I have a leak coming from the timing chain tensioner plug. I have had recommendations from placing a copper seal in there to replacing the tensioner. Not having done this before, if I remove the plug cap, will I screw up anything on the tensioner itself? Secondly, any suggestions on the sealing of this leak?
