The Caliber SRT-4 being a high horsepower turbocharged car runs a significant amount of piston-to-wall clearance. The cylinder pressure from the forced air creates more heat in turbocharged applications when compared to non-turbocharged engines, thus DCX designed a "loose" engine for added safety and longevity purposes. Unfortunately, a byproduct of an engine that allows a lot of blow-by is oil residue makes its way past the PCV system and ends up in the intake manifold, and many other places.

Oil residue in the combustion chamber of an engine is bad news, and can lead to really bad news with respect to how your engine runs. We have been selling a real solution for a while now that will actually separate the oil from the air flowing between the PCV and intake manifold. It sounds easy enough, as many people have tried to adapt simple catch cans and industrial water control valves to remove the oil from the air. Those products do work OK but only separate a small amount with respect to how much oil is actually passing through the system. Enter the AGP Oil Accumulator.

Our three chamber oil separator gathers the airborn oil particles through the middle chamber. Oil is separated from the air through the filtering media and drains through a perferated aluminum plate on the bottom side of the middle chamber then accumulating in the bottom chamber. As this oil gets filtered through the middle chamber, clean air is then filtered again and exits through the top chamber. This three chamber system design provides the best protection against unwanted oil making its way to the combustion process.
