We are debating if we should just quit trying to fix it or try to find the problem.
I will say I think there are oil problems and possible transmission problems. The fluids keep disappearing . Thanks Lori
Compression test reveals condition of the pistons, cylinder walls, valves, and valve seats in the cylinder head. If the numbers vary greatly, internal engine problems are indicated that would need to be addressed before worrying about anything else.
Rich running can be caused by a sensor (like the oxygen sensor, for example) that has failed, or one or more leaking injectors, or an air control malfunctioning, a bad fuel pressure regulator, and other stuff too.
If the disappearing fluids are being sucked into the engine, that may account for the rich running too. The color and odor of the smoke are clues to what those fluids may be.
