Totally Dissapointed!!!!!
Hopefully something simple. I had a intake gasket go out of the 454 in my tool truck and it sucked oil like a big dog. It went from a quart a thousand to
a quart every hundred. I didn't notice much smoke, it aparently used it at highway speeds when the oil is splashing around more with rpm. If carb/tune-up/etc are all ok and nothing you've done has made any difference I would pull the intake and see what the gaskets look like. then pull the engine if you have to. You'll have to keep us posted. toolmanmike
