Fix both the burning oil smell and blue exhaust smoke problems by installing the PERRIN Turbo Sump Restrictor!

Many people experience a burning oil problem and blue smoke coming form their exhaust. This problem can worsen after installing a cat-back exhaust, J-Pipe, or turbo-back exhaust. 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 small and blue smoke.

How It works

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 sup creating the 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 r create any wear.
