1989 lincoln towncarsmoke apears from the passenger of the motor when my car is off also my back wheel seems to jerk as l accelrate and it makes a buckleling sound while driving whats the problem and does it cost more to fix than to keep thank you for your timel apprecaite your time and knowledge to my problem

trade it for a cadillac

what does the smoke smell like? perhaps oil? exhaust? rubber?

The smoke could be a leaking valve cover gasket and the oil is dripping on the exhaust manifold. The jerking could be worn U-joints, bad wheel bearings, a rear end problem with the gears. That is the best guess l can give. Probably need to take it in and have a mechanic look at it, he could give you a better idea of the problem and the cost to repair.

The car is old it does not take a experince mechanic to figure this out its a old car and its probably seen its best days. With out seeing the car no one can tell you exactly what is wrong l would say it will cost more to fix then its worth and you are going to have more problems so just get rid of the thing.

Here is a few things they might help u out.

The smoke might be caused by a worn out valve cover seal as mentioned previously. That is cheap to replace. Which is causing oil to spill onto a hot part of the engine, causing the smoke. The 5.0L engines usually require new seals after the 150K mark & r usually bulletproof otherwise with regular maintenance.

As for the buckling & jerking my bet is on replacing the wheel bearings on ur differential, which is inexpensive to do on the live axle rear suspension. If u start seeing smoke coming out of the rear wheelwell, then l suggest u take care of this issue immediately to avoid further damage to other suspension components.

Overall as reliability goes, these vehicles r easy to work, the parts r inexpensive, extremely safe & with little maintenance can go a long way. This is the reason why for years taxi companies & police departments have racked up miles with this platform.

Hope this helps..
