Your engine may be leaking oil down the back side of the rear main seal, and burning off the exhaust manifolds. You may need to take a look at your brake and power steering reservoir to insure the level is correct, and not leaking out of a hose

From your experience, you know that the valve cover gasket leaks motor oil on to the hot exhaust which will burn off, making smoke from the back of the engine block. Perhaps you have another leak coming from the gasket. Or you have another fluid leaking back there, making the smoke. With out looking, it is not possible to tell you the cause. If you can not see the leak yourself, check out the auto shops on the askpatty.com site. Ifs possible your car will need to be raised up on a life to pinpoint the leak.

Visit a mechanic to determine where the leak is coming from

Hello Vivian- I would say at 261k you have gotten a tremendous amount of life out of that engine it has far exceeded the service life of any non-diesel Chrysler engine - it is probably time for an new or rebuilt engine - hope this helps; thanks Super Girls Auto.

If the engine is smoking from the back it either has a leak or something is leaking onto the hot engine and burning.
It*s possible that your valve cover is leaking. I usually replace my gasket every time I replace the plugs...which is about every 60,000 miles. Because that rubber is subjected to high heat it can go bad and cause leaking.
Have a technician diagnose your problem so that you don*t have a bigger problem down the road.

Normally, smoking issue is an oil leak. Most common is the valve cover or intake manifold. Recommend having a technician inspect the issue and give an estimate for the work needing done.
This has alot of miles, and depending on the outcome of the cost to repair, you may have to way whether or not you*ve got your monies worth out of your investment?
