white smoke out the tail pipe

[drumyn29]

To test for bad rings, run the car down a hill at speed and let off the gas completely for a way till the car slows to about 15 MPH. Shower down on the accelerator and watch the mirror. If it smokes, you have bad rings or in the case of an overhead, bad guides and seals. This is because when the throttle butterfly is closed, the pistons will cause a vacuum and suck oil into the cylinders in a loose motor and when it is opened it burns it making lots of smoke .

Is there a special oil that I can use that won't smoke? Or an additive? I'd like to enjoy the car a bit before I rebuild the motor.

use full synthetic it burns clear and remember there is still some in the dipper tray so change it out twice after running it

I haven't had a chance to do compression but it's on my list. I've used synthetic in the past on other cars but wasn't sure if it's good to use on model A's.
