Blumin eck :( Air leak on keg (again)

[Baldy]

Grrr :x , Hello chaps, advice needed...

I am currently trying to brew what is my 4th brew now. The fermentation was done in an FV and then the brew syphoned into a king keg once fermentation completed along with 4oz of sugar for secondary fermentation/carbonation.

The previous two brews saw me suffering from a leaky serving tap on the king keg which i seem to have successfully sorted for this brew. Problem with this one is that even though i was very generous with the vaseline on the top cap, i can hear it leaking air from here during this last week as the pressure has built in the barrell. The king keg and brew has currently been stood for 7 days since 1st fermentation complete.

So what should i do now? Obviously i need to take the lid off and re-apply some vaseline and attempt to make it airtight?? I have been advised by my local brew shop on previous brews to open the barrell and reseal all the caps so they don't leak, and add more sugar and seal it up again to allow carbonation to happen again?

Is this the right thing to do and if so what is the amount of sugar to add again to allow carbonisation to happen??

Many thanks,
Rob :)

are you sure its comming from the cap and not the relief valve in the cap? if it is the relief valve then this is normal if the beer is over pressuring and will stop when the pressure in the barrel reaches a safe pressure. if it is definatly leeking from the cap remove it and check the condition of the o ring if the cap has been over tightend these have a tendency to disfigure or even split causing a leek path. It could also be that the relief valve is passing constantly and needs changing. In any circumstance i cannot stress the importance of not over tightening the cap (trust me i know from experience). also i wouldnt bother with more priming sugar it may spoil the taste of your brew but it should still carbonate enough anyway.

hope this helps
