What in your opinion is the meaning of "seized" in this small sentence?

Question

Engline smokes blue due to baked up piston rings, seized (partially seized) piston, worn cylinder units?

Answer 1

In this case, it means the the engine parts froze--they cannot be moved--they are stuck. In this case, one of the pistons is stuck.

Answer 2

Here's a detailed explanation of piston seizing:

"Seizure is a case of scoring where the oil film does not immediately return. After a few moments of
constant scoring, the piston and cylinder will scratch each other hard enough to remove material from each other. This floating material grinds itself into the piston and the cylinder as it continues to grow
in size. As this snowballing material grows, it will drive the opposite side of the piston against the
cylinder wall with a pressure so terrific that scoring begins to take place. While all this is going on,
your engine is still running wonderfully at full throttle.
The death blow comes when the mass of material between the piston and the cylinder wall finds it's
way to the piston ring. This nearly molten mixture of aluminum and iron will instantly lock the ring in
it's groove. This ring locking, not the piston surface seizure, is what actually causes your engine to
quit. When the piston ring becomes locked back in it's groove, it's incapable of providing
compression sealing against the cylinder wall. This instant loss of compression, while the engine is at
speed, causes a dramatic loss of power. That power loss, along with the added drag of the badly
seized piston, makes the engine quit or lock up in a nanosecond. In fact this entire seizure process,
from the first scoring scratch to the piston locked solid, takes less than a second at full rpm."

In general, the word "seize" in this context means that a mechanical part is "grabbed" one way or another and prevented from continuing to move.

Answer 3

Mechanically when something "seizes" it means it no longer will move. If the engine is running and a piston seizes (i.e. stops moving up and down), it could overheat the oil in the cylinder and create smoke. I used to work in an office adjacent to a military vehicle maintenance shop and saw work orders with similar wording. I always got a chuckle out of "Engine Missing" entries. Of course, the engine was not missing as in gone, but missing as in misfiring or running poorly.

Answer 4

It means the metal piston melted down from the over heat and is infused (attached) to the block of the motor preventing it from moving

Answer 5

I think the pistons are seized and won't move in the engine.

Answer 6

The piston is in a static position and not moving up and down like it should.

Answer 7

Stuck the piston is not moveing freely

Answer 8

The piston is frozen in place and will not move like it is supposed to.

Answer 9

caught or partially caught.
