smoking 3000 gt

my 95 3000gt is smoking after about 30 minutes of driving. Smokes mainly when idle and upon acceleration. car has about 200k in mile. what could cause this.

My first guess would be worn valve guides and/or valve seals

You have bad valve stem seals. 99.9% positive. Not a big deal but something that will need to eventually be taken care of.

Definitely a valve seal issue. Common issue on 3s's

Even though your valve stem seals are bad, go with a good PCV, so burning more oil doesn't add more to the problem.

Keep your Auto running Greener for longer than 7years/100Kmiles, see http://www.ideabuyer.com/ipavail/acme-auto-emissions-filter

By good, he means OEM. The auto parts stores PCV valves are built backwards.
