did fabricate a new pipe, and with some tuning it is going UNDER the water pipe... what I like - not that terribly engineered!!
The new one is SS,, well what I found is that STOCK is built by two materials. The portion more or less in the engine bay is steel, the part parallel to waterpump etc. is braz. I was wondering as this portion had a lot of tuning marks from pliers. Now I understand why, they tuned it to fit.
My case is a bit harder to tune due to SS material. But is done. Only 2 links are missing. And a nice fit now exactly between the vale cover and the intake.
On 4907 the Stock was going OVER as the STock water pipe had very littel hight, as was sitting pretty close to the Thermosdat outlet, very close to the the heads. In my case now all new Aluminium I used silikon rubber knee hence a bit higher up.
Always interesting what you find on the car..(so far no treasury though).
