Rings for KB pistons 4.080

Oil smoke under deceleration sure says intake (or something connected to the intake tract). With that #3 plug oiled, that symptom sure ought to help zero in on it. Still could be a valve stem or seal.... you can't rule out a mistake in the head work until it is checked for sure. Is the #3 plug still oiled after the intake R&R?

With a ring oiling, you'll typically see that all the time cruising or under power of any level. FWIW, the 2nd ring does appear to have an 'up' direction per the FM site.

I'll be pulling the intake yet again to inspect the gaskets and intake galleys. That damn left side smoke still has me puzzled. The #3 plug was wet prior to intake mill work and after reinstall. She smokes at idle as well as down the road. I had someone following in a second vehicle and they have noticed smoke during cruising and during slowdown. But just out the left pipe.
