a little more history.- i noticed a small amount of oil seepage at the turbo to exhaust pipe joint apx. 2 1/2 hours into my coolant flush, we have a steep grade hill apx. 1/4 mile long going up to one of our mine pits behind our shop. this is where i was able to load the engine up to 27 psi boost off & on brakes to build a boost psi from 10 to 27 psi. returning to work the next day i started the truck to warm & build air to drive it into the shop, when i was side tracked with an electrical problem from another driver -returning to my eng. rebuild project apx. 1-1/4 hour later (note: eng had been left idling ). removed turbo to r&r water pump & looked at the exhaust ports due to a red flag exhaust joint oil leak to find a little wet around valve stems at # XXXXX cyl port. my exhaust manifold was dry to the touch releaving concerns at this time -after the water pump r&r i started engine with no turbo to charge a/c system due to waiting for a new turbo replacement. at this time my slobber problem came to life (what a drag!). my thought is as yours, give it a good run in under a full 100/500 lb. hwy. load, [state of wa.] if my oil control ring is broken or damaged, do you think i could damage #3 piston set? if my piston skirt breaks away i'm at a big loss. old school pistons, no worries. my run-in time & idle time was twice as long as normal before sending it to work. well this is were i stand, do or die, i'm looking for another professional opinion.

thank you for the advice .have you seen this symptom often & does a good run in normaly stop this slobbering problem.
