Yes me too.
Changed out my oil pan gasket for a newer silicone one, and as that drain n=
otch had not been cut out oil pressure went through the roof. Had to drop t=
he pan again and make a notch.rg

David
I can add a similar problem to that which you identified where there were 1=
00 sump gaskets on the market that did not a have a hole where the oil behi=
nd the valve could  get away resulting in the relief valve not operate corr=
ectly.
If the valve did not 'relief' then oil pressure could rise way above the sa=
fe 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
