I take my car to get it's oil change since I'm lazy... The guy tells me my rear main seal is leaking!!! Is that possible, I only got like 12k miles on my car!!!! I know I got many many parts but wow!!!! I barely have any miles on it!!!! He also said my custom exhaust prevented him from checking my gear oil in the back, He's gotta be on crack cause that's stock going over the axel!!! ugh... I dunno maybe I let my real mechanic look at it!
