Ok i bought this truck an it ran good then one day it started knocking really bad so i replaced the crank shaft an bearings. Put everything back together started the truck an it ran like crap an i just happened to check the oil an it is milky. All the water in y radiator is now in the motor oil an truck has no power does anyone have. Any idea what i should do

 

Change the head gaskets. Sounds like you blew the gaskets

 

I think it blew a head gasket too but I didn't drive it that far and when I went to start it the next day Iran like it had a blown head gasket so I check the oil in it was Melky but before i took the motor out it ran.fine justknocked
