Problem with my kia rio

Hello everyone and in the first place congratulations x the website ^^ is very useful .... even Acer a pretty strong noise in the capo ..... stop the car and when I opened my baps I discovered that I had metal chips flying x the entire left side of the engine ... where the distribution strap goes ..... fixing well locate that one of the poleitas through which the belt passes strangely and there I did not turn it on again, in case it helps you to try to help me the car began to release "smoke" I say smoke because I really do not know what it was for sure, I can assume that oil was no longer that it was white like vaporization ... I am something distressed thinking that it can be something serious and I dare not move it and that I do not know if this poleeita belongs to the spine It is noteworthy that the car worked correctly and I did not stop x what I am a trankilo of I am not longing out the distribution, I would come from pearls if someone has an exploded manual or a workshop manual to be able to point to you more explicitly which of the poeitas is. I greet and I wait for your answers many and greetings.
PS: I think this is the right thread to my doubt if it is not so, I apologize and please move it to the right place but without throwing it into the garbage can. Thank you

Look your problem could be relatively serious if you keep walking, the important thing is that you tell us that pulley is the one that rotates irregularly because it is the crankshaft and it is deschaved you have to make a very precise repair, Czech well that Pulley is and Tell us to be able to guide you but try not to make the vehicle walk.
