    Does anyone know the measurment to drill the O2 sensor in the exhaust manifold?

    I saw pictures here on GH and it looks like there is not much room for error there, Does any one know a center line to centerline measurement?

    The ones I have done I used layout die and a endmill plunging enough to mark it moving around til I had the even distance around the radius. Lock the table down drill and tap.

    all I can say is you better get the threads perfect...otherwise they will strip and your sensor will pop out. In retrospect I would've had a machine shop do mine. Heli coil replace kit is $100 bucks.
