BlueDevil Products 00234 Rear Main Sealer - 8 Ounce (Pack of 12)

### Editorial Review The Blue Devil Pour and Go Rear Main Sealer has garnered a mixed reception among users, showcasing a spectrum of experiences ranging from effective to disappointing. On the positive side, many users have reported significant improvements in oil leak issues after using the product. For instance, one user noted that after adding the sealer to their Ford F-150 experiencing a rear main seal leak, the leak appeared to have stopped completely after driving for 400 miles. Similarly, another customer with a Duramax Diesel truck reported a noticeable reduction in oil puddling after the application, indicating that the product can serve as a temporary solution while awaiting more permanent repairs. However, not all customers had favorable outcomes. Some reported that while the product slowed down their leaks, it did not eliminate them entirely. Critically, there are accounts of users experiencing mechanical issues post-application, such as a drop in oil pressure due to potential clogging of the oil pressure sending unit. In these cases, the product either did not work as intended or resulted in additional problems, leading to frustrations and further repairs. Overall, Blue Devil's Rear Main Sealer stands out as a more affordable alternative to costly professional repairs for minor leaks. Still, its effectiveness seems to rely heavily on the severity and age of the seals in question. Therefore, users are advised to approach this product with tempered expectations—viewing it as a potential short-term solution rather than a guaranteed fix for long-standing problems. ### Pros and Cons **
