I found a '67 mustang with a 302 auto for 2750 near me. The body seems pretty solid and the trans was just rebuilt. The only thing preventing it from being driven is the rear main seal appears to be leaking some oil. How much would that cost to fix, how long, and how much of a pain in the butt is it? I'm 16 and want an mustang to work on as I get money from my job, but i don't want one with a huge problem right off the bat. Any information would be helpful.

its a big job if u know nothing about wrenching on cars it requires removing the transmission the actual parts itself is about 6 dollars but the labor for removing the trans will probably be around 200-300$ how bad is the leak a giant puddle everytime the car is turned of or a few drip a few drips u can live with that

i've only seen the car and the ad for it on the internet, so i have no idea. but i still wouldn't like having oil leaking. thanks for that info, i really don't feel like dealing with what you just said. ill keep on looking for a nicer one.

all ford rear mains leak a little even if its just a drop here or there just part of the 289/302 life

It would be worth checking it out. Just factor in the repair cost with the price of the car. Might still be a good deal.

Replacing the rear seal on a non 5.0L 289/302 involves pulling the crankshaft either out or up far enough that you can fit the seal in and get the old one out. They arent one piece that slide in from the rear like the later 5.0L is. While in there I would also replace the oil pump, check all the bearings (especially since the maincaps need to be pulled) and replace them if needed, or even have the crank ground so you can run new bearings.

Just swappin the seal could be done in the car if its leaking more than 5 drips per minute, but it would be a pain in the rear. Best way to do it is pull the engine and do it on a stand, its easier to get to and work with that way.

But if its just a small oil stain in the driveway, and it doesnt look like the Exxon Valdez has been chillin there, it should be okay and no need replacing. Mom and dad might not want the stains in the driveway, so a large cookie sheet does well to catch it overnight...Dont use one of moms cookie sheets, go buy one specfically for the car.

You first need to determine how much it is leaking. All of these old engines leak some, either there or at the valve covers, etc. If you want a pristine engine you can eat off of, you will pay dearly for it. Replacing the rear main seal would be cheaper than a new engine. I just depends on how deep your pockets are.
