Getting ready next weekend(hopefully if everything arrives) doing a TBwater pump etc. Buying a kit from blauparts. It comes with front camshaft seals. How do you change them? BTW it is a 2004 GLX sedan with a V6
Hope you have cam lock tool and crank lock tool, and a good repair manual like a bentleys, must have for this job , if you are lifting or pulling cams to install seals I would install new cam chain tensioner wear pads, the lower ones are known to fail( and you can't visually inspected unless you pull it out because it's buried in the cylinder head) with high miles, some members had them last long time others not so much , they are cheap and easy to install.
I am with GLInick on this, if not leaking don't replace them unless you have to remove them for another reason.
You are much more likely to cause problems, one guy replaced his about 4 times before he got one to seal.
