EcoBoost 4 Cylinder Rear Main Seal Housing by MAPerformance

One of the most common issues we have seen when it comes to the 4 Cylinder Ecoboost engine has been the leaking rear main seal. Stock and modified motors seem to all fall to the same fate of a warped or worn seal. We have replaced the flimsy stamped factory piece that has a non-replaceable hard seal, with a 6061 Aluminum seal housing, and replaceable seal. Not only will this prevent the oil leaks, but it also offers the ability to service it with replaceable parts, and stiffens the rear of the block.
