I lucked out! Well actually I had installed a FilterMag on the
oil filter a while ago and it caught most of the stuff. I didn't hear the lifter noise over the exhaust noise until I was about 1/2 a mile from home. The FilterMag is cheap protection. The filter was pretty heavy when I took it off. Keith said that there wasn't any scoring. A 5.4 DOHC would be far less grief, but then I couldn't say "it's a 427 side oiler". It's cost a lot of money to say that!
