Help please, hole in the head?

  1. #1
    Hiya, new to this forum and I've got an issue I can't work out, changed the engine on a vts and the head is slightly different to the old engine. This one has a 2 bolt hole in that has pressure coming through when started. Sounds like an exhaust blow. What is supposed to go into this? It's not the hole in the cam cover which I know is the breather back to intake. It's at the front right hand side ofnthr engine above the gearbox.



    Hope the photo works!

    Thanks in advance

    It's air pump for emissions, it's pumping air to the exhaust for short time after starting engine to meet emissions and prevent 2nd lambda after cat to not show EML light. Just plumb it, I used 10p coin ;-)

    Brilliant thanks! I've made a little plate to cover it now and sealed it.
    I was worried incase I blocked it and caused back pressure somewhere and did damage.
    Ready for an mot now!
    Thanks again
