Hi all, my valve has started pissing water again.

This is the second in 1 year, i have been using the GSF one and think the quality is not to good , can a vw original still be obtained ? i have a german converted whitestar 1z 1.9 tdi and the temp gauge never goes over half way so i don't think extreme heat is making it fail. Has anyone else experianced this.
Thanks stephen
