No way of telling as it'd depend also on the size of the frame. For all "normal" applications chains are sold a tad longer than needed, and are cut to length on assembly on bike.
No way to tell. Also depends on the size of the driver and the length of your chainstays.
Chains are generally bought a little too long and then cut to size.
The chain length needed is determined by chainring size, sprocket size and the design of your frame. There's no way of saying that you'll need from the sprocket alone. On top of that there isn't much to choose from when it comes to half links. They are all of the same length and in width there are two options 1/8" or 3/32". You need one the same width of your chain.
well if you have a 8 tooth rear driver you will need a 23t sprocket, if u have a 9 tooth rear driver you will need a 25t sprocket, if u have a 10 tooth rear driver you will need a 28t sprocket, and if you have a 11 tooth rear driver you will need a 30t sprocket

You need a chain meant for single-speed or internally geared bikes, cut to the right length.
grind off the pin that holds the links together and grind off how many links you need and just put a master link on it
Most single-speed bikes(particularly BMXes) use a chain that is 1/8" wide. Chains are always bought a bit too long, and then cut to size. Use a chain breaker tool. No one can tell you how many links you need, it depends on the chainwheel/sprocket combo and the size of the frame.
the marks have to be pointing each other in the center of the gears
There's no way of telling, as chain length is decided by frame size (=chain stay length) + driver + sprocket tooth count. Chains are always sold a few links too long, and are then cut to size when they're installed on the bike. If you're doing this yourself, get a chainbreaker tool. For what they cost, they can sure save you a lot of swearing.
There's really no telling, it depends on what size your sprocket and driver/freewheel is, and the length of your chainstays. Chains are always bought a little too long, and then cut to size using a chain breaker tool.
Half links only come in two sizes, 1/8" and 3/32". Which one you need is determined by which chain you're running. Depending on which sprocket you had before a half link may not be enough. On a bmx just make it fit, they tend to slack by half an inch to adjust while peddling back since they don not lock. Meassure until nearest like possible.
right in front of the crankshaft pulley beside the oil filter....is the timing chain cover(two timing chain...#1 on the crankshaft sprocket, #2 on the cam sprocket. Need to lower the engine to access the timing chain. Timing chain, not necessary to be replace, unless they broke loose.Other than that it remain with the life of the van.
The bent sprocket is guiding the chain diagonally causing it to be unparalleled with the front sprocket, you will either need to purchase a new rear sprocket or find a way to bend the rear one back straight
