David

I can add a similar problem to that which you identified where there were
100 sump gaskets on the market that did not a have a hole where the oil
behind the valve could  get away resulting in the relief valve not operate
correctly.

If the valve did not 'relief' then oil pressure could rise way above the
safe reading. This could cause the pump to have to work harder and the
stain on the pump, pump shaft and cam shaft could cause damage.

Best regards
