At the moment i'm running forged engine without turbo . I'm facing a problem with the oil . No smoke but the oil is dissapearing and there is no leakage around engine . I'm loosing about 600ml oil each 1000km . Any ideas?

Did you measure the block and ring gaps when you built up the forged bottom end? Worn valve guides are another area that could mean it's burning oil.
Check your breather hose for signs of oil as well.

Hi!
The ring gaps were 0.30mm for all cylinders. Normal signs of wear . Before the engine was running well . The cylinders head was refreshed (valves oil retainers changed and valves seats refreshed . Might be a point that i did not changed the valves guides. But there is no smoke on the exhaust . Maybe i have to check the exhaust manifold for oil .
Also a thicker head gasked was fitted (By mistake). I think was megane rs and the cr its lower than 8.5:1 at the moment . Cylinders pressure it s between 8.7- 9 bar on all cylinders . I don t know what is the normal pressure on this setup so i can compare . Before was between 10.5 and 12 bar .
Thanks .
