8050 pushing coolant

cjrpr · Mar 7, 2015

I have a 8050 was pretty low on coolant. I filled it up and ran it and it pushes coolant with bubbles out the filler cap like crazy with the cap off. also smokes white and runs rough for the first few minutes. what do you guys think is going on? cracked head or head gasket or hole in a liner? what is the best was to find the problem? thanks for any help.

I would bet on the head gasket. Cracked head? possibly, but not likely unless it ran for a time with no coolant. Hole in liner? Doubtful. That more likely will just put water in the oil. Most liner holes occur too far down to allow much compression into the water jacket.

When replacing the head gasket, be sure to run a tap down each head bolt hole in the block and blow them clean. Clean off all head bolts and replace as needed for pitting/damage. I always use a little grease on the threads when assembling and torque to 150 ft lbs. Run for a couple hrs at wide open throttle and let cool down overnight. Retorque when COLD to 165 ft lbs and set tappets to .017" COLD. Check injection pump timing to be no more than 19 degrees BTDC.
