setting valve lash

[dirttymaxx]

im not sure if this is where this should go,so move if needed

setting lash on a lly/lbz i have a tick on the driver side of the engine,i wanna know if anyone has done it with just removing the upper valve cover?? plz plz dont tell me i have to take the lower cover off to! because that means injectors has to come out!

intake .013
exhaust .013

You can do it but it will help to have a set of angled feeler gauges. Also the valve lash is .012

 

[dirttymaxx]

socal told me .014 so i went with .013 for a little more bottom end,so im to lose all around then great! o well

I set mine at .011

 

[juddski88]

I was told .010 by Tony B when i set mine...but my motor aint stock

 

[dirttymaxx]

sounds like im lose tighter it is then! shoothing for .011 now

I went with .010 on the intake side and .012 on the exhaust side.

I went with .010 on the intake side and .012 on the exhaust side.

Any particular reason for that?? Just curious...

 

[S Phinney]

Typically exhaust side items run warmer than intake side items. I felt it might help make them a little more equal. Also one of the big time engine builders also recommended it too.

A little more bottom end? All setting them loose is gonna do is make it louder.

Personally I set them at .010-.011". Factory spec is .012"

 

[dirttymaxx]

like i stated i was told factory was 0.14,from a rep out in ca. should of dubble checked it,but i didnt,next time i will!!!!!!!!!!

Id be curious who told you .014". Every service document and engineering paper ever written on the duramax says .012" for both the intake and exhaust.

well i think it was a mistake,so im not going to name names or anything.
