[Vwdiesel] Leaky Plastic Water Outlet at Head on 91 Ecodiesel.

[James Hansen]

No Will, just straightforward as you anticipate.  You may have overtightened
the old one a bit, which deforms the housing.  You do have to be cool on the
torque on the plastic coolant outlet, but they do warp from age and was
probably due to fail anyway, which was why it was leaking in the first
place. Orings don't fix the housing being warped.  New housing and new oring
should be all good to go.
