Update: I keep seeing guys skip the torque sequence on Duramax head gaskets

Back when I was at the shop in Boise, we had a binder with the exact 7-step sequence for the LBZ, and it was GOSPEL. Now I watch videos where people just crank them down in a circle and it drives me nuts. That uneven clamp is why you get that weep at the rear after 20k miles. Anyone else still using the factory service manual for this, or is everyone just winging it now?

My own head gasket is the weepy one after I tried to wing it.

Winging it is a sure way to get a leak. Those bolts need the right torque in the right order. It's a lesson you only learn once.
