Last night, I went to Autozone and picked up a can of the Right Stuff. I couldn't find the three-in-one magnetic claw with light tool there (its apparently a special-order item) so I bought a
Flexible pickup tool with light. I was a bit concerned that the tip might be too wide. However, I gave it a quick try this morning and it fit properly and went in quite deep. I could feel it bending as it was pushed further. I did try all four opening and unfortunately nothing was found (or, at least nothing came back attached to the magnetic tip).
That's two bolts now that have gone the way of the Bermuda Triangle in my truck. Btw, what are those openings at the top of the heads called? Intake ports?
