Did a long block swap and everything went well, however front seal started leaking and got worse fast. I had used the new seal included in the install kit. swapped it out with another after market seal, not sure of the brand, but a nice sturdy piece with metal rim...but to no avail...still dumping (maybe bent it a little on install)...went to a dealer for the third try so i could use a genuine mopar product, however it strikes me as flimsy rubber and it went on way too easy. any suggestions before I wear myself out pressing the balancer back on? silicone sealant? perhaps a good after market option?
