Early LB7's/Headgaskets?

[blownaway]

Is there really any difference in the 01 LB7's? I have heard to stay away from the 01's but could not find much info on here to support that. I think the headgaskets were different but don't know what trucks to stay away from for sure. I know about LB7 injectors....

i cant say about the later years but my 01 has been a great truck and i've beat the hell out of it , i have hit 45 psi boost without headgasket problems yet knock on wood maybe other will chime in on later years and if gaskets were redesigned .

Mine is an 02' but door says manufactured in 01'. Not sure how exactly you would classify the year model. In any event, I see 40 lbs all day and no gasket issues. Injectors did fail at 100k, 128k now.

Head gaskets are the same on all years now Gm has changed them over the years but a,d,or c grade works on all years.injectors is the big thing on the older trucks.

Thanks guys, It is great to get the unbiased info straight from here.

If you didn't read one of my first posts I was a Cummins guy:villagers:
I got rid of the truck 3 years ago for the Liberty and now I am dying to get back into a diesel truck. My wife and I really like the Chevy/GMC trucks and She especially loves how quite the Duramax is. Her quote was " You did the dodge thing already, lets get a Duramax" :hug: She always hated the Dodges but I wanted the Cummins.....

Are you saying 01's don't have EGR's or something?

[blownaway]

Just 01's?....

 

[jonathancasey19]

Mine says 02' and no egr, cats ect...

 

[dieselson]

Yes

 

[2500HeavyDuty]

any 01 is like that, theres some later models that have no egr on them either, but they are federal emmisions dmaxes. i forget which year where you can only find them with egr and cats

 

[dieselson]

Well I believe 02-04 federal might not have egrs but idk about cats
