no, it's not burning any oil that I know of. I don't think that would have happened in less than 2-3 minutes time though...I hope not anyhow...

 

Would be real bad if it happenend in 2-3 min, I do remember your post on this issue and more I think about it does sound like an injector(or two) that went haywire, after hearing more info from your problem. Hope it works out for you, some times these problems turn out to not be as bad as they seem.
