Ok so last night after a decently hard signal pull, I noticed this noise. At first I thought it was coming from the top end, but then I took the second vid and it worse from underneath. I put in a quart of ATF and some seafoam to see if maybe it was just a collasped lifter or clogged oil port but after 15 minutes of driving it started to misfire and throw a code, and finally died right next to my house.. Won't start.

Rod knock? Or valve issue?

 

Now that we have the second video it sounds like a rod knock or spun bearing. Sorry to hear man. I had to replace the engine in our green wagon with the same problem.

Here is a spun bearing

 

Update:

Runs now. It was one of the positive wires coming off the battery, it was loose :l

But the knock is still there. I will be pulling the pan this weekend, or maybe just the whole darn thing
