Subject:      How is coolant getting to exhaust???
Content-Type: TEXT/PLAIN; charset=US-ASCII

I've recently reassembled my cylinder heads for the second time in a
week and I am very sad because it is still aggressively leaking
coolant from the exhaust port near cylinder 1.  See the pain here:

http://communitybuilders.dhs.org/craigoda/vw/cylinderhead/index.html

I carefully cleaned all surfaces near the green o-ring and aluminum
compression ring.  I can't find any crack.  Though, I did not yet take
the head to a shop to be tested.  I can't figure out how coolant would
get to the exahust even if there was a crack.  there is no coolant in
the head itself right?

What would cause this much coolant to get to the exhaust?  I feel it
is a crack, but when I look at the head, it looks fine and I looked
very carefully.

Does anyone have any suggestions?

The inner round surface of the head where it mates with the cylinder
sleeve looks fine.  This last time, I even put hylomar sealant on the
green o-ring as an extra precaution.

If I stick my finger into the exhaust port of the head, it is filled with coolant.

When I took the heads off the cylinder sleeves, I had to pry it off
with wedges.  Is it possible that I warped the cylinder sleeves?
