Has anyone used seafoam to clean the intake valves? I have a 2008 3.6L DI 90K and will be installing a catch can and then want to clean the valves. My mechanic suggested seafoam. Any good success??

Have used it in multiple small engines with excellent results

Thanks, looking for anyone used it specifically in the CTS engine.

The only drawback I can see is if a chunk of carbon went into the cylinder and messed with your rings or cylinder wall. Mechanical cleaning would probably be better.

Manual cleaning is only 3-5 hours and then the valves are actually cleaned as new. Huge difference if you have over 20k miles on your DI engine.
