That would be carbon build up, This usually occurs when the car has been sitting for awhile it will go away no worries.

Parkview camera not working any longer. Bought vehicle new in 2011, no rear end collisions.

No doubt, you have lost a connection. It's most likely a ground connection because the rear of the car gets the most abuse from rain, road grime, rocks, etc. Specifically, use a 12 volt trouble light to find the red or black power line. Ground wires are green. If you can't get 12 volts using the ground to a 12 volt source you've found your problem. Unless you're familiar with electrical systems you should be able to find a local car mechanic to help. If you DO know about electrical then replace the ground wire if it's not getting a good ground.

Black smoke from tailpipe, loss of power, anyone know?

What year, make and model car is this? Most likely, black smoke is
usually a carburator problem. If it's fuel injected, black smoke can be caused by 1) leaking or faulty fuel injecters, 2) faulty choke, 3)dirty air
filter or 4) faulty distributor cap and/or rotor. Hope this helps.

Oil loss in 1990 Honda Civic

its probably one or 2 pistons and there respective rings allowing lots of oil get by and then burned in the combustion chamber. it could also be valve seal but you would not be consuming that much oil and it would generally only be visible at first startup. The cause of it is simply the fact that it's an old engine and old engines subsequently break down in various ways. If you want to test the engine then do a compression check and see what kind of numbers come back. if any 1 or more cylinders is real low then you know which cylinder the oil is being burnt in. drop a little bit of oil in each cylinder and then retest. if the number bumps up significantly then that would be a sign its the rings. if the number remains low and unchanged, then that would be a sign of the oil coming in through the top end. unfortunately, whatever the problem is, it's going to require an engine overhaul. since these engines are a dime a dozen i would recommend just finding another used engine and dropping it in.

it's been my experience that when that happens you almost certainly spit a couple of teeth on your timingbelt/chain/gears.
