If it wasn't leaking when you took it into JiffyLube, it should not have leaked after the oil change. Are you certain where it is leaking from? If I had to go out on a limb, I'd say the halfwits at JiffyLube never checked the rubber gasket on the filter and the oil leak is coming from there. That is a common error among the inexperienced. Personally, I will NEVER let any af these "pit stop" type places touch my car. If I can't do my oil change, I'll take it to my mechanic to do. That doesn't cost much more and usually takes just a little longer. I will also never take my car to the automotive department of a department store like Sears, WalMart, Canadian Tire, or Zellers. I've heard too many horror stories come out of these places. A good mechanic is like a good spouse. They can take a while to find and once you do, you need to nurture the relationship. Respect what they do, their time and their talents. Pay them for what they do. Don't constantly squeeze them for a bargain. Check up on their work. After you get something repaired, take it home and inspect the repair. Have a buddy or even another mechanic periodically inspect their repairs just so you can either feel more and more confident in your mechanic's work or you will know when it is time to apply for a divorce and find a new mechanic. I've got three mechanics that I have no problem trusting with my cars. If they say it needs doing, or even should be done, I trust them all the way. They know that I do enough of my own work that they won't easily slip something by me. I also pay them for their work. If they asked me to come in to fix their computer systems, I would expect my normal fee of $125.00/hour. If they didn't want to pay that, they could get the kid down the block to fix them up...and then watch where that leads them. Anyway. This got a bit involved just because your statement sounds fishy to me. You didn't have a leak, got the oil changed, and now have a leak and suddenly your rear main seal is leaking? It just doesn't sound right to me. ----- Original Message ----- From: "Lance Bell" <sfnm65@xxxxxxxxxxx> To: <mailing-list@xxxxxxxxxxxxxxxx> Sent: Saturday, January 24, 2004 1:29 PM Subject: IML: ******1965 Crown 4 Door - Rear Main Seal ?****** Hi List, I took my Dad's old 65 and drove it to Albuquerque from Santa Fe. Drove great with the new tires. I then took it to Jiffy Lube to change the oil. An hour and a half later I noticed the oil was dripping and I returned the car back to Jiffy Lube. They told me that my rear main seal gasket needed replacing. I ordered it from the parts store and now I am faced with what to do. I understand ( I have little auto mechanical skill ) that they will have to remove the tranny to put this gasket in? Should I take this to a Transmission store? Or the garage around the corner? Last question....what are your guesses on the cost? Thanks, LB - Santa Fe, NM
