Blue indicates a lot of engine oil is being burned, black would mean too much fuel, and white would mean excess water/coolant. Being as it's blue, it could be any one of a number of things, all internal in the engine. Could be bad oil rings, valve guides, stem seals, etc. I suggest an engine shop to properly determine the cause. Might just be a plugged pcv system that just needs cleaning, you never can tell from the outside. Is there a lot of oil in the air cleaner assembly? If with the engine running, you carefully remove the oil fill cap, is there a lot of pressure/gasses escaping? There shouldn't be.

Blueish smoke out of exhust,no power, puddle of oil under car, smells like raw fuel out of exhust

Hi , it sounds like your valve stem oil seals need renewing. If you mix oil with petrol it does not all get ignited hence blue smoke from the oil and the smell of petrol out the exhaust.

My 1985 mazda rx 7 1.1 gets glowing hot where exhust comes out of the motor , replaced exhust pipe and muffler but didn't help have any suggestions

Check the ignition timing.
Make sure the fuel you are using is specified for engine use.
Last one will be to check the catalytic converter if it still open.

Hope that helps!

It sounds like you have alot of problems which may only be a couple.
Have the coolant thermistor checked, it sounds like this is not switching off and causing the engine to over fuel, making it run rough and blow black smoke out the exhaust.
Have the engine thermostat checked it maybe faulty causing the engine to over heat., have these done and see how you cars goes then.

The engine 4.6 gets alot of smog,I think,the problem maybe wil be the regulator presure of fuel pump. Because was liquing gasoline throw the mofles . Do you agree? It ocurres about one minute after I...

If the smoke is white, it is caused from burning oil. It it was gas it would be black. If the smoke is coming from the exhaust pipe then the oil is leaking into the combustion chamber of the engine. If it is coming from under the hood then there is an external leak that is getting on the exhaust system and burning off.

How do i find where an exhust leak is coming

check where the headers come off of the engine exhaust leaks are generally quite loud and you will either be at the headers/exhaust manifold or just as you come off that bend there will be a flange gasket inside the two pipes joining. from the bend to the straight pipe just as it passes the gearbox and starts to straighten out.
