I honed my cylinders and checked the gap of the compression rings.
The gap is between .015 and .016.
Does this sound about right to you ?
I was expecting it tto be closer.

If you honed your cylinders we assume you did it correctly and have a smooth crosshatch at one full X per the length of the cylinder. The cylinder hone is critical to a good ring seat and subsequent performance. Generally, not a DIY project at home unless you have proper equipment.

Proper ring gap (varies some by ring) is .005/per inch of bore for the top compression ring and .0053-5 for the second ring (more). The oil expanders should not be gapped and they should be staggered so all of the groves are not aligned.

All of the rings should be staggered around the piston so the gaps are not aligned at the time of install.

When you check the gap be very sure that the ring is square in the bore about 2 inches down and use 3 feeler gauges - go -fit-no go to measure.

Did the ring set has some gap specs with it?
NO I did some research and found the ring gap specs online
thanks

I built my engine to 1.6L specs, and ring end gap was set to .012" for both compression rings and oil ring gap was pretty snug around .017" too. I had the honing done at a local machine shop since the block had to be bored a bit.
