Who replaced the seals? And do you know which seal it’s leaking from right now?
Sometimes crankshafts can get a groove worn into them by the seal, and then when you put a new seal on them, the groove prevents the new seal from sealing and you get a leak. You can put a repair part called a Redi-Sleeve onto the crankshaft. That will cover the groove with a thin sleeve of metal, and then you put an oversized seal on the Redi-Sleeve, and you have a seal again.
Another way to do it is to shift the seal slightly forward or backward on the crankshaft so that it’s not trying to seal right on the groove. But in some motors that’s hard to do because of available space to shift it.
Some people will tell you the only “right” way to repair it is to replace the crankshaft, but I think that’s insane unless it’s a special car and you’re doing a full teardown and rebuild of the motor. By the time you pay a mechanic to do all that surgery, you’ve probably spent enough to swap the engine.
