2250 Oil in Coolant.

[5cylinder]

The new cooler was the updated cooler with updated gasket set. The reason I tore the engine down was if the cooling system pressurized wasn't loosing pressure or coolant, Then dropping the pan isnt going to show its self so I wanted to test the head. When the machine shop said the head was good, I wanted to visually inspect the liner o-rings. I'm not trying to dispute, just trying to educate myself for the future. The last thing I would want to do is to waste customer money.
