I have a 2006 Ford Taurus that has white smoke coming out tail pipe. Oil not milky. could I have a cracked head.

Yes. some dummy put my thermostat on backwards. I thought that's why it ran hot and had white smoke coming out tail pipe about 4 months ago. Put bar's stop leak in it and it stop smoking. but now the smoke has returned. Also will that affect my injectors? Auto zone ready misfire on 1-4 I replaced coil pack But still reads 1-4 is misfiring

OK so what if my catalytic converter was gutted out??? Sorry for so many questions

And what should I do if because it doesn't handle the antifreeze well

I appreciate it tennisshoes u helped a lot

One more question. If I got a crack or blown head. What should I use to fix it

OK. Thanks again

I was following your question... Tennisshoes will that O2 sensor cause your car not to run? Before mycar stopped working i got it scanned n it said that was a problemy my engine light was on. BC the coolant level was fine not sure of the thermostat but it never ran hot. Having problems starting my 05 Mazda 6. Shut down while driving. N I've replaced battery alternator n starter
