It looks like the rear main is starting to leak on the '78 transmission Am. Small but, puts a few drops on the floor after sitting for awhile. It ain't gonna stop by itsowndamnedself.

Short of a replacement, is there any "fix-it" juice that anyone has experience with that might work?

While I am not much for these types of things I would try something, off the shelf, if it might work. Snakeoil(s) notwithstanding….

 

You want truth, or a lie?

There is no way to swell the rubber in the rear seal without swelling every piece of rubber in the whole car.
The valve seals WILL NOT last 1,000 miles after you put in the magic cure.
Cant tell you how many valve springs I've pulled off that have a blanket in there instead of a valve seal

Easy fix on that car.
Pull the transmission. pop out the seal.
grease the rubber in the new seal. set it in there with the tool
put the transmission back.
Varoom varoom

Now, the lie
Pour the motor magic in, and run the car for 8 million miles, and it will grind the valves, replace the rings, put in all new gaskets, and all new seals.

Said bottle of magic mix is only $9.99, and you can buy it for a limited time, just give me your credit card number, and I guarantee I'll be happy for a long time. & Tom will be responsible for anything that goes wrong

 

Damn truth-sayer.

 

as the paste eating window licker said, i have never seen anything that works worth a damn.
but it is fairly easy to change the seal

 

Hey Charlie?! Do you also sell a bottle of that "magic juice" that you can pour in a 7.3psd, and get it to 700hp with stock injectors and turbo while improving the transmission to handle the power?!!

 

don't need no bottle of Charlie's "Magic Juice" John.

just put a big "C" sticker in the back window. that "C" is good for 800 HP, and 922 FTLBS torque.
it will also raise fuel mileage to around 97 MPG.

 

I guess I should also put a stack in the bed!

 

that is good for at least another 467 HP.

 

Or a 8" can under the back right. They mean its fast too

 

I think you are all missing out! A Warm Springs Indian Reservation, Oregon product (made back East with stuff the Warm Springs have never heard of) is guaranteed to remove paint and rust, clean injectors. Just add one bottle in every tank of gas or diesel and give a tremendous boost in horsepower, cure measles, mumps, kidney and liver ailments and balance problems....Heck, it's even good for putting the "party" in the Saturday night parties!

I think Jim's got the ticket! I bet that can make you look good to the wife, if you can get her to take a sip!

Campsprings John needs this one to go fast

 

Leave it to a dodge idiot to put a mailbox on his exhaust.

 

Ya. Tom has one on each of his plow trucks

He has the big blue one from the post office on his dump truck

 

and i have a big "C" sticker on the sides, and door.
