New Rebuilt but burns oil !!

I am a new member and I have a question.
I came across a trade of a 1965 F-100 style side pick up. Previous owner traded to pay off a debt to owner that I traded with. Truck has a 1969 T-Bird 390 FE motor. Motor was rebuilt by machinist that knows Fords.
(No paper work on motor) Engine has about 1000 miles on it. When driving runs great puffs a little smoke. When you turn right it smokes so much it looks like it is on fire.
Right side spark plugs 1-2-3-4 look good and clean. Left side plug 5 little brown, plug 6 black with oil, plug 7 brown, plug 8 black with oil. Compression 140 right side ---- 135 to 155 left side. Motor starts right up and runs at 180 deg has a 180 deg thermo.
I was told maybe intake gasket folded when edelbrock manifold was Installed.
Any advice ????
Ed

I've only been inside 1 390 & that was 30 somethin yrs ago,so,I may sound stupid.If it smokes like crazy when turning right,that would send all fluids to the left which is the side you seem to have problems with.If the pan had a windage tray or baffle that was misplaced or even left out.Just a wild guess.If the oil level were too high,I could maybe see this as well.Are you sure the dipstick/pan is correct?Scratch that !!! If that were the case,it should do it turning both ways.Sorry.Musta had a brain fart !!!

Bad valve guides or seals on the left side, turning right covers them in oil, leaks into the cylinders? Just a guess, not a Ford person. Whatever it is it has to do with oil movement to the problem side.

1. If you have not changed oil yet, then you have no idea if the dipstick is valid or not. Drain the oil. Leave the filter in place. Put 5 quarts in the pan. Pull the dipstick out to see where the oil level is on the stick. Re-mark it with the edge of a file if it's not valid. Maybe the previous owner used a stick that didn't belong to that motor.

2. Pull the intake manifold and inspect the gaskets for being pinched all the way around each and every port. If you cannot witness a pinch all the way around, then the gasket is not sealing up and the motor is pulling oily vapors into the cylinders. It is possible that the X and Y axes are not square between the manifold and the heads. If this is the case, then you have some machine work in your future.

I have been told the same from others. Somehow the intake gasket on the drivers side slipped or intake manifold is warped not compressing the gasket, causing oil to be sucked into cylinder through intake port.
Thanks for the advice, you guys are very helpful. I will pull the intake and replace gasket. Does anyone know if the port size is 1.10 or 1.34 as there are two 390 intake manifold gasket sets available ????
