Wow now that is not a sound you want to hear... sounds a bit like an exhaust leak as well but it seems to loud to me to be lifter...I suspect rod...

That is exactly how my 99 sounded when I got it. Nothing a re-manufactured crankshaft and bearings won't fix....

Default sorry

sorry it defentily sounds like a rod. But there is possibilities it could be a cracked flywheel or the harmonic balancer might have came apart chevys are known for both and they can sound just like a knock i would check the balancer first just to be safe
