Hi todd,

        I don’t think it is cracked as with the other caps it would hold pressure after a trip for 5 or more days until I would check it.  the Expansion tank would then fill when I opened the cap.  now the tank fills when cool and there is equal pressure.

Also, when stopped for long or short times the pressure remained high in the tank and air was in the expansion tank.  Over flow seemed to not change.  I changed the blue cap several times.  Just before leaving and returning from West River Westies I put on a known good original VW cap gifted from a friend who had just found another new original.
