Best Duramax manual

[Philv]

Ok next weekend I'm doing injectors and a bunch of other work to my truck. Who makes the best detailed repair manual? I need correct torque specs and I also want to relash the valves.

good luck with the injectors!!! hopefully they all come out with out to much hassle. I have done two sets in my truck and several others and theres a few tricks to doing them efficiently. for the valve cover allen head bolts I would buy new ones as they normally strip out, and the bolts near the firewall are a pain. new return line banjo bolts are a must. Its no small feat if your not prepared. I am sure there is a full guide on here. use the search or go to the lb7 area on here located in hard parts.:thumb:

And to answer your question I don't know which is the best... all I have is the basic book from vato zone that I rarely use. Most of the torq specs can be found on the internet. or just go to socal diesels site for them.

I bought the master kit from LDS. I still need to buy the cup puller and the correct wire wheel to clean the cup bores.

I just use a plumbers 3/4 " wire brush for that. The kind you use to clean copper fittings. Are you just making the cup puller out of a masonry 3/4" sleeved anchor ? It works like a charm!!

Alot easier to navigate than the big gm manuals. I dont even use mine anymore.

Either buy GM manuals or a subscription to AlldataDIY.

There are multiple DIYs out there if you'd just take the time to google for them.

Thanks. That'll help on the injectors. I don't normally trust diy write-ups cause you never know where they got the torque specs. Now I just need to find one for valve lash.

If only you'd look around first....

Ok I found a good download for lash. One thing I don't get is it's saying .012" for all valves. On all diesels I've done, exhaust is different than intake.

Its all the same of the Duramax

 

[THEFERMANATOR]

Fyi, socal diesel has most all of this info on there sight as well.

If you need something specific one of us can always print a procedure from GM's SI. Fred

I don't trust most diy threads in any forum. It's bit me in the ass before. There's been several times I could go on to different threads and get different torque specs from each. That's why I asked about a manual cause they have to put in there what the OEM has in theirs. This is a big job and I have to make sure it's done right cause I can't afford a ****ed up torque speec and break something.

Again. SoCal diesel has almost every spec listed for these trucks.
