I have a 92 Ford F-150 it has a 4.9L engine and is 4WD its overheating i think it may be a head gasket or the thermostat how can i tell? Smoke comes pouring out of the engine after not even driving it for a mile and theres oil leaking all over the engine looks like it could be a head gasket problem but i cant be sure....any suggestions?

Yes it's definately not the thermostat. Get that truck to a shop immediately (via a tow truck)

First, check your fluids. Do you have enough radiator juice? If not then fill'er up because this will be the first problem of overheating. Second, if you do have a leak find out where it is. Could be a hose, could be a head gasket; if you are mechanically minded and you are wanting to do more by yourself then read on, if not then you may want to take it to a shop that you trust.
If you are leaking fluid on the ground there could be a few possibilties: radiator, hoses, water pump, or a freeze plug. If you don't see the green stuff try running your defroster does it leave a slimy film on your windows, or give a sweet smell? Then it could be a heater core. If you find absoultly no trace then it is possible that you have a blown head. There are several suggestions that are a "shade tree" way of checking, but if you want to be sure for around $30-40 you can buy a head gasket leak dector from the auto parts store. You can be the envy of all your friends.
The leaking oil could be due to leaking valve cover gaskets or a push rod cover gasket or both. If the oil is up high on the motor then I would say that this is the most likely. if it is lower at the base of the heads closer to the main part of the block then I would say head gasket leak.
If your fluids are full then check out your t-stat. In fact it is cheap enough I would just go ahead and replace it because it is under $10.
If you still have problems after this then you might have a plugged radiator, water pump impeller that is broken, hose collapsing, fan clutch not working, or a guage that is not working/sensing right.
Good luck.

Start by checking these five things. 1. pull your oil stick - if it looks ok and is not a grey milky color chances are it is not your head gasket. 2. when was the last time you changed the radiator cap (a weak radiator cap can cause the problem. 3. Change the thermostat it could be sticking or stuck close. if have already changed the thermostat be sure to "burp" your cooling system by turning your heater on and running the engine with the radiator cap off so there will be no air blocks in the system. and 4. check the timing. 5. if you have a clutch fan check it and make sure it is providing enough air flow. hopefully that will give you a start

to check if it is the headgasket, take the radiator cap of the vehicle whilst it is running (make sure the engine is cool). If the water is bubbling and/or frothy it is most likely the gasket. To check the thermostat simply take it out of the housing and drop it in boiling water. If it opens, its fine . If not its stuffed. Sounds like a gasket

Does your truck overheat once you're making use of? it won't.. comfortable hose frequently potential there is air interior the device or now pass of water. replace the thermostat and slowly top off the coolant device initiate the truck up look for leaks, permit the truck run at idle for about 3-5 minutes, close the truck off, slowly open the radiator cap (rag over it) to furnish your self with protection, you could hear air escaping out of the device. get rid of the cap thoroughly suitable up the device as mandatory.

What a lot of ( it's definitely this or that).Are they standing over it looking down?If it's getting hot in less than a mile check your radiator and if it's not hot then it might be the thermostat.I'm not saying it's not a head gasket.By the way you describe it makes one think thermostat.The oily mess could come from valve covers especially after getting the engine hot.May not be as bad as the ones above me say it is.But then again it could be.

its defiently your head gasket, I know someone personally that has the same issue but on a different car.
it costs atleast $500 to replace.
also makesure you have antifreeze coolant just to makesure its not your gasket and you just have low levels.

quick check. when it has cooled down (just saying because some people are that dumb) check your oil and antifreeze with a blown HG usally their will be oil in the antifreeze and you will be able to notice water droplets on the oil dipstick...

check the oil, if its got antifreeze in it you blew your head gasket.
