Hey Scott.
The head was pressure tested for cracks. came back clear. When unit is under load using hydraulics. smoke is drastically less; I assume it's because revs are down to a minimum. I've driven the unit for about a hour. Mabe i should drive it a bit longer. I had another master technician over for 2nd opinion. however, he thinks that problem is a oil issue. Mabe a oil port is cracked....
My thought is to try a thicker oil. Mabe 20w60 seeing its has over 12000hrs.. before i attempt to strip engine again.
