^That makes it over pressurize and vent from the noid^
Noids rarely go bad, Unless you put a grip screw threw it. The board and noid are the parts that cant be repaired when they **** the bed. They also happen to be the most costly to replace (I got a new board for mine for $125 from trade my gun @ cup last year). You must have put the wrong O-rings on. Or you board is not supplying proper power due to a short or something. Try another board from a marker you know is good. 08s are pretty popular so you should be able to find someone local and try there board.
