This is a 9.3 turbo had a small oil leak only present at above 1500 rpm at the bottom rear of the cylinder head or so it appeared. Removed head to replace the gasket and discovered the leak is lower than first thought by a few inches and it seems to be a seam of some sort it is very close to the oil passage my question is this a block that comes apart in mutiple peaces or is this a repairable part of the block or is the seam I see a casting mark, there seems to be 2 more seams on the block each lower.
