I'm installing a piston set in a Skoda Estelle 120 engine. I know this is not a definite way to measure piston to deck clearance, but it jumped to my mind to measure it with a vernier caliper using its rod to measure depths: all pistons are about 1.4 mm under the cylinder liner top. This is what the manual says:
Bore x stroke (mm): 72 x 72 Cubic capacity (cc): 1174 Compression ratio: 9.5:1
Not a word about piston deck clearance. So question is: is 1.4 mm under deck acceptable? I know it affects compression...would it mean it will be a bland engine? What PSI a compression test would yield, more or less?
EDIT: this ain't Porsche :) but I'm reading in Porsche 911 the deck height should be between 1 and 1.5mm, with a 75 mm bore
