I have a 2006 F150 4.6L RWD I'm getting a really bad knocking/rattling from the engine paired with white smoke from the exhaust. Does anyone have any ideas about what it might be from and how I should go about repairing it?

The video below on the issue

 

How does the oil on the dipstick look? That sounds terrible, and expensive.

What's the history? Were you doing a smokey burnout?

 

I haven't checked the dipstick in a while its been sitting for a couple of months now and yea I've done a couple of burnouts and donuts but the problem started way after them

 

Might just be low on oil. The "white smoke" looks like typical cold morning water vapor.

Check the oil. It will tell you something. Oil is important. Very.
