Hi
This is a ga16 rod metal
It was recently rebuilt with new oem nissan parts, correct tolerances and assembled by skilled persons
It only had 400 km break in kms...
Oil press varied (hot) from 20 psi at idle to 80 psi at 3000 rpm
Suddenly started a clunk noise rpm related, we disasembled it and this is what we found
In all my amateur mechanic years I've never seen something like that
Any ideas?
All other metals came out light worn, and the rod/crankshaft measures correspond to the metals used
