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?

All factory valve covers have PCV
baffles. That’s not always true with
aftermarket covers. If missing,
PCV pullover (high oil consumption,
smoke, knocking, carbon) will result.

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.
