Hey ~
Well I was just thinking, and well if the 5W-30 Synthetic Oil is leaking through the seals then maybe I Need to go back to the natural oil insted of the Mob 1. The Mob 1 is a thinner Oil. I mean this did not happen untill I started using the Mobile 1. So maybe this could help, is it worth a shot or is the damage done ?? ANY advice would be great ! Thanks,
Paul

Using heavier oil will help reduce leakage but it won't cure worn seals. Only replacement will "cure the disease".
