'''A good shop will diagnose the problem before just yanking the heads. Proper way to check it would be to remove the oil pan and pressurize the cooling system and look for coolant on the floor. When it appears they will look up into the engine to see where it's coming from. Usually if it's leaking back through the oil pump pick up it will be the oil cooler if it's coming from a cylinder and leaking down the inside of the liner they will pull that injector and look to see if there is an apparent drip into the cylinder which would be possible injector sleeve or cracked head. Then it comes apart and head is pressure tested or oil cooler. Could also be a cracked liner. Good Luck.'''''italic text''
