How do I repair a 1993 Mazda MX6 that is smoking blue smoke? I have replaced the PVC valve with a new one, the compression is good and there is no oil on the sparkplugs.

Engine is consuming oil and the spark plugs would be covered with carbon in no time.

Possible causes are bad oil rings and/or valve seals.

I would start with replacing the valve seals if it is not necesssary to remove the cylinder head.
