How do bellows valves work?
Bellow is similar to a hollow flexible hose. It functions like a vertical diaphragm (parallel instead of perpendicular to valve stem). It seals with the valve stem at one end, and seals with the valve body at the other end. Therefore, it allows a small relative move between valve stem and body, but prevents fluid from leaking across bellow surface. The move pushes seat or stem tip for valve to close or open. --SteveX

What is wrong with the car if there is blue smoke from the exhaust when you take off from a stop but it goes away while moving?
Hey Lynn==It is probably just tired and in need of an overhaul. It will probably chug along for some time but an overhaul is in order. GoodluckJoe sounds like you have leaky valve seals. They are letting oil into the cylinder when the car sits still. There are tools that allow you to replace the valve seals without taking off the heads. If you have or can afford the tools, this is the way to go. bad valve stem seals or oil return holes in the heads are blocked with sludge.
How will a car act if the valve stem seals are bad?
If the valve stem seals are bad the intake valves will "suck" oil into the cylinders. One common indicator of worn valve stem seals is to take your foot off the accelerator for several seconds when going downhill, then watch for smoke when you step on the accelerator again. If you see a puff of BLUISH smoke, you probably have bad valve stem seals. The catalytic converter can become oil fouled so that would be another indicator that you might have valve stem seal problems.

How do you stop oil from getting into the spark plugs?
if oil is getting into spark plugs, this indicates that either the valve stem seals need replacing,or the oil rings on pistons are worn and need replacing. if valve stem seals are the problem ,the vehicle will really be blowing a lot of exhaust smoke to the extent sometimes that it will look like a smoke screen behind you
Can you use oil treatment for bad valve stem seals?
No, oil treatment will react in the same way as regular oil. Replace the valve seals.
