Hello
Thanks for the donation
Blue and black smoke indicates burning oil. Oil is leaking into the combustion chamber and being burnt out the exhaust. You will have to tear the engine down to inspect the internal parts. Worn piston rings would be the most common to cause this but there is no way to tell without inspecting engine internally.
