I just recently had the top half of the motor overhauled due to blown heads. Ever since then I had a oil leak that started and now it is pretty bad. We took it in to get an estimate and mechanic said they really didnt know where the leak was coming from until he pull the front cover off. But he said it looks like it is leaking from the front main seal. So he was gonna replace all three seals but I can't afford it so gonna try and do it myself with a help of a friend. Hard to tell where the oil coming from too becuz the oil is all over the place. No I don't have a FMS.
