I agree it sounds like the bottom end (rod bearings). Bad news: engine needs rebuilt.

Good news: rebuilds are not too expensive for these engines. Probably $1600-2000 if you find the right shop. Or you might find a used engine and have someone swap it in. Sorry about your luck, hope it works out.

Could also be the harmonic ballancer. I have heard 2 different rivs make awful knock sound when the balancer fails.
Take a look/feel at it and see if the rubber has cracked around the center. also look for it to wobble when the car is running.
Mine failed at about 130k and so did a friends 97 riv.

Check the harmonic balancer. If it's a bearing definitely look for a used motor. Can be a LOT cheaper than a rebuild and have a lot of life left in it if you find a lower mile engine.

Rod knock means the a connecting rod bearing is worn, makes the rod loose on the crank shaft. Lack of oil or a lot of stress will cause this.

Be careful paying unless you know what's wrong before they start. Make sure they quote you first.

Just a word of caution: When the balancer went one my old lesabre (3800 engine) I took it to 3 shops that all said rod bearings. It turned out to be the balancer though.

Yours does sound like the bearing though, have a listen in my videos:

bad balancer:


series I knock (fast forward to 2:20)


Series II knock (fast forward to 4:45)

I bought that one from someone who let it rot in the woods for a few years. The easiest way to clean it was a new engine lol
