There's a bushing behind the seal that the pushrod runs in. If it's worn, the rod can wobble around too much and even a new seal won't work. Yes, the long, one piece pushrod is less prone to wobbling, even with a worn bushing. Best chance for sealing this area is a new seal, new bushing, and changing to the long one piece pushrod.
For the long pushrod, I recommend searching eBay for an original. Some of the aftermarket ones aren't hardened properly on the ends. This makes them wear quickly. Basically, they're junk, lol .....
