1999 Triton 5.4 V8 "Knock"
I hope someone can help with this issue. Here's a link to the video:
This started when I was on a long trip. Made it about 400 miles, stopped for a break, and it was doing this when I started it up again. I had the truck shipped home rather than driving it back. In my ignorance I've been running 10W40. The truck only has 131k miles. I've been told everything from a stuck lifter to new motor and back. Does anyone have any idea what is doing this?
I live in El Paso and so far nowhere I have taken it will do any sort of diagnosing the problem; all they tell me is that I need a new motor. A motor is $3000 on the cheap side and I don't know enough about this truck to be buying engines. I've also heard this could be the timing chain guide, a stuck lifter, or any number of other things.

Sounds like the timing chain got some slack and is hitting the guide I'd say time for a rebuild could be a lifter as well pull it apart and look buddy in sure there's a few forum guys that know these trucks in el paso that can lend a hand one weekend
Put your ear to the motor where does the noise sound like its coming from that's the give away

Assuming you haven't ran it to hard/long, you may be able to salvage the block. I would take the oil pan off and check for metal/iron shavings(this will pretty much tell you it's a rod). Depending on what internals are messed up, you may save 500 or so bucks rebuilding it. However, before I pay 1500-2000 on heads, crank, bearings, etc and labor. I would just purchase a new one and drop it in. Less pain and worries.

Thanks for the replies.
Tomorrow I'll drop the oil pan but yeah from everything I've heard it needs a new motor. Unfortunately I can't sink that kind of money into it right now. I know next to nothing about engines and every mechanic around here wants me to supply the new motor and charge a minimum of $1000 for labor.
