Going about 75 on a highway, had a power reduction, and now has a nice stumble and smokes some oil.

F*ck. Time to take it in for some help.

just leave it on the side of the road with a "free to any board member" sign in the window. I'm sure one of us northerners would take care of it. within a day you would have at least a dozen trailer show up. LOL

did it make any noises? (bad juju)
possibly a valve seal oil fouled a plug or 2?

pull the oil pan and vavle covers off and see if u can see anything

I'd look at the spark plugs to see which one is wet with oil. That way you would know which cylinder is acting up. Then do a compression test to see if it's valve guides or rings.

Most of the engines I've had with oil burning problems have been rings or valve guides. I had one once with a badly worn out valve guide that would smoke pretty bad. It would also mess the spark plug every 200-300 miles.

Yep. Im taking it to another local shop on monday for a free eval/estimate

Then I am taking it to the people who did the work and asking them to make good on it if shop #1 can say they did something dumb (like advance my timing too much, whatever)

I`d check for carbon in the cap/on rotor,plug wires,and plugs.

Oh, the smoking... Its only after idle, im guessing oil is pooling up somewhere... running at 60mph limping home (Yea, I know thats not quite limping, but I had 60 miles to cover!) it was smoke free.
