@Wild one was putting head back on and one of the small bolts broke. It was next to last bolt to torque down. I am going to have to take head back off to get broken bolt out of the block. Is there any problem with using the head gasket I just put on? Since I torqued all the bolts to spec, I need to start over with fresh bolts?? It a set felpro head bolts.

I'd reuse it if it hasn't been heat cycled. I've never used Felpro's Hemi head bolts,but now i think i'll stick with either OEM or ARP's head bolts if you broke one

@Wild one finally getting truck back together.
I drained the heater core hoses and this milky looking antifreeze came out of it.
What could this be? I don't remember any of the other antifreeze looking this.
Thanks

That's a new colour to me to,lol.Are you flushing the heater core with something that might change the colour of the antifreeze in the heater core

No flush. Just unhooked hoses on front side and drained them.

It looks like someone in the trucks past mixed some Mopar purple OAT coolant with something lighter colored, like Dexcool or G05.

Given that it is still pretty purple, my guess is that it was low, or maybe after a water pump replacement, someone topped up with some parts store "Universal" type coolant.

I doubt it is anything to worry about. It's a good reason and opportunity to flush and refill.

I did buy the truck used. That could very well be possible. Thanks

Mopar coolant is either pink or purple depending on temperature. I think this was first year of casting sand issue, and it appears you have some. Save that bag there may be a class action on it.

I'd run some RMI 25 for a run and check overflow, and stay with Mopar coolant as you still have good color, meaning it will mix well.

Gents. Got truck back together and running. I have a couple of things that I do not understand. I got OBD J, it's giving U1424 code. See pictures. My basic OBDII doesn't show the U1424 code. Also attached are all the live measurements. There's a little rough (kinda vibration or shaking). Thermostat code is because I don't have the Thermostat in right now. Anyone see anything concerning in the data?
I see misfires on 2,4, and 6. It's one on each? Is that a concern? I appreciate the input.

U1424 means Implausible Torque signal. Usually This is set by the transmission control module when the truck goes into limp mode.

Unless I am mistaken.

I was towing once from AZ to WA state and had this code set while passing through Idaho, when my transmission went into limp mode. It turned out that the transmission got too hot on a 105+ degree day, pulling 7500 lbs too fast up a long mountain grade. It hit it's max threshold and went into limp mode. I dropped it at a dealer in Boise overnight and got a hotel room.

They couldn't find anything wrong with it other than U1424 code. The said that the code "probably" was set by the TCM when it went into limp mode, so they flushed the transmission fluid, and I finished the trip without incident. I had the truck for another 3 years with no trouble, before I traded it for my current ride.

Did you do anything with the transmission?

Nothing to the transmission. We well see what happens.
