Remove the head and disconnect the connecting rod. Spray a liberal amount of penetrating oil on top of the piston and let it sit for several hours. Using a piece of wood and a hammer, tap the top of the piston until it is free.

Why there is rings in piston?
The piston rings create a seal between the piston and the cylinder wall.
Is piston slapping good for a race car?
NO! piston slapping is caused with the piston is to small for the cylinder wall and is smashing into the cylinder wall. this could damage or ruin your engine if you take care of it right away, especially a race car.
Would big end bearing knocking on ford cvh engine cause cam shaft to sound tappety due to low oil pressure affecting hydraulic tappet adjusters?
No. Your piston(s) are hitting your cylinder wall. No. Your piston(s) are hitting your cylinder wall. No. Your piston(s) are hitting your cylinder wall.
What do you look for in a seized engine?
Piston seized to cylinder wall Broken Crankshaft
Why piston rings are too loos on piston?
gas pressure has to get round the back of the ring to force it against the cylinder wall
How much clearance is allowed from the piston to the cylinder wall on a 2000 YZ 125?
Well...... you need A LITTLE bit of clearance for the gas mixture to lubricate the piston and cylinder. Plus your piston expands when it gets hot.
What causes blow by?
Blow by is caused when combustion gases get past the piston into the crank case. The cause will be piston, rings, or cylinder wall.
What is total effective piston area?
wrist pin to crown . the area of cylinder wall the piston travels ,shirt to upper ring groove
Will a scratched piston effect combustion?
Yes, a scratched piston will cause problems with compression. It scratches the cylinder wall and causes wear on the rings.
What causes engine blow by?
Blow by is caused when combustion gases get past the piston into the crank case. The cause will be piston, rings, or cylinder wall.
What is the difference between piston and plunger?
The difference between a piston and a plunger may be understood if you observe what forms the seal that precludes the fluid from passing either the Plunger or Piston. The 'piston' is a steel block equipped with elastomers that makes wall contact with the cylinder wall. As it moves inside the cylinder it wipes the wall and displaces the entire content of the cylinder. In this case the seals form part of the piston. The 'plunger' is a steel block that moves through a hole that is equipped with elastomer seals. The plunger displaces a portion of the cylinder contents, i.e., the volume of the plunger that enters the cylinder. The plunger does not wipe the walls of the cylinder. The seals, in case, are a part of the cylinder block. Umair Aslam Mechanical Engineer PARCO, Pakistan
What allows the piston more efficient cooling?
A larger piston skirt to cylinder wall contact raises piston cooling. With turbo motors, they have piston oilers, they spray oil on the underside of the pistons, cooling the piston /crown.
