Having worked on several cavaliers this year, I have found a tune up took care of the rough running condition, and all of them had valve cover oil leaks.
So consider replacing the valve cover gaskets and the spark plugs.

Is'nt this a front wheel drive ? If so , then your oil leaks from valve covers will be in front of car, and another closer to the firewall . In front of the driver and passanger compartment (under car ) . If it is on the right side and the left side of car, you might be looking at front and rear oil seals. Also could be your oil pan leaking. As for the running rough. a small tune up would probably work. Sparkplugs, sparkplug wires, Distributor cap and rotor, and new oil.... Goodluck.

1991 Ford Thunderbird leaving black stain on ground when I start my engine


Stain from the exhaust pipe, or liquid leaking? Exhaust pipe powdery stain from carbon buildup in engine. Either runs rough, needs plugs, or hasn't been driven fast enough to heat the engine. Insufficient information, check engine light on? Runs good? Other than stain, what else going on.

I am leaking coolant from somewhere. when I run my car, the engine smells like hot coolant. I have checked the oil, and the coolant isn't mixing with the oil. I have read about intake manifold...


First, I am assuming that your vehicle is equipped with the 3.1L V-6 and NOT the 3.8L V-6? (Engine size is really nice to know in situations like this!)

It could be any where in the cooling system. The intake gaskets also like to leak externally. A bad intake gasket does not always mix antifreeze with the oil. Take a flashlight and look for coolant on top and/or down each side of the transmission bell housing. This is VERY common on these engines. It may be leaking just enough to where the exhaust crossover pipe is burning it up (and stinking) before it has a chance to run on the ground. Also look for stains on the intake manifold-to block mating surfaces and on the side of the bell housing that will indicate a leak. if your vehicle is still using Dex-Cool, the stains will be pink. If your coolant has been changed to green antifreeze, the stains will usually be real white or dark green depending on the brand and the severity of the leak.

If there are no leaks or stains in this area, then look around the water pump area for the same things. The radiator or coolant hoses (including heater hoses) could also be leaking. If it is stinking when the engine is hot, then you could get it hot then shut if off and look for steam.

TIP: A bright LED flashlight works really good for locating steam.

Not quite sure where the leak is coming from. It seems to be getting bigger and in various spots. I seem to have various stains on the street where I park my car. What would the average cost of repair to...


Might be an oil pan gasket or a rear main seal?You have to put the make/year of the car and roughly where the stains on the ground are?,right under engine,under windshield area,front bumper,etc.Prices will vary from state to state and if your near a large city(usually higher shop rates).Try re posting with more info,someone can narrow it down a little more.Hope this helps you get a better idea.Good Luck
