That link is a big help, recently bought a sled and don't know if the power valves have been cleaned (only 1800 miles but still) so i'll probably tackle it. About how long does it take for a mechanically inclined person?Quinlan said:By the sounds of it you've never had your PV's apart. Check out THIS pic I uploaded awhile ago. If you can't read it, click "view original" to blow it up. That will give you a good idea of how it comes apart, and what to expect. After the valves are you, you will see how to take it apart further to replace the gaskets, if need be. From what I recall, there are no paper gaskets, only metal ones.
