I just recently did a complete 2L engine overhaul and installed forged JE-Pistons with Biral Cylinder Liner kit 96 mm bore. The compression is fine, the engine runs well but I experience a consumption of 1 liter oil per 1.000 Km. After I checked the combustion chamber I found too much oil deposits on the spark plugs and the pistons. The ring gap of the piston rings is in tolerance so I wonder why there still passes so much oil from the crankcase into the combustion chamber.

Yup looks like a leak down test will tell you…..rings or valve seals.
