Do these studs go into a water jacket? How can I fix this?

This Aulro app is not showing me your image. Could the leak be originating from the Welch plug that is somewhere along the mid point of the manifold?

The leak is right at one end, the rear of the motor on the last stud. I guess it could be coming from the middle, but I cannot see any sign of it leaking anywhere else?....

Take the turbo heat shield and the exhaust manifold shield off and check the welch plug between cylinders 3&4. It's a screw in welch plug with an Allen key drive and is prone to loosening over time and leaking. Mine's done it. Unfortunately you can't tighten it up due to no access for the Allen wrench .... Have to remove the exhaust manifold to gain access. If it is that, as a temporary fix I was able to use a drift and working from overhead, drive the Allen welch plug around another 3/4 of a turn .... All but stopped the leak. Kev.. Sent from my iPad using Braille
