How to Eliminate Blue Smoke & Burning OIl in Your 2015+ WRX


Fix both the burning oil smell and blue exhaust smoke problems associated with your WRX turboback exhaust or Stage 2 and higher WRX by installing the PERRIN Turbo Sump Restrictor.

Why You Need a Turbo Sump Restrictor

Many customers experience a burning oil problem or blue smoke coming from their exhaust after installing aftermarket J-Pipes or turboback exhaust systems. Installing these parts on 2015+ WRXs (FA DIT engine) causes a change in exhaust pressure, allowing engine oil to escape out the turbo seals. This leaks into the exhaust creating the burning oil smell and blue smoke that many people see. Cars with catless J-Pipe setups experience this issue much more than cars with high-flow catalytic converters.

The PERRIN Turbo Sump Restrictor makes the pump more effective at removing oil from the turbo sump.

How They Work

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 in any way.
