Yeah, this car was completely neglected by the previous owner unfortunately. On top of the transmission issues it had at first everything was SO dirty and it took a very long time to get the exterior looking as it does now. Funny thing is the last time it was washed was right after the winter to get all of salt dust off and it was fairly dusty again from the summer driving. Along with a dirty Mass Air Flow sensor causing a check engine light to be on it was in need of an injector cleaning and full tune up. After doing all of these things it was much better but still a few things that I plan on doing to keep it well. Getting the oil done soon and Mobil 1 is high up on the list
Sorry to hear about the possible seep at the back of your engine there. Hopefully it does not get worse anytime soon because that would be such a pain.
