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

Not sure if you guys are into 3d printing. I just started playing with cad and 3d printing. I want to get into making some on the cnc but I want to design and program the stuff myself so I can make changes on the fly. Both of these I had all the help with lol. But I am learning

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…

The top end was rebuilt new spring rockers and valves stock push rods new oil pump. I have to set valve lash and prime the oil system. What is the best way to ensure oil is were it needs to be. Tips and tricks to prime the oil. Also is there a way to test the oil cooler or am I better off buying a new one.

Well this engine belongs to @Claude Lafond This right here is the part of the reason I show people and want to help. No need for this to happen to a guy. But fear not we will get him fixed up https://youtu.be/c0G9Ey0O4eU?si=tnMbBoB6cOWWlUOf
