Burnt oil

Have you tried a seafoam treatment? With the motor idling, slowly pour a can of seafoam down the carburetor. When it dies, pour the rest in and roll the motor over a couple times. Let it sit for 20 minutes. Start it and go spin some brodies until the smoke clears up.
That might not do any thing either. It's worth a try though.

I had the heads cleaned when I tore it apart. I put new plugs in with the correct gap. I did not replace the wires cause they didnt look bad or that old. I wonder if I dont have the distributor adjusted exactly right. But anyway.....I figure the only time it'll idle is at the stop sign, so I would just burn alittle more gas. Right?

I am running 10W-40 in it. I havent added any oil to it all summer. I was a bit low on the compression range but still in the range according to the manual. The vacuum gauge in the truck was showing normal(accel, idle, dece accordinglyl) when I first put it back together. Short time later it dropped off significantly. I figured the line from the intake manifold was leaking as it appeared to be older and I havent replaced it yet. Do you think I have a significant vacuum leak? How can I find the leaks? obviously soapy water isnt going to work....

Hey Scout,
I was having trouble dialing in the timing once, getting it to my 302's specs, which is somewhere around 600-700
if memory serves...it turned out to be a vacuum leak with the intake hose to tranny....just enough of a leak to be
"a fly in the oinment" as Grandpa used to say.
Ultimately, I cannot understand how oil could be burnt unless it was running really hot??... your idle speed is
still well below normal operating rpms.
I'd really chase down the timing/idle rpm issue first...you should be able to get it idling well below a 1000...as far as
finding/solving leaks, my philosophy has always been simple...throw enough money at the problem and it always
goes away...hoses are cheap, and these trucks have only a few of them...I'd replace them and start from there.
Good luck Mate.
Best,
Jason

Listen for the hiss of air out a leaking hose. If you suspect the base gasket of the carb is leaking spray some starting fluid at the base - at idle speed. This will momentarily change the engine idle. Replacing vacuum hose is easy and cheap. If there is any rigidity in the hoses don't hesitate to replace it.
Did you use all new gaskets when you "put it back together"? As to compression you want all cylinders to be within 10% of each other regardless of the "range"
