2013 ATS 2.0T Lux, 2017 MB C300 Coupe
I'm not looking to start any arguments with the following question, just looking to increase my understanding of this issue. Many, many on this forum have stated that a catch can is the way to go to reduce adverse effects due to accumulation of intercooler gunk that may be one of the causes of blow piston heads. Furthermore, they say that the catch can is a very easy install and can't do any harm. So, if these claims are true and of an apparent big benefit to the car, why hasn't GM/Cadillac given any hint that this is a good approach to solving the piston problem?
