Grady,

Can you please explain the difference between the deck height and squish area measurement.....if there is one?

My interpretation of these are:

Deck height - Distance from piston deck to top of cylinder at TDC

Squish area - Closest distance of the piston dome to the head at TDC, usually measured at the outer perimeter.

Are the squish and deck height measurements usually equal (as i hear them used interchangeably)?

I would think that squish can vary from one piston type to another (if keeping deck height constant) due to the different piston dome profiles/shapes, etc.

So, is the solder method for measuring 'deck height' really measuring squish area?

If so, you can see how the 1.25mm - 1.50mm 'rule of thumb' for measuring deck height using the solder method is a bit misleading.


Signed,

-Confused
