Hi,
One would need a LOT more detailed information to offer anything constructive.
Things such as:
Piston to cylinder wall clearances
Ring gaps
Leakdown figures
Valve-stem-to guide clearances
The rings should have seated by 2K if the cylinders were properly deglazed and correct break-in procedures were followed.
Teflon guide seals are well known for passing more oil than the factory Viton ones and for those reasons, we do not use them except in special circumstances.
