Plan to use a can of CRC Intake Valve Cleaner in my Sonata GDI 2.4L engine ... The Intake Manifold is hard to get to without some disassembly of air ducts , hoses , etc. while the PCV vacuum line is SUPER easy to get to . **Would there be any coverage / exposure lessoning to each valve of the CRC Intake Valve Cleaner if I were to apply the cleaner through the PCV vacuum hose versus the Intake Manifold ? ... Thanks in advance for replies !
