I am not sure the Arruza gaskets will handle this. Nor the Cometics. It appears that the return home in the block is drilled incorrectly. You can see where the embossing on gasket barely surrounded the hole. It look like there embossing actually squished into the hole allowing oil seep around. Its about 1/16" to 1/8" off. I did add sealant but must not have been enough. I am not sure what options I have now. Anything requiring drilling will leave possibility of chips in the pan. External return in that corner? Another gasket with even more sealant? Looking for additional ideas. I am not happy with this adventure.
