Many people with 2015-2021 WRX and 2014-2018 Forester XT experience a burning oil problem and blue smoke coming from their exhaust. This problem can worsen after installing a cat-back exhaust, J-pipe, or turbo-back exhaust system. The installation of these parts can cause a change in exhaust pressure that allows engine oil to escape out of the turbo seals, causing the burning oil smell and blue smoke. The PERRIN Turbo Sump Restrictor quickly eliminates this issue!

The PERRIN Turbo Sump Restrictor makes the turbo sump pump more effective at sucking oil out of the turbo sump. This in turn creates a slight vacuum on the turbo sump creating a proper balance of exhaust pressure and vacuum on the turbo seals, significantly reducing the amount of leaking around the turbo seals. This does not change the oil flow to the turbo or create any wear.
