The pressure relief valve on my G is stuck. We have tried soaking it with PB Blaster, heating the block, and tapping the block gently with a hammer. Nothing seems to get it to come loose. What are some of the tricks that some of you have tried to solve this problem? Thanks as always.

I should also say that we have tried air pressure through the oil galleys in the block.
