Yes!
If there is oil getting to the top of the piston and burning then you have a blown head gasket or the piston rings are worn or broken. Engine must be disassembled.
The broken bolt can be blown out by someone who knows how to use a torch - muffler-shop
You will have a smooth running engine when the rotating assembly is balanced.

If the timing belt has broken the engine will not start. If the belt broke you will have internal engine damage as this is an interference engine. The belt must be replaced every 60,000 miles. a quick way to verify if the belt is broken is to remove the distributor cap and turn the engine by hand. If the rotor does not turn the belt is broken. You can also remove the oil fill cap and look at the valve train. If you see no movement when the engine is turned by hand the belt is broken. Of course if the engine is locked up the belt is broken as the valves are hitting the pistons. quick way to confirm a
You must replace the piston rings. That means TIME FOR A REBUILD.
The piston crown refers to the top of the piston. A piston can generally be divided into two sections (though the piston is a single piece). The lower part of the piston is called the skirt. The upper part, including the top of the piston that faces the valves and must handle the combustion of the fuel-air mixture, is called the crown. The piston crown must have the mechanical strength to withstand the forces of combistion, and must be made of materials that will withstand the heat of combistion. All this must come in a package that has limited thermal expansion so that the tolerances within the engine are tighter and performance is maximized.
It is not possible to fix a broken needle. You must remove the broken one and replace with a new needle.
To remove the gearbox from a Volkswagen Polo the engine must be hoisted out of the car. Several of the engine components must be removed including the exhaust manifold and clutch lines. The gearbox is held on by several large bolts to the engine.
You must remove the Timing chain cover and engine girdle.
It is between the transmission and the engine, You must either remove the engine are the transmission to get to it.
um this should be left to a pro stricklly because the plug hole will need to be re- threaded and the piston must stay free of deposits during this period but if your workin on the old mower try an extractor set a good on not no wal-mart junk go to sears or depot
