N14 Celect tear down.

Cracked Piston or Piston will not account for water in crankcase. Look at head gaskets and liners close.

 

Next time drop the pan and find out where the coolant is coming from.

What condition was the cooling system in? Green or red? Watered down and rusty? Can you test it?

 

Water in the pan could be from a cracked liner but I don’t think there’s much if any chance of that making crankcase pressure. I don’t think the head gasket would let that much through either…it’s pretty much a piece of sheet metal. Did it have lots of pressure in the radiator? Possibly a piston broke which will cause tons of blowby and wedged in the liner and cracked it letting the water in

 

This ^^^^^^ I guess I would of dropped the pan and pressurized the cooling system
There is the chance it has a cracked head after all it is a cumm-a-part

 

Because a CAT would never cracked a head.

 

Lol you said it I didn’t I have nothing against a Cummdumper as long as I never own one

 

Those pistons look like ###
Bearings look surprisingly good for how much junk has probably been floating around in the oil
Did it get hot?? Seems odd to have that many pistons looking that bad. Also thought they had gone to 2 part steel top pistons on all n14s above?370? Hp
I think I remember you saying this on was 460?
Just judging by the soot on the bottom of the heads it looks like it was relatively healthy and I would be pretty certain the water wasn’t coming in above the pistons
