I have a 500ex kit from FST and at first I was pulling out the studs so I changed the cylindre and the studs. But know the studs are holding and the nut ( the one on the exhaust side ) is going loose. at first I only had to tight it ones every couple of weeks but know it every 10 min. I tried a diffrent nut. lock tight ...

I need help. I have a new gasket comming I don't want to blow this one up to.

all I want to do is drive this dam thing

HELP
