1988 Toyota...had a new rear main seal and new clutch put in...It went from 15 or twenty drips in an hour to 15 or 20 drips a week....New clutch BOUNCHES..... A NEW clutch will go in by the guy that put it in a month ago...Free .but I don't want a auto zone Seal......Orginal Toyota lasted 150K...It is a Pickup 4X4....22 re engine...What is the best seal made? This truck was driven from May till Aug and put away for the rest of the year. Probably why the Toyota seal did not last very long....Charlie
 
You may be dealing with an installation failure not the seal. I would use a Toyota seal but the crank may need a sleeve installed (easy and cheap) and high tack sealer applied to the outside of the seal.
If there is any doubt use a sleeve, a rear seal is one of those jobs where good enough doesn't cut it. Sorry but it sounds like you need a better mechanic.

As a side note replace the transmission front seal at this time if applicable.
 
My 2 cents and I'm not a Mechanic.

Next Week I will be having the "front' Oil Seal replaced while doing a Timing Chain Cover 'gasket'.

I bought the Gasket Kit from NAPA, It's a Fel-Pro and included is a Front Oil Seal.

Don't know who made it, but if my Mechanic was supplying the parts, he would have bought the same thing.
The supplied Seal does have a 'small' Coil Spring behind the sealing surface. I like that.
The kit also came with a Sleeve and Lock-Tite.

I think if installed correctly, there would be no problems.

How do you get the sleeve over the flywheel flange?

Cut it and spread it open. LOL

These can only be used on engine that use a one piece main seal as this one does. Engines with multi piece seals usually dont wear a groove in the crank due to their location and the fact they dont use a compression spring.
Repair sleeve
 
NOK brand is what many Japanese car companies use. They tend to last a long time.

I'd prefer to get a Toyota seal of the NOK isn't sold separately.

Sometimes car manufacturers like to have a flange at the rear of the engine with a seal already pressed into it. If that is what your truck uses, I recommend getting the entire flange/seal combo.
