A brief trip today, but with a high grin factor. The replacement PCV valve for my +4 arrived and was installed in a jiffy. We had a dry moment with fewer potholes and ruts on the 1-mile trip from my house to pavement, so off I went for a test drive. It was only about 10 miles, round trip. I took every opportunity to row through the gears at WOT to redline. I'm pleased to say there was nary a misfire heard. Funny how actually advancing the timing as the revs increase improves engine performance, innit?
