So long story short(well semi short). I bought my truck way back in August now previous owner did a head gasket roughly forty Thousand kms before I bought the truck and with in 24 hours of owing I blew the gasket so after a couple months of denial, I replaced it in December took my head to a machine shop local and they said it was blown on 4-5 5-6 steam port and they took some off, they didn't specify. I put it all together with a oe Cummins gasket and after 3 weeks of driving it under boost and high rpm I head gasket chatter and coolant blowing everywhere. The block was straight when I had the head off. What's my best option ie just replace the gasket, replace the head with a known good one. I'm leaning towards just replacing the head but want your guys opinion. And yes the truck is tune and deleted and it has a mini max v1 and the truck has 411,000k on it

New valves, new seats, new springs… It is so nice and shiny. Initially, I was planning on taking a Dremel to do some polishing to the intake runners. I was also thinking of lapping the valves as well. But maybe fuck all that and just leave well enough alone…

Making a video series for my 6.7 swap. This is just an introduction of my specific build.

This is a video covering the procedure I am using to gap piston rings. I cover what is done for the top ring on a 6.7 Cummins, bored over by 0.020.” Specs are 0.018-0.022” for top ring. Thanks, SW

Not the marks you like too see when doing a head gasket. Still feels smooth. Leaning towards broken ring?# 5 is the whole stoke. You can see #4 but haven’t rotated it
