Boost leak test

How long should you be able to hold pressure for ?

I know I have a small leak in a breather hose right at the back of the engine that's ganna be a PITA to sort :rant: but it's only a small one. I can barley get it to 3 - 4 PSI or maybe the crappy compressor I'm using just aint up to it.

    Probably the crapy compressor.

     

    Its not a case of how long can it hold it for, but how much pressure. Dont do more that 5 PSI, and more than that and you will probably cause leaks. Dont forget that you are putting pressure on some things the wrong way.

     

     

    Personally I have put 5psi in it for 10 mins at a time, filling it up and the looking for the leak.

    Cheers SRRAE, it is a crap compressor (and gauge probably) but as soon as I stop pumping in it's gone within a few seconds, would that point to a MAJOR leak somwhere

    No, that's not a major leak. Think of the volume of air the engine flows at say 5000 rpm.
