I know its not going to be easy to make a leak-free car, but it bothers me. Least is the oil leak, it just leaks a little, probably from the drain plug. Last time I changed the oil, I did replace the plastic washer. Second is the transmission. I'm pretty sure its just leaking around the pan, slight possibility that there may be another leak (small) near the yoke. Last, and most noticable is the rear end leak. I replaced the center section about a year ago and it leaked a little, but its just getting worst (or mabye the same, but I got to fix it), its a new assembly so I dont want it to run out of fluid. I can't really identify where the leak(s) is coming from, I've retighted all the bolts, I think it is also leaking where the driveshaft hooks up. What should I do?
