Hello

i have a 2010 5.7 hemi yesterday i removed the intake manifold and looked under the intake manifold at the valves and was surprised to see a huge carbon build up in every valve tried to clean it with CRC throttle body cleaner and didn’t work will the CRC intake valve cleaner work on removing the carbon build up on the valves

 

Please post pics. Mercy if you sprayed onto valves being held open you have sprayed debris into the cylinders..Not good.
