Hi Anonymous,
It probably depends how far you drove after the car overheated. It is extremely bad news to drive an overheated car.
Typically the head gasket (between the cylinder head and the engine block) will warp when the coolant goes dry and the engine overheats. And then it leaks - both on the outside of the engine block and with big white smoke out the tailpipe.
Replacing the head gasket is doable but expensive.
But if you don't see any leaks on the block or white smoke you may have dodged a bullet.
Hope this helps,
Bud
Sounds like a head gasket leak. Have a cooling system pressure test and cylinder leakdown test performed. In the meantime, you should NOT drive this vehicle or you'll cause more damage.
The white smoke is probably steam caused by coolant getting into the cylinder(s) either from a faulty head gasket, cracked cylinder head or cracked engine block. The loss of heat from the heater indicated that coolant was being lost..
Check your coolant!!! White smoke is a sign of antifreeze getting in the combustion chamber. Very bad if it is. Don't drive it, get it checked.
(Pressure test the coolant system is the best way)
I don't drive a Ford but I drive an International and white smoke on start up means the engine is too cold to properly burn the fuel. Your black oil or soot is unburnt fuel. You should look at your engine's preheat system for a malfunction.
Hello!
There are two differnt reasons for black and white smoke coming from the tail pipe.
Black smoke means fuel runs rich (car getting to much gas). Check fuel pressure/air filter.
In some cases the white smoke means car is burning oil or transmittion fluid. Have tem checked/replaced.
If you can feel a smelly smoke it can be catalytic converter.
In a worsest scenario if car blowing white smoke it can be engine coolant is getting into an engine cylinder from a bad head gasket ,or a warped/cracked head. So you need to keep your eye on coolant level and check your engine for overheat. Also might be good to check your oil for traces of coolant (on a dipstick it would be a milky substance mixture of oil and coolant).
Good Luck
quick fix to sell it is to mix some casting plaster and pour it down the plug hole but be quick as sets very very quick it wont las long but it will last long enough to trade motor in
