Many members here do not have a catch can and are well over 100K on their non K2 trucks without issues.
No disrespect to those of you that run a catch can and i encourage anyone to follow with what makes them the most content, but the
question remains. If this carbon buildup is such a problem long term why do automakers not include an Oem engineered Catch Can setup from the factory?
Is it an extra cost issue or that engineers feel a catch can is not a crucial component to the longevity of an engine?
