I have a 2000 Taurus flexfuel car the engine overheated and blew the head gasket and probably warped the head also. it was leaking water from the timing chain cover. my question is I found another wrecked 2000 Taurus with only 60,000 miles on the engine but it is not a flex fuel motor like mine is. it is a U=Vulcan 3.0 ohv mine is a 2=Vulcan ohv flex fuel engine. so can I just swap the non flex fuel engine with my bad flex fuel engine ? would I need to change the computer also or sensors ? any help I would be gratefull. I cant afford to buy a new car thanks for anybodys help. I don't plan on running ethanol in the car I never had before.

You'd also need to change the PCM and remove or bypass the fuel driver module which.
I'm not aware of anyone that's made the conversion from FFV to Vulcan and I haven't researched it, but I do recall there are differences in the fuel system, controlled by the PCM, that are there to accommodate the FFV options. I think the fuel type sensor is part of the engine so there's a good chance the Vulcan wouldn't run, or wouldn't run well, if you tried to leave the fuel driver and PCM in place.
It seems the FFV vehicles were rather common to see on the road. Are you having a difficult time finding an FFV engine in the salvage yards?
It seems to me that you'd likely spend less and end up with a more drive-able car to just fix the head gasket and have the head planed.

thanks ROD I guess I will start tearing it down to see if the cylinder has water in it. it was not blowing any steam out of the exaust but the pressure cracked my plastic water bottle and you could smell gas in the coolant and the scan showed a misfire on cylinder 2.

You could run a combustion gas analysis on the coolant to confirm if what you smell in the coolant truly is fuel byproducts. You might also try just pulling all the spark plugs and keeping track of which one came from which cylinder. If you have a cylinder that is burning coolant, the plug should look noticeably different from the others. In the case of one burning coolant, the plug would look quite a bit cleaner and might even have a greenish hue to it.
