Picked up a 93 xj that was sitting for two yrs with bad slave. Fixed it and now driving. It is smoking a little. White smoke. Its not burning oil and oil does not look milky at all. Hoping maybe sitting so long gaskets just maybe dried or shrunk. Hoping with some miles on it shell get back to good. I knew this vehicle prior to buying and it did not smoke prior to it being parked. Anybody have any thoughts? Maybe a Lucas oil treatment?

Personally I never like to use lucas. I've never seen it help anything. Check your pcv hoses from the valve cover to the intake and breather. Did you change the oil and filter already? If not id recommend fresh oil and filter. If those are all ok id just put some miles on it and see if it clears up.

I have fresh oil and new filter
Pcv line all good. Il rack some miles and go from there. Thanks.
