Anyone know what the most common places are for oil to leak on a 1994 Altima? I've got some dampness all the way around the valve cover gasket, but I'm not sure if that would account for the amount of oil missing since my last change around August 1st -- it's down a little less than 1/3 of the way from the top of the hashed area on the stick. Just wondering if there's somewhere else I should look for signs of a leak.
Thanks.
