to make a short story even shorter i decided i wanted to change my pcv valve out so i buy one install it and manage to crack the plenum because i screwed it in too much. its a hair line crack spanning about an inch down the area the valve is threadded i know the car runs fine but what should i do for a quick fix i hear jb weld would be good so far i have gorilla glue as a temporary. any suggestions i have 163,000 miles on the car so im not spending more then i have to. and i know im kicking myself in the ass for not stopping when the wrench was getting hard to turn.
