Jeep smoking when u first start it and when I exhalarate rapidly whats wrong

worn valve guides,and worn or clogged oil ring ports and grooves,restricted oil return ports in head,oil too thin or poor viscosity,bad PCV valve,broken ring on one or more pistons,bad head gasket between oil galley and combustion chamber...these are for oil smoke.it will be different broken stuff if it is steam from cracked head,or black smoke if its rich air fuel mixture,stuck choke,bad spray pattern from a fuel injector and un burned gasses as a result of poor spark and using gas additives that are not in the correct ratio or using your 2 stroke chain saw gas when you run out of gas in the Jeep. Or using that old and contaminated fuel from one of your other junk cars sitting in the front yard....I hope that narrows it down for you....kerrywac@gmail.com
