After rebuild 1500 km
I removed my engine to inspect all parts and see if my project good or something wrong
Checked pistons, rod bearing, rods, sleeves , camshafts All good But I checked cylinders leakage test With camshafts out Share with you results And i am confused thats normal or not Cause i know fresh engine leakage normal from 5-10 % only My piston rings gab first .060 And second .065 All cylinders Tdc

Is this all on the same bank the way you numbered them?
How did you break the engine in? Boroscope of those cylinders?

- TDC for cylinder tested? - Cams timed? - what exactly was the break in procedure? - could you hear air escaping while conducting the test? If so where? 60% leakage is pretty bad.

A cold engine will effect results. Usually you Zero out the gauge with the regulator before you connect to the line in the spark plug hole. Once you connect it gives you the percentage loss. Just want to confirm you did that.

I missed this before, yes if you were introducing the air directly without Zeroing the gauge and you cranked it to 70 and the gauge on the right read 60 then yes that would be 10% loss if thats how you did it, which wouldnt be bad for a cold engine. But if thats how you did it.

You're suppose to do this all with the engine warm for accurate results. I honestly don't know why you guys even went to the lengths you did to tear apart a good engine. All you've done is introduced issues now for no reason.

Tough to see in the pictures, but does it
Look like oil is getting passed the rings?
