Comments: To: James V <tornadored@EARTHLINK.NET>

This reminds me of when my '65 Beetle convertible sucked #3 exhaust valve
years ago.  It broke the top out of #3 piston and pieces of it ended up
embedded in the combustion chambers of #s 1, 2, and 4.

It sure sounds like it's time to pull the heads and see what has happened.
