Blown wrist pin?

Postby Trevorw503 » Fri May 12, 2017 1:07 pm

So I was just driving down the highway at 60 when this noise starts happening out of nowhere. No initial tick that was quite. We're not too sure what it is since it is so loud. It doesn't sound that loud on camera, but in person it sounds like someone hammering the top of the block. And since there was no initial tick indicating rod knock, and oil in the engine, we think it's a blown wrist pin. Any ideas?
