Havent Seen Much About Valve Adjustment, I Had To Replace Injectors In My 02 Gmc, While I Had It Tore Down I Decided To Ck The Clerance On My Valves, To My Suprise Some Were Up To 28", I Set Them Back To Factory Specs, It Is So Much Quiter, So If You Have To Have Injectors Have Your Valves Adjusted, It's No Problem While Valve Covers Are Off.

how many miles were on it? usually they say 130k before any type of adjustment is recomended. but it dosent hurt to check...

it funny you bring this up there was a post not long ago that the dealer tried to get customer to adj valves while apart and he felt like he was getting screwed.

fricken dealers....always trying to keep the working man down buy constantly ripping him off...lol....

There is no published gm service interval for valve adjustment that i know of...

.012" is stock lash...


you can run down .010

Anyone know if the LMM's have manual lash adjustment?

:when i took mine in i asked the stealer personally to check my valve lash on my 02 dmax and he said that it was not necessary that he saw a lot of oilfield trucks 200k+ that were still right on......so he didn't check them:damnit1::wtf1:

All d-maxes have provsions for valve adjustment. This is the first place i have heard of adjusting the valves on a dmax for no reason other than being in the area during a injector replacement, it is not a required service as per g.m.
