Good, I have an Optra Motor Desing 2008, I bought it with the engine, ado and I made the machine, at 4 months I started throwing some smoke where the motor oil measure goes. And after about 9 months he started consuming oil, at 12 months he already bounced smoke for the exhaust, total that the machine did again, changed mechanics and rectification workshop. But it turns out that just a month ago and it is already throwing some smoke by which oil is measured again, and I do not know what it is finally, since the camera was rectified, valvul; new, new guides, new caps, the engine is directed and standar, new rings mahled brand. What is this time that it gives mineral oil since with the problems of Venezuela there is no semi -intentic. Please help me.
