I think if it ever comes time to get a short block built I'm gonna look into swamps diesel. Very reasonable prices from what I've seen and their warranty is pretty jam up by the sound of it.

[QUOTE=J83;12218517]

The Duramax engine is an exceptional engine, but it is also far from perfect. There are plenty of issues with it from the beginning of the series, most have been corrected by this point but the crank issue as far as i am aware has never been addressed by GM. It is not a huge issue, as failures are rare, but there is still a clear history of failures going back to the 01 trucks..



[QUOTE=SilverGorillaLML;12218567]Agreed!!
From 01 to 16 these trucks break cranks on, stock or 2000hp, babied or abused, low mileage or high. Doesnt matter. Hit or miss. Unfortunately the af cams have proven not to be the fix all eveyone thought they'd be. Plenty of guys have broken cranks with those also.


Comprendo? Now, go away.

Got my engine but they didn't install the crankshaft gear, the one that drives the cam. They are shipping me one out ASAP, what the best way to install this? Should I bake the gear to 400 degrees for 30min so it slides on easier? Any help or suggestions would be appreciated.

Baking the timing gear will work fine. I installed mine on the crank before it was in the block, and put the crank in the freezer for a while as well. Should slide right on for you.

M.A.M. so I'm following ALLDATAdiy.com for the rebuild procedure and I'm worried about installing the cam wrong. The website just says to line up the timing marks on the crankshaft gear and camshaft gear. Can it be that easy?
