Air coming through the valve cover

Ima thinking that would just be an intake gasket, and she's sucking oil from the valley? How well does it idle?
Put a vacuum gauge on the dipstick tube, Pull out the breathers and plug the openings. Start her up.
Vacuum means intake gasket. Pressure means a ring problem.
Or possibly brake fluid from the booster? Check the fluid level.
I would at least check those before tugging her out.

She starts right up and idle's by herself. I'm thinking you may be right about the oil if it was having trouble breathing right to begin with adding a heavier weight just stressed her out a bit more. anyway live and learn I just broke the news to the wife she is not getting anything for Valentines this year. she loves my car!:lol:
