I posted a message the other day regarding an oil leak in my son's '86 LX with the 3.8. We found out that it's leaking from the oil pan and rear main. Also, the PCV is plugged and there's gunk internally causing internal pressure which is forcing oil up into the air cleaner. I'm having the engine cleaned out as best it can be but I can't afford to have the other leaks fixed. Is there anything I can pour into the engine to seal up the other leaks or should I just keep checking the oil level and filling it as needed? It's a nice little car so I would like to keep it running. As I said before, I'm not a Ford guy so I need all the help I can get from all you Mustang experts. Thanks.
