been torqued without those dowel pins?
I'm getting just under 100psi in cylinder #4 on my 06 LBZ, but my mechanic believes it's a cracked piston. I run a BullyDog tuner and never go over 24lbs of boost and rarely ever get it that high, so I wonder why the cylinder cracked when do not push this truck, and it's only got 120k miles. Perhaps just a bad luck defective piston, but are there any other causes for sudden low compression and knocking? Thanks!
Cracked piston, bent rod, rod bearing, wrist pin bushing would all cause a knock. Bent valves or pushrod you would get a “pop” out the intake or exhaust. That’s about all the at would cause low compression.
Hands down the best explanation of how to set the lash, I just used it while installing new Wagler pushrods during an injector install. Great job!
Thanks! And nice on the waglers 👌
Thank you for a great video. Simple and precise. Doing LB7 injectors today. I checked lash on one cylinder. Measured out to .020 they need adjusted.
Finally a video we’re you set them #4 tdc first, that’s how I did mine but only seen videos of guys doing it #1 tdc first. I was told a little tighter drag helps with higher rpm trucks
Thank you so much ! This video helped me a ton !!!
Appreciate the video, going to be doing injectors on my ‘02 duramax soon so figured I might as well check the lash while in there.
Anytime thanks for the comment!

No problem hoping to have more instructional videos to come! thanks for the comment and it sucks to hear you have to pull it apart again!!

Am going to need the video very soon thanks brother 👍🏼
Not a problem thanks for watching!

That’s for sure. A diesel with no compression is super easy to turn over.
Straight forward, great video brother!
Thanks for watching!

Yeah it is possible. They are not hydraulic lifters and so if the gap gets wider then you have to adjusted it manually
@@screamindieselltd thanks for replying man. Been trying to figure out this tick for a couple months I think I’ve finally narrowed it down to valve lash or an injector.
@@screamindieselltd also have you ever set them to 0.11”? Any benefits over 12 thousandths
Great video. Thanks for sharing.

Yup that’s pretty much all that’s needed. The gaskets for the filter housing are in the housing so you don’t take them apart at all.
@@screamindieselltd Great, thank you!
Great video! Helps lots
Thanks! Glad to help
Thanks alot for sharing very usefull.
No problem glad to help.
quick question, what is all removed to access the both valve covers this open?
lots lol! injectors, injection lines, electrical harness for engine, charge pipes, upper valve covers and lower valve covers, upper rad hose coolant pipe, glow plug control module, high pressure rails, FICM, fuel filter housing. i believe the front brackets that hold the alternator and A/C compressor as well.

Its definitely a possibility that they need to be set.
I forgot those 2 dowels for the rocker shaft I’ve probably put about 500 miles on since then.. how important are those
They just line everything up you may get some funny wear in the bridges and arms over time

What are the symptoms of valves being out of spec?
Great video
Thanks! Glad you liked it
My friend I want to ask you, wy is my duramax in smoking alot by the exsos ,or in espanich mofle
What year duramax? If it’s an LB7 (01-early 04) then most likely it needs injectors. Thanks for the comment!
Call me dumb but was definitely using u as a Manuel but u didn’t say the other valves on second half
Full procedure is in the video description
Is there any torque specs. On the adjustment nut.?
16 ftlbs
Will this work on a 2015 LML?
I believe it will but I found conflicting info on the lml so I used the years I know for sure it will work on.
@@screamindieselltd thank you for the reply back! Great video!!
@@allenscherer589 anytime!
I'm sorry did you say "Zed"‽
Lol its the Canadian coming out 😂
