It's a single bolt camshaft...here's another interesting nugget of info that may or may not have any impact on this. On the way up to Canada I hit a giant chunk of concrete in Michigan. Perhaps it caused a small oil leak that lead to this? |
I'm sorry that your motor blew up. I got money on the culprit being the single bolt cam set up. I bet it sheared the little metal peg that keeps the cam sprocket from spinning on the cam. I have seen this before a few times and is the reason I will not install a single bolt cam in any car I work on. I swap them all to a 3 bolt sprocket.
Edit: Just looked at the pics and it looks like MasterZ is right about the lifter roller going out. You can see the cam lobe looks all chewed up. Can you take a pic of the bottom of the lifter?
