I have a 97 regal gs that idles fine for about 10 min or so , then starts smoking from the back of the engine (firewall side) with no room i cant see where its coming from but it looks like its coming from around the exhaust manifold, but no oil leaks under the car. after another 5 mins or so of smoking it starts to rattle,after 2 mins of rattling it finally dies, but wont immediately start until it cools down. it smells like oil. head gasket already replaced. temp never overheats. is something clogged? please help
