I bought my 1994 yj about a month ago. When I bought I saw that it had an oil leak but the guy said he had just had it fixed. I got it home and sure enough the oil leak had not been fixed. I could not tell exactly where it was coming from. So cleaned engine and compartment with purple power and got it all cleaned up. Noticed it was leaking from the valve cover so pulled it off put on new gasket (from autozone felpro). Still leaked around valve cover so pulled it off and put some red rtv on it no leak after 2weeks from valve cover. But still have an oil leak only not as bad. I think it may either be coming from the oil pan or the timing chain cover. Both have oil on them.Some told me not to worry about it because that age always leaks but I hate oil on my driveway. So my question is should I replace both oil pan and timing chain cover gasket at the same time or one then the other. Oil pan looks easy to get to just remove starter but how hard is the timing chain cover to remove and change. I have the 2.5 L 4 speed.
