Oil Cooler Adapter Oil Leak
I have been struggling with an oil leak around the adapter that bolts to the block where the oil filter was mounted. I have a steady drip about every 1 or 2 seconds. I have removed the adapter, cleaned the gasket surfaces of the adapter and block, checked the adapter for cracks or abnormalities and having found none reassembled the adapter with a new gasket. This time I used VersaChem gasket sealant (non-hardening) on the block and adapter gasket surfaces. I torqued the adapter mounting bolts to about 15 ft-lbs. When it continued to leak I tightened the bolts a little more. Still it leaked. The gasket was originally assembled dry. After all these efforts it still leaks. The block is a BBM 427SO cast iron block. What am I missing here? This can't be rocket science! Does anybody reading this have any ideas or have you a similar experience? Below is a picture of the adapter mounted to the block with the oil cooler lines.
