Measure Bore without pulling heads off?
Hi Guys,
does anyone know of a way to internally measure the size of a cylinder bore and stroke (to determine engine size) without dismantling an engine? Is
there some small laser/3D imaging tool or camera that can be inserted in the spark plug hole?
My T1 engine number suggests it is a 1600 but I suspect it is bigger.
Cheers

I would think that you could measure the stroke by putting something long (e.g. a push rod) down the spark plug hole and mark the two most extreme
points of the stroke on the rod
Measure the distance between those two points and you have your stroke length?
Hope that makes sense.

Years ago I saw a go kart scrutineer test capaity by connecting a machine to the spark plug hole and spinning the engine. Perhaps talk to a go kart
racer?

You could get a piston at the bottom of it's travel, disconnect the rockers for that piston so as to close the valves and then fill the cylinder with
a thick enough liquid that won't quickly seep past the rings. Then you'd have the volume of a cylinder. Then divide by the stroke of the piston back
to TDC and you get the area of the piston.
If you can figure a way to do that with compressed air then probably be the cleaner way to figure it out. Otherwise, as with any engine (even non-AC)
you have to remove a head to measure things.
