I agree with you, the cylinder does not look bad, it is only polished, before that the car had strength, that is, it did not stay on a rise for example. What happens is that I do not have enough money to buy the rings and burnish (I do not know if it says that) shirts, in my country it is very expensive that. With the cylinder so the risk of starting to pass oil?
It is difficult to say that you can go without seeing it. As I put before, there are several factors to review before drawing conclusions. Deformity, light of rings, stripes, etc. If it was good before, it probably will. Keep in mind that in repairing any leaks that may exist for the valves, you will increase the compression in the cylinders. So oil consumption may appear since the compression that was previously lost due to poor valve closure, will now try to escape through the hoops.
If you can not economically afford the full repair, there is no other way to prove it. Luck!!
