Checking Piston Ring Measurments
One evening I had a little time, so I decided to check the piston ring measurements. First I checked the ring end gap for the first and second rings. The gap is important to ensure the ring doesn't bind up due to heat expansion - of course too large a gap will compromise compression...
All of my rings had a gap of about 0.022"
Next I measured the clearance of the grooves machined in the pistons - which is about 0.0025"
