Because of an upcoming trip I've planned on my '02, (that AND I was tired of listening to the sewing-machine type clicking while at high-idle), I decided to upgrade the cam tensioner with the one from rubber chicken racing. The job was very straight forward but was even easier because of a new tool purchase (needed for a different automotive project): crow's feet.
I bought a set a little over a month ago because they were the ONLY way I could remove a remote oil filter line on my old Toyota Land Cruiser without removing the header and intake manifold. The set cost me ~$75 from Sears which is pricey, but they did accidentally include two extra pieces in the set. Bonus.
Anyway, the cam tensioner change only took me ~45min start to finish (all tool roundup time included) and I did not have to take off the throttle body. I loosened the tensioner with the crow's foot, then I could unscrew and screw in the tensioners by hand (most of the way). Slightly tedious but not too bad. Pictures below:
Crow's foot. I needed a 17mm to remove the tensioner and 15 to install the new (if I recall correctly).

Would it be worth it to buy these things for just this? No, not unless you have a lot of disposable income. However, they are really great for the two jobs I've used them for; I can't believe I've been going for all these years without a set!
