fitting janspeed 4-2-1 mani

  1. #1
    gonna be re-fitting my manifold today after having to change it back for the mot (bastards) and i seem to have misplaced the oil return plug nut

    can anyone remember what size the hole generally is? I know they have to be tapped out to begin with but mine had already been done when I bought the car..are there any common sizes that are used? around an 8mm or 10mm roughly?


    cheers

    it does look around a 10mm but i didnt wanna buy the wrong nut bolt :/ might be worth just buying a bag of bolts...also i dont know if this is a common problem but last time the manifold was on it was knocking against my gearbox quite badly..will also need a bolt and some washers i think lol
