Q: Oil Leak on 2003 Ford Ranger

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
I had an oil leak and the dealer replaced the oil pan gasket at a cost of $400.00. The problem remained and now the dealer says the rear main seal needs replaced for another $400.00. Shouldn't the dealer have know that the oil pan gasket was not the problem?

Oil leaks can be a very compicated problem to resolve.
Did the dealer use leak detection dye in the oil to determine exactly where the leak was coming from? Did they throughly clean the oil pan and related areas when they were done? If you don't know the answer to either of these, you need to find out.
One of two things may be possible. Either another leak has developed since the pan gasket was replaced (as the dealer has implied), or, what you think may still be a leak is actually residual oil still dripping because the pan and related oily areas weren't cleaned after the work was done.
I don't know about the leak detection dye, but I doubt it since the diagnosis and repair was done in about 2 1/2 hours. The pan and areas were cleaned after the repair according to the service manager. It has only been 1 week since the pan gasket was replaced so I doubt it is a new leak.
