yes when the engine is out and upside down
The pistons and connecting rods have to be disconnected from the crankshaft, then removed from the top of the engine block. The oil pan and heads will have to be removed to gain access.
The crankshaft is the part that connects the flywheel and the piston rods on an internal combustible engine. Its job is to change the movement of the pistons to a circular motion, which is what is needed to power a vehicle.
Quite simply you have to remove the pistons. first drop the oil pan second disconnect connecting rod end caps third either remove crankshaft or remove cylinder heads then finally remove pistons. removing pistons are commonly removed from the bottom of the engine. they are pushed out of the top where the cylinder heads sit. Once removed you can replace the rings and then you have to get a piston ring compressor to reinstall the pistons.
I assume you mean to ask how difficult it is to change the main bearings WITHOUT pulling the engine out of the vehicle. Don't bother. To properly replace the main bearings you need to pull the crankshaft away from the engine far enough to be able to put a micrometer on the bearing surfaces of the crankshaft. To do that you need to disconnect the crankshaft from the transmission AND pull the pistons part way out. Also, depending on the type of seal used, many rear main seals must be replaced by pressing them into place after the crankshaft is in. Don't even try to replace bearings without first verifying the status of the crankshaft. It must be round and within tolerance. If the old bearings have worn there isn't much chance that the crankshaft hasn't been affected.

If your timing belt were to break while the engine is operating, the camshafts would be out of time with the crankshaft. This 'out of time' would cause the valves to open at incorrect times in regard to the crankshaft/pistons. This break in the timing belt could cause valves to bend or break as well as damage the head itself; pistons could also become damaged in the process.
The pistons must be removed from the cylinders to replace the rings. Therefor, you must disconnect the rods from the crank. No options no alternatives period
yes, you can.it's simple, all you have to do is just change it without removing the tank because there is more space available under the tank from the engine
The water pump on that neon is located in the distribution belt with between the camshaft and crankshaft pulley, you have to change also the belt, the problem with that is that it is really difficult to remove the crankshaft pulley, you need a very special extractor for that. Removing the water pump is really easy.
No. They intake and heads need removed.
yes, it is very simple. even a child can do it. If you don't know how to do it ask MORCHED He is famous for changing things without removing stuff.
Yes but extra work. Especially if it has the new sensors.
