Hi all, I am new to this forum but I seek your knowledge! I have an a10 road rocket that I use in the warmer months. Last week I decided the time was right to wake the rocket from her winter hibernation, I went through the usual routine of draining the oil out and putting in some fresh petrol, ten minutes later she was running perfectly and all was well, or so I thought? Three day light use and I noticed an oil leak from around the back of the engine, no surprise I thought, but on further investigation I found that the oil was In fact leaking out the bottom of the magneto? I have now removed the mag and it was filled with oil, I'm not sure what could of caused this, the mag seal is fine, the only thing I can think of is whether pressure has built up in the crank case? The breather end float seems correct as I fitted a new cork shim a couple of years ago, I did notice that the oil pressure release valve was very loose, I have never heard of this problem before and so am putting the question our there, any ideas would be greatfully received, Tom
