Head gasket. Just starting to go and as the motor warms up it expands and seals the gap. Oil is getting into the coolant and since oil floats on water it goes to the overflow. Lack of speed, one or two plugs are fouled or you are loosing enough compression on 1 or 2 cylindars.
Pretty much has to be a blown head gasket.
Most likely you have a blown had gasket.
Assuming you have not noticed and leaks or puddles near the car the next thing would be to watch for steam coming out of your tailpipe. If there is you probly have a bad head gasket.
Runs rough, water coming out of tailpipe if I was a betting man I would bet my last twinki that you have a cracked head or head gasket. water is crossing over into your exaust valves causing the water to come out of your tailpipe and the decreased power in the runs rough is from the compression leak. I am willing to bet that when your engine is running and your radiator is full along with your overflow you have bubbles blowing into your overflow if everything is not full fill it annd check.
Most likely a cracked intake manifold.
Probably has a cracked block, too :(
I'm not a mechanic / technician but if white smoke is coming out of your tailpipe with the engine warmed up it sounds like you are getting engine coolant into one or more of your engine cylinders . ( bad head gasket / warped cylinder head ) Is the coolant / antifreeze mix also going into your engine oil )
White smoke is caused by water and or antifreeze entering the cylinder, and the engine trying to burn it with the fuel. The white smoke is steam. There are special gaskets (head gaskets are the primary gaskets) that keep the antifreeze from entering the cylinder area. The cylinder is where the fuel and air mixture are being compressed and burned. Any amount of antifreeze that enters this area will produce a white steam that will be present at the tailpipe area. If white smoke is present, check to see if the proper amount of antifreeze is inside the radiator and the overflow bottle. Also check to see if antifreeze has contaminated the engine oil. You can look at the engine oil dipstick, or look at the under side of the engine oil filler cap. If the oil is contaminated with antifreeze, it will have the appearance of a chocolate milkshake. Do not start the engine if the oil is contaminated with antifreeze, as serious internal engine damage can result. How did antifreeze get in the oil or cylinder in the first place? The engine probably overheated and a head gasket failed due to excessive heat, thus allowing antifreeze to enter the cylinder (Where it is not meant to be).
Probably a blown head gasket and/or a cracked head.
Antifreeze will burn; however, if it's been diluted with water 50/50 (which is how it's used), the engine will not run very well at all and there will be a lot of white smoke from the tailpipe.
A cracked engine block
