Coolant Plug Leak On Dart Head Help
I have a small coolant leak coming from the plug toward the back, passenger side, of my newly installed Dart head. It is the plug that came off the original head. I noticed that the plug seemed to sit flush against the original head when installed. But on the Dart head, it has about 1/4" of space between the head surface and the head of the plug, after tightening. I called Dart and they said it should be OK that way because its a pipe thread (tapered). I took the plug out, put a load of thread sealant (ARP) back on it and tightened it as much as I could, it still leaks. I was thinking of getting a brass plug to try. Anyone have any other ideas? Does anyone know the thread size and pitch for that plug? Thanks

Found out that the thread is an M12x1.5 (not pipe thread). Don't think they make that in a brass plug. I'm going to try an O-ring and some silicone on the original plug. Thanks for the help.
