If it's worn seals you may get a repreive with ATP AT-205.

When i bought my latest x, the opg was already leaking at 144k. I really didn't want to go through the massive job so to punt i added AT-205 And the drips basically stopped. Now I'm at 195k (miles) still just add 205 when the drips come back after an oil change.
