RE: Crankcase pressure
Figure I would give an update.

Got a platitum kit from cat and it came with a new head, evidently they were out of remans. They said sometimes that happens.

Head is getting checked out now.

Took my crank to a different machine shop and they cleaned up thrust area. They do all of the local cat shops work, Said it wasn't as bad as it looked. And then they polished it. So it's still std.

Liner protrusion was almost the same on every cyl., they read right at .0049 inches which is in spec. Cat said sometimes they are all similar. I just thought it was weird. I followed the sis instructions, torqued liner down, measured in 4 spots. Each cyl. Used an actual liner protrusion gauge.

The crankshaft endplay was .010 inches which is right in spec too.

The kit didn't come with cam bearings but I bought cat cam bearings and put them in and before that I took out oil galley plugs and cleaned everything out.

Bought separately a rear and front structure kit on top of the rebuild kit. Came with new bolts etc.

I still need to get a cam and a turbo. My cam is junk, a cpl intake lobes have pits in them.

I cleaned all the parts, and repainted every thing that bolts on motor. I was to get the valve covers chrome dipped but I don't know if that's worth $750 lol don't make it run better.

I've been using the sis program to put motor together. It's super handy. I follow it step by step.

Everything on motor in and on it is getting replaced with stock stuff. No high performance crap. The only part I'm not replacing is the ecm as it's 3 years old.

While motor is out I changed the input shaft and bearing in trans and all the linkage. Also bought a new clutch.

Anyways, It's taken awhile as I have other trucks and disasters. My favorite truck which is a international with a ism had the fan hub studs break off of the head, I tried everything to get broken studs out, even had cummins come out. They couldn't get so I torched the bitches out and cleaned up the threads. And locktited new studs in head. Was a giant nightmare, but worked good.

And I had a clutch go out. So haven't had much time to focus on this show motor I'm working on. But it's getting there.

Going to be the most bad ass 435hp c12 around here lol
