Have not yet pulled the two block plugs for coolant.....look like maybe 3/8 pipe. Am considering making a spray nozzle that would hit any mud residue from the sides and hopefully flush better. On this old beastie, have gotten a lot of brown mud with several flushes and want to do something with these drain areas. Has anyone tried to flush with pressure on theirs.....I think a bath would be in order. thanks
