Lets hope this is true.

BP engineers Thursday stopped oil flowing into the Gulf of Mexico for the first time since April as they shut all valves on a new cap placed on top of a fractured wellhead, a BP official said. "It is good to see no oil going into the Gulf of Mexico," said senior vice president Kent Wells, but he cautioned: "We are just starting the test." He said the oil flow stopped as the last of three valves on a huge capping stack was shut at around 2:25 (1925 GMT) Thursday, but engineers were keeping a close eye on the operation to see whether any oil began leaking again.Link
