I am thinking about replacing the cam chain tensioners to the spring loaded style on my car as a bit of preventative maintenance. I have a 97 boxster with 120K and as far as I know it's got the original ones.

When it's cold it makes a pretty noticeable rattle on start up, especially if it's under 40 degrees outside. In the summer, it only does it when it has been sitting for a few days. I did some searching on the forum, asked my mechanic and it sounds like a normal thing, but I really hate it and I am afraid that it will will the motor.

I looked at the instructions on Pelican Parts and it looks pretty straight forward. The only thing that I don't have is the P253 tool to lock the cams. Do I need to lock the cams to replace the external tensioners? Has any one DIY'ed this one and have some tips to share?

Thanks,

Reed
