On Top Of Ol’ Smokey

1970 Challenger, 440. I am having
problems with burning oil at startup and on
a steeper downhill slope, a cloud of blue
smoke, It goes away when accelerating or
just normal running. What does this sound
like to you?

Valve stem seals brittle or very worn
valve guides are usually the cause of
startup smoke. The downhill deal aspect
isn’t as easy to diagnose. I’m thinking oil
overfilled, PCV pullover (poorly baffled
aftermarket valve covers), or….?
Anyway, fix it soon, or it’ll be a
carboned-up mess.
