There is an upper and a lower, they separate fine.Wouldn’t the tabs be worn off on the bearing if they spun? That first picture of #5 I’m trying to decipher. Do you have an upper and lower bearing for that one or is that one melted into the other.
Yes, fresh build of everything. New oil, filter, fluid. Only oil. But after a few hours of crank no start, then it ran for 4 seconds. So, when it started, there was likely already a large amount of antifreeze in the oil.So you started the "crank no start" session with fresh oil in the crankcase?
I cleaned the top of the pistons with simple green several times, then cleaned with brake cleaner, then wiped nicely. They all looked nice when I put the cylinder head back on.When you originally replaced the head gasket how did you clean the tops of the pistons? Any chemicals used may have washed away any protective lubrication as all the cylinder walls look dry, scuffed with corrosion beyond what would have occurred after the engine locked up.
No issues on the vehicle at all when I decided to do HG as PM.Did you have any previous high temp issues?
I hadn't noticed that, good find. That very well could have been the issue. It looks as if that clamp may have interfered with the correct seating of the head. Wow, this is interesting for sure. It would have caused a sizable gap there. Wow! Thinking...It looks as if the PHH clamp caused interference between the block and head. You can see the indentation from it once you took the head off.
I’ve noted this interference when installing the head and how it did not seat perfectly flush. The PHH clamp needs to be installed with this in mind. This could have caused coolant to enter the system.
Good catch on that! That's the voice of experience!It looks as if the PHH clamp caused interference between the block and head. You can see the indentation from it once you took the head off.

Great observation. Definitely looks like the constant clamp indention on HG. Might just be from positioning and lowering head onto motor. It looks from pic that clamp is in the clear? I would think a rectangle imprint from clamp on HG would be present about an inch long if it didn't seat flush? Is the rear of the phh nipple flush with motor block when mounted?
