hi was just wondering could someone shed some light on my oil burning problem. car doesnt smoke until i roll down hill and then throtle as i get onto the flat then you notice a big cloud of smoke, ive already ordered new stem seals as i have to change a cracked head but curious as i would rather change the rings at the same time, there is no contamination of the oil or water. car is missing due to water in no4 plug, does anyone know the torque settings for the spark plugs as i dont want to be splitting this head. i would be very grateful for any help thanks
