Fix both the burning oil smell and blue exhaust smoke problems associated with your WRX turbo-back 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 turbo-back exhaust systems. Installing these parts on the 2015+ WRX's (FA DIT Engine) causes a change in the 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 cats.

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 the proper balance of exhaust pressure and vacuum on the turbo seals, significantly reducing the amount of the leaking around the turbo seals. This does not change the oil flow to the turbo in any way.

Christian,

The Perrin Turbo Sump Pump Restrictor is the best way to deal with the burning of oil or blue smoke out of your exhaust! It installs easily on the turbo sump vent creating a slight vacuum creating a better balance of pressure so you don't have to see or smell that burnt oil! Thank you for your 5 Star Review!

Turbo sump restrictor.

Install was easy, didn’t stop the oil burning but maybe my turbo seal was just too messed up?

Kiernan,

Thank you for sharing your experience with the Perrin Turbo Sump Restrictor. It's good to hear that the installation was easy, but it's unfortunate that it didn't solve your oil burning issue. The Turbo Sump Restrictor is designed to help prevent oil from entering the turbocharger and causing seal failure, but it may not be a guaranteed fix in all cases. It's possible that there may be other underlying issues with your turbocharger that need to be addressed. If you continue to experience issues with oil burning, it may be best to consult with a professional mechanic to diagnose and address the root cause of the problem.

Regards,
