I had the timing belt changed (10 years old in August, but only 50K miles on it) and a leaking oil pump replaced. The mechanic who worked on it showed me pics on his phone that he took, so I asked him to text them to me, & he obliged. He was surprised that the top end was as clean as it was. There is only one shot under the valve cover, and it wasn't straight down, but you can still see that it is fairly clean. I also can see the pic where he took off the timing belt. The last two, though, I can't figure out what they are. I'm not a mechanic, but I went to parts.toyota.com but still couldn't figure out what they are. I know the folks here can edumacate me on those two.
