Pressure relief ball

[Chris KC]

Steve, others who can't see your engine and don't know or recall what you have already done could help you better if you listed up methodically what you have already checked in every part of the system. It's easier to spot something missing or incorrect in a list than to pull fresh ideas out of the ether (which will end up going around in circles). This thread already runs to 7 pages & I for one have forgotten what was said on page 1 by the time I get to page 4...
