Had someone bring me this car. The owner has no history on this car, he just bought it not running. Looks like it hasn't run for many years. I changed the oil and finally got it to run. It runs but don't sound good at all. I think it has a rod knock. Can't hear it at idle but you can when you give it gas. Looks like someone did a head gasket job on it. Has head studs and a multi layer gasket. Someone probably popped it good and filled the crank case with antifreeze.

Anyways, here's the video. Not much to look at but I think the audio does what it needs to.

Ignore the bad exhaust leak at idle.
 
Sounds like a rod knock. Either that or the crank is thrusting around and counterweights are hitting stuff
 
I dont really see the crank moving back and forth, but it probably dont need to move much. I think it is toast.
 
I had a cracked flywheel once that sounded just like that only under load. Worth looking into at least. But more than likely a rod knock.
 
I think if you keep reving it like that, the problem will show itself!.......I vote rod knock!
 
Ooh Me!!! Ooh Me!!!! (with hand raised)...... it's a diesel?

:p

sounds like a rod to me.... better tear it down and fix it before it spins a bearing.....if it hadn't already....
