How do you fix an oil leak on a truck?

the spot where it's leaking is by the oil panHow do you fix an oil leak on a truck?
Well, the leak might be there, or it might be somewhere else. What you should do is go to an auto parts store, and ask for some flourescent leak detector. This is an oil with a flourescent additive. You put it in, and then use a black light to see where it first appears. It's easy to use on a vehicle that has leaked oil, because you can ignore all the old oil. The leakage shows up very specifically. You can get a black light bulb at some hardware stores. You don't have to change the oil afterwards, as the flourescent dye has no effect on the engine. There is some investment in the light, but maybe you can borrow one from a hippie friend who uses it to light up his posters. I would put the truck up on stands, put some cardboard under it, and then wait until dark, add the dye, and fire up the engine. Then lay underneath with the black light and watch what happens for 5-10 minutes. Once you have determined the ACTUAL leak location, you can decide what to do to fix it. You want to look in a good manual for the fix, because it may be necessary to drop the pan, but not always, and you don't want to do more work than you need to.
