Oil from blow by can coat everything in the intake path. (turbo, boost tubes, intercooler,intake manifold and couplers) The oil can cause couplers to pop off under boost and get into the intercooler, coating all the cooling fins and reducing it's thermal efficiency. This will cause a huge loss in power and can cause detonation. Oil sludge can also build up on the intake valves themselves. An oil catch can will eliminate all of this.
