Recently purchased retired PD P71

I found a pretty bad oil leak; it right above the oil filter, there\\'s a \\"housing\\" that the oil filter attaches to, this \\"housing\\" bolts to the block. Any suggestions on a \\"replacement\\" part, or could it be just a gasket?

Thanks!

It's probably the gasket for the "oil filter adapter" which goes between the block and the filter.
Since it's a P71, make sure to get the gasket for "with oil cooler"

Thanks, you were correct.
