[Vwdiesel] Coolant Leak at Cylinder Head Flange-Day 2

[Shawn Wright]

Part # 068121145K for the flange. 037121687 for the 'sealing washer', 
which appears to be an o-ring of size 36x3.15mm. I think most now use a 
flat gasket - the full gasket set for my TD came with one. Or just use RTV.
This is a very common flange, used on many diesel engines, so it should 
be easy to find - for example my '85 Jetta uses the same one. The gas 
version would also fit, but lacks the coolant sensor hole.
