I have been using the adapter for a couple years and everything if doing fine,I now have a working temp gauge and it will not go over 180. I did have a aluminum valve cover with a cap and oil would seep out of it now and then but I have since put on a 216 valve cover with no cap and even with the vents in it I have not gotten any oil on the valve cover out of the vents,the 216 valve covers cam be made to work on the 55-62 motors (I have a 57) and make sure you get the matching road draft tube so you have a place to put in the oil. I have been trying to make the 235 look as much like a 216 as possible.
