Received the news today that two valves failed, one and four, which is 1 in each head, and it was the rocker arms that were the failure points. That is good news because the failed parts were contained under the valve covers and did not damage the cylindler, piston, or valve side of the head. A machine shop will now check and repair the failed or worn parts. It is difficult to sit on the side line and watch someone else turn the wrenches.
In the mean time, I am enjoying driving the PT Cruiser and rowing my own gears.
