Cat d8h question

I’m helping a buddy of mine pull a d342 out of his d8 due to broken crankshaft. Does anyone have any idea what the weight of engine and clutch housing could be with both heads and fan hub removed. Trying to figure out if my 6006i imt crane will be enough to pick it. It would be a pain in the ass to get a bigger piece of equipment to where it is sitting at.
Thanks

1lw 3406e head gasket issue

Customer said he was loosing coolant after hard pull. Found evidence of coolant out overflow. Put the bubbler and a pressure gauge on and verified it would build 15 psi in cooling system then start pushing coolant while pulling a hill. Customer already replaced air compressor with no change. Pulled cylinder head. Couldn’t find any issues with head gasket. Did find a lot of rust built up on the liner flange, spacer plate and the head bolts for number 5 cylinder. Also found 2 cracks in the head between the valves on cyl 5. Had machine shop pressure test head and they said it passed. Liner protrusion is between .004 and .005 all the way around. Is it possible that head gasket is leaking and we just can’t see it. This engine also only has 70000 miles since last inframe

2017 international pro star can bus issues

Got one that’s stumping me. Pro star with x15 and Eaton autoshift. Truck is intermittently stalling out, losing all gauges and and shifter starts flashing while going down the road. Found a ton of communication codes across almost every module, all inactive when it came in. Checked batteries, all ground connections, pulled apart most connectors to look for corrosion and visually inspected harnesses looking for rub spots. No issues there. Happened to hop in the truck and noticed the gauges flickered, if I stand on the step and shake the cab I can get it to act up but will start working again right when you stop. Found out when it’s acting up voltage on can hi and can low both drop to zero volts at the same time. Unplugged cab harnesses to narrow down whether it was in the cab or not. Did not act up with cab disconnected. Hooked everything back up and now it runs just fine. Any ideas where to go from here. Hate to send it out and have it come right back
