Sorry this was not responded to sooner. Yeah, sounds like you have a leak in your exhaust manifold, maybe a spent catalytic converter. Also, the blue smoke is usually indicative of burning oil. I'd make sure your oil level is not dropping, maybe remove your catalytic converter to see if it has been compromised by its long tour of duty. If your exhaust is the original unit, and therefore 25 years old, I'd say you have definitely gotten your money's worth.

Sounds to me like valve stem seals.Ageing OHC engines suck oil right though old dryed out valve stem seals.They can be changed and engine returned back to near normal,with some effort.
