This adapter mounts to the block and extends off at a right angle to the normal oil filter location. Theres a small leak(drip) where the adapter mounts to the block. how does this adapter mount to the block? I'm assuming an oil ring leak between the block and adapter, but I don't see any bolts holding the adapter. There are 2 pipe plugs in the adapter.

There are several engines available for your truck but the adapter seal will leak, to replace it remove the oil filter and a bolt goes up into the engine block that secures the oil cooler to the block.Takes less than an hour to replace on the V8 5.7L engine.
