2001 Sable, Vulcan, Smoke from right rear of engine.
Long story short, Overheated the original vulcan and replaced it with a 7x,xxx mile vulcan from an 02 taurus. I looked over the engine before I installed it and didn't see any oil leaks, in fact the engine was fairly clean.
The problem, First start in the morning my wife has a long steep climb to get to her Job. The car will start smoking from the right rear of the engine(Approximatly where the rear manifold joins the exhaust pipe) about 1-1 1/2 miles up the hill. I am kinda thinking that since the engine is relativly low miles, it has been sitting a while before I bought it and maybe the rear valve cover gasket is dried out or cracked causeing a slight seep. The car also sits on an incline overnight so maybe a little oil leaks on to the rear manifold overnight causing the smoke to be more promenent first drive in the morning. I tried looking behind the engine for leaks but the upper intake gets in the way of a good view. What I can see looks clean and dry.
It is also very hard to diagnose because she allways takes the car in the morning, May need to get up on a weekend and take it for a spin up the hill. I have driven the car up the hill after she gets back from work with only a small amount of smoke after I open the hood at the top, no noticable smoke while driving. I know its not antifreeze but it also dosen't seem to smell like oil, More like burning rubber that burns your nostrels and Eyeballs.
BTW, the smoke clears up after she gets on a level road making me even lean more towards the rear valve cover gasket.
Any commen leaks on these engines in that area or am I just going to have to start replacing gaskets? Starting with the VC gasket.
