The number 5&6 run hot. Its because of the pump and those two being at the back of the block. Cummins made the factory bypass for a reason. They know it will blow the rear plug and run hot. The electric pump belongs off road... Hope this helps..

I am pretty sure that water outlet was only used when they had air compressors.

How about putting an air conditioner clutch on the water pump that slips at higher RPM's...

Yes IT will blow, regaurdless of rust or not..Too much thinking bro.. head stud it if its leaking in the front. The plug that blows out is the one in the back of the block.

Will studs fix the problem? That front corner of the head is kinda far away from a bolt/stud. I was thinking the head warps under pressure and that's when it starts leaking.

Yea, I know I'm probably overthinking it, but that's cheaper!
