[s-cars] How much are the RS2 manifolds going for now?

[George Grubr]

this crack I have on all three but I also have cracks between each cylinder
piping, in the narrow part as well - you can see through it. I think I send
pictures of to Igor long time ago when we thought about welding it but there
is no way. This is with RS2 turbo and Lehmann head, running at least 60% of
time 5k+ RPMS so the stress is there.  

If you have the cover under the engine it would have to be rather deep
puddle to get the water on the manifold .....

FWIW, pulled the OEM K24 off the Avant apart the other day.  @100,000 on the
turbo at the time it was pulled off the car.  There are two visible
significant cracks in the internal hot side scroll that go "side to side"
through the narrow part, but are not otherwise externally apparent.  No
abuse AFAIK by the prior owner (@ 80K), I think they can .... just crack,
though I'd suspect a really good thermal shock - drive through a really deep
puddle etc. if enough water somehow found its way up, or down to a red hot
exhaust manifold / turbine scroll could do it.
These two crack OTOH, seem to be internal however.  At least any
disintegrating parts, if the scroll failed, ought to be on their way away
from, and out of the engine.
