I'm rebuilding a new engine and i can't for the life of me remove this piece from the old block, a short rubber pipe goes from the oil filter base to it? It screws into the block and has a nipple for the pipe to slide over? What do i ask for when I call Subaru for the part? It's something todo with the stock oil cooling system?

 

Use a 2 foot bar and a 24mm socket to remove it.

Its a water supply/outlet from the block to the water pump.

 

yea i figured its todo with the stock cooler, and it dawned on me that it might be left threaded. in the subaru manual its simply referred to as a "plug". Anyhow called subaru. they got a new one for 3.5GBP converted from my currency. Just gonna get a new one for my new shiny Axis EJ25
