I am using townace cr 27 with 2c enging without turbo. I noticed around 750ml of oil reduction per 1000km when oil level got topup. But oil level was reached certain level between maximum and lower level it is hard to obtain reduction only very small reduction is there. And tiny white smoke can be noticed on the tube which is used to check oil level. But no white smoke in silencer. When it strats in morning it will crank several times to start. But when it heats 3 times it starts normaly. I dont know that problem is due to fault engine or glow plugs.
So i request a advice, do i need to overhaul the engine and is it good time. Or can i keep runing further?
