Finally found out the cause of the leaking. It is a machining problem, two cote are wrong. The base oring is to small, because the the groove in chimney is too small, who is supposed to cover the oring. Then thank is not seal, does not seal to hold internal pressure, and then start leaking like hell... Whit the topcap oring seam story... If you d'ont have a CNC to made the groove for oring bigger, and the put the bigger and decent oring... il will leak... no mather what kind of setup, much cotton, etc. I change the two oring with a biggers one, and i tight them. But i c'ant enlarge the groove... Now it is leak a little, suportable...
Bad... bad chinesse CNC... a little atention and is was perfect...
