Detroit Series 60 white smoke at cold start

It’s a common problem, as you now know. I doubt it will hurt anything. Detroit knows about it, but pretends they don’t. They even had a settlement with the epa to fix a certain amount of them, after it became a problem. It’s from the Lo nox programming

 

I run a 12.7 60 series and it does the same thing. I've had it start and it will have a cloud over the lot. It clears up and stops smoking. Probably around 250k on the overhaul and it did this since it was rebuilt. (Not sure if before that because I got the truck in the summer and it conveniently needed overhauled 2 months later.) Keep us posted.

 

I don’t know for sure, but you may get away with changing pistons only. If You have floating wrist pin rods. If You have the bolted type, you may need rods also. I may be wrong, but I think the 16.5:1 pistons all are floating wrist pin design. Ive heard on here, that rods with a drilled oil passageway are available for 12.7s. That would be a nice upgrade, if buying rods anyways. You may be able to use your cam, injectors and Jakes. Injectors and Jakes are matched depending on injector height. Cam is preference. That’s what I’ve read anyways. There’s others on here, that know the numbers real well, and what will work.Just my thoughts.Pistons only can be bought, no need to get whole kit.

My Bk has 7650 injectors.and I forget the jakes, anyway yours are the same.660 maybe. Rods on mine aren’t drilled either. I just recently learned of some being drilled. The jakes match injectors, I’m pretty sure based on height of injector settings, in both our cases, .81. Mahle sells the pistons, all you may need are different rings, some may have a square cut, and some a chamfered edge, something like that maybe.
