are you burning oil? if so do a compression test first and if it's okay you can change stem seals on the car ...marc

If you're getting oil in your air cleaner that's getting sucked into the carby, then you're getting "blow-by", it's the rings. Valve stem seals will give a puff of blue smoke on start-up and then be fine while you're driving.

Compression should be within 10% of each other, but if it's below 100psi, it's alot worn. Squirt a teaspoon of oil down the plug hole and repeat each cylinder. If the compression rises, it's also a sign the rings are worn.

Yonnee.
