plz help what is the problem.....

Don't start the motor anymore. The more you run it the more you break it. If it sounds like that video then you might have spun a bearing. Or maybe a piston is on it's way to the pearly gates. The way you wrote you post it alsmost sounds like you are saying it was fine before you changed the oil last week. If it was fine and now it's not, it's either a coincidence or that oil change was a doomed one.

So you changed the oil and used mobil1 and the noise showed up? To me it sounds more like a TCT gone bad. I beleive there was a thread about mobil1 causing tct's to bite the dust, ill see if i can find it for you. Also, do as the previous poster said and do not start the car anymore.

Have you checked your oil level since the oil change?

How long has the Vortech been on it?

I don't think that sound in the video is the TCT at all. I've been wrong before but def sounds like a big $$$ problem.

Def not the Tct something more serious. Not exactly sure though possibly scuffed bore.
