I pulled the lifter from #5 so far just to see if it was marred in any way since the pushrod literally snapped in half. Lifter looked fine to my surprise.
This is a real odd deal and we are trying to get to the bottom of what may have caused this. The pushrods are 5/16 diameter so its not like they were pinners. I do expect to see some bent valves but I think Vince thinks I may have dodged a bullet. We'll see in the morning.
Tomorrow morning we will pull motor. Then we will pull heads off and take a peek. Once the heads have been pulled and inspected I'm going to take a look at the oil pump. Something had to have jammed somewhere in order for the chain to snap. I have never seen a timing chain fail before so I would really like to get to the bottom of this.
The timing chain is a PBM double roller
