The crack you are discribing is in the right side cylinder head at the top studs that hold the head in place this is very common. If the engine does have only 70 K on it then new heads would be in order

I read the info under head gasket leaks.  I have a coolant leak (84 Westy
with 70,000) which initial diagnosis by taking off air filter and seeing
coolant coming out where stud is.. is hairline fracture or rare possibility
that touquing might fix.  Does this mean I will be out a couple of thousand
of dollars?  Does it also mean that I should have other side rebuilt which
means more $?  Any advise will help?  I read the info on VW arbitration but
assume my vehicle is too old for that?
