The compression check.

Full result and my view reported back to the owner.

Looks like the valve seating got better compared to years ago due to long-long distance covered in one long trip with wide variety of rpm range used.

If driven regularly and measured at the same place, one should expect very consistent compression result each time.

For example, I have been taking compression on my NSX every year since new and using almost the same Eng oil spec, tool, procedure, etc
that over 25 years with more than 160K miles, still very consistent data since new even moving from Japan to UK.






























I'll let the photo to speak by itself for some of the findings.
