Thanks GG
Made me think I certainly didn't re-install these, so the additional tape will be more than I used first time.
Not sure where else I can screw in these fittings but seeing as they are done I'm not looking really to relocate.
Though they could be separated with the pressure on the block and temp via the remote
oil flow lines that can just be seen in the shot. If I can find an in-line fitting into which I can screw the temp sensor that's worth some consideration.
If this were possible I assume it will be better to screw into the
oil line leaving the block rather than the return (cooled) flow?
But I'll give the faux earth a try first though as a simple fix.
Cheers
Steve
