If you can do the work yourself, you'd probably spend less than $30 U.S. if you replaced the piston and tappet. Removing the nozzle o-ring costs nothing. If you have to pay a tech to do it, well, that's up to him!

Freedom is the wolves limping away while the sheep reloads.
Never confuse freedom with democracy.
