Overview

It improves turbo sump pump effectiveness by creating a slight vacuum, balancing exhaust pressure and turbo seal vacuum, which significantly reduces oil leakage often seen as burning oil smells and blue exhaust smoke.
Show original supplier description
When these exhaust modifications alter exhaust pressure dynamics, oil can be forced past turbo seals and into the exhaust system, leading to blue smoke and burning oil. This restrictor unit optimizes the turbo sump pump's performance, creating a beneficial vacuum within the turbo sump. This improved pressure balance helps to prevent oil from leaking past the turbo seals and being burned off. The result is a noticeable reduction in oil escaping into the exhaust, thereby eliminating oil-burning odors and blue smoke from the tailpipe. A key feature of the PERRIN Turbo Sump Restrictor is that it maintains the original oil flow to the turbocharger, ensuring proper lubrication and cooling. It is an ideal solution for owners who have upgraded their exhaust systems and are now experiencing these specific oil-related issues.
