hi stewart,1 of the 2 e-clips they call them was missing(the first one you see when you pull off that small 2 bolt cover on right side)when i pulled the cover off the collar they call it or wheel looking part was way over to one side wedged in and the e-clip was down in that bottom rubber boot.53 cents for the e-clip and i would think the problem should be solved.,rubber boot was rough looking and previous owner had a lot of gasket sealer so i did the same for it wont leak so waiting 24 hours for it to dry before i test it out.i did notice the arm that has the 1/4" end coming out that fits right in between the collar/wheel has a groove or indentation on the right side of it,i dont know why it would but i am thinking maybe because the e-clip and collar fell off that it wasnt sitting properly and wore on one side,the local dealer said thay did not know if it was supposed to have a groove,they weremt much help just wanted to fix it themselves.$60.00 -$90.00 just to look at it and $160.00 $210.00(ouch!!) to totally clean the powervalve.what do you think about the groove on the end of the lever? looks like its 1-bolt and a 1 minute job to replace.
