98 GTP burns a ton of oil.
 

Hey guys. New member. I recently brought a 98 GTP and I put about 500 or so miles on a week. Most interstate at about 80MPH. I am consuming 3/4 - 1 full quart of oil in that time. It puffs a ton of smoke on acceleration. I’m at about 156K. I was thinking intake gaskets were shot as this is a large failure.

Any insight or thoughts would be greatly appreciated. Thank you.
