I have an oil leak and can't tell if it's specifically coming from an axle seal or rear seal. Both seals were just changed when I had the clutch done. Engine and tranny both have Redline oil which look similar. Think I'll try some dye in the engine since it's due for an oil change and I can do that shortly after the testing. Has anyone used the Tracerline "All in One" TP 3400-0601 UV dye for finding oil leaks? Any bad after effects? Thanks for any replies.
