Attention: TDR Forum Junkies hey guys on my 99 i changed the oil drain plug from the stock one to the Heavy duty oil plug about a year ago. everything has been perfect untill last oil change i noticed that there was an oil spot in the drive way so i got under to look and sure enough the oil was coming from the plug area. so i ordered a new gasket from cummins and changed the oil again (only 100 miles on the oil) and replaced the gasket last night. this morning i get up to go check and there again is an oil spot on the driveway about the size of a CD. 
i have made sure that i torqued it to the 40 ft. lb and still leaks. any ideas?? it only leaks over night when everything cools down. and oil changes every 100-to-200 miles is getting old FAST!!! i know i dont have to change the oil but it's hard to remove one plug and screw my old one in place before i loose all the oil in the pan.
