I'm really sorry to be the one to tell you this, but the blue smoke is from the engine burning oil. This almost certainly is from bad piston rings. The engine needs to be replaced or rebuilt, because this problem will get steadily worse until the engine dies completely. You should have had the engine checked over before you got it.
Could be getting into engine. Check tailpipe emissions for white smoke.
One reason could be an extremely worn engine, another possibility is way too much engine oil has been put into the crankcase.
supercharger seals could be bad
There could be a couple of reasons why water is coming from a tailpipe. There could be a blown head gasket on the car or a cracked head. A small amount of moisture is a normal byproduct of the burning of gasoline in the engine.
If it's the inside of the exhaust that's black it could be caused by burnt oil in the engine.
One reason is engine overheating - check your temp gauge and coolant as a first step.
you could have a hole in one of your pipes or hoses that the water went throw.
If the engine is overheating rapidly and/or blowing oil then it could be.
Water coming out the tailpipe means there is water in the exhaust. This is not uncommon when the engine is cold and the exhaust is condensing. That situation should stop when the engine warms up. If the exhaust continues to have water in it after the engine is warmed up it could possibly indicate a leaky head gasket or cracked cylinder head.
It will overheat, and could end up blowing the head gasket.
Engine oil could be running too rich or rings!
The burners are not igniting for some reason. Could be a few different things, call a plumber.
