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.
Many customers experience a burning oil problem or blue smoke coming from their exhaust after installing aftermarket J-Pipes or turboback exhausts. Installing these parts on the new FA20DIT motors causes a change in exhaust pressure and therefore allows engine oil to escape out of the turbo seals. This leak into the exhaust creates a 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 cats.
