[urq] Heat cycle brand new Dialynx manifold

[Schaible, David]

I am in the process of getting 15 10v em w/ cracks welded.  I finally
found a guy claiming to be competent in cast welding (lost the old guy
who did mine).  My welded unit has been on for 5+ years with no problems
on a WX (the incinerator).

Give a shout if anyone need one.

And they still warp like a banana when used on an MB engine.
Not only that, they are the most difficult things to fit - mainly
because 
they don't fit properly. I had one and lived with it for 3 years, 
retightening studs and replacing nuts as they loosened every couple of 
months. Junked it as soon as I was able to get my hands on an Audi unit.

Regards,

Jim Haseltine
