I have a 1974 fj40 with f155 stock motor that has a lot of crankcase pressure and recently had side over, oil pan gasket and valve cover gasket leaks. These leaks have not all occurred at once, but once I fix one issue, drive several miles another ones happens. Is there someone with experience that could help me determine what would cause these issue ? I appreciate any help anyone could give me. Thanks in advance,
Tom
