2016 USED COLUMBIA GLIDER WITH S 60 SERIES

Truck is running good, getting good mpg, i replaced the ecm because it was giving me stop engine light due to low oil pressure ( everything else was checked) Freightliner charged me $2200 with programming included

 

I checked the gauge, oil press sensor, oil ps harness and then used ecm. All done by local shop, at the end it turned out it's the ecm. I did go with Freightliner for the part only not the diagnostics. I'm done doing diagnostics with freightliner

 

It's me again. I'm having a white smoke issue in the morning, sometimes it goes away after 5 10 min, but when extremely cold it would stay all day. Went to shop, they were thinking injector #4 & #6( skow response) . We did replace them, still the same. They are saying a liner, I'm like NO. They said gloss in manifold, and yes i see it in top of pipe, wet glossy. I might be losing less then 1 gallon of coolant every 10000 miles ( i would have to confirm this tomorrow morning). Before all of this happened i had o rings leaking oil in manifold. Bought new cylinder head set from Detroit ( injector cups included) for almost 2k. O rings fixed, no more oil in manifold. I think its crazy to push for overhaul on 542k miles and truck running good just a slow start when really cold. I'm not a mechanic, I'm still learning my way around this truck but this doesn't make any sense. Maybe I'm wrong

I appreciate your feedback, i will do oil samples this week. What do you think about them saying dropped linner just from taking the manifold out? I have less then 11.000 miles on the new head
