I am about to do a valve adjustment on my 1997 Outback 2.5L and a few other Outbacks 2.5L of friends at my work. I have not decided to get the shim replacer tool part number 498187200 but if it makes the job go much easier I might get it, this tool replaced the old one (498187100). On a "The End Wrench" document it showed how to use the old tool (498187100) and it was straight forward on how to use it. It appears to me that this new tool (498187200) is to big, there is very little room in between the cam, the head and the valve to get this tool in there. Maybe I'm just having a brain fart on this one, so does anybody have pictures of this tool in use or know of some pictures on-line of it being used. Thanks
