has oil leak.
any common sources to look for?

Answer
Hello Robert, welcome to my expert page.
The most common sources are the valve cover gasket and the distributor o-ring and sometimes the rear engine mainseal, do the valve cover gasket and dist o-ring first and see if it eliminates all or most of the leak.
