So I have a leak from both the front and rear head. Top just under the removable fins. I have a terrible tapping when idling and know I am way over due for a valve adjustment. I'm wondering if anyone can help out out where I may be leaking and what may be involved in fixing it. And do you think bad valve clearance could have contributed. The leak is fairly slow. By the end of a week to and from work it's about half as bad as in the pictures. First picture is front jug with thr readiator removed. Second is rear jug from the left side. Thanks for your help all. Have a great day.
