Because I had a low compression reading in number 2 cylinder when I did compression tests chasing a rough idle on my 2006 3.0, i got a bore scope and took a look a the cylinders today to see if I had a burnt valve. Fortunately, I don't. I was very impressed with the fact that all of the cylinders have all of their original cross hatching. At 295,000 miles! I found a few lines in the cylinder walls of a couple cylinders, but nothing that looks radical. I'm thinking I have stuck rings in 2 maybe. Going to try giving the engine a ring soak and see if that helps bring up the compression. I took some pics of the cylinders.
