Seafoam? 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??
Re: Seafoam? Have used it in multiple small engines with excellent results Re: Seafoam? Thanks, looking for anyone used it specifically in the CTS engine. Re: Seafoam? 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. Re: Seafoam? Correct. We see scouring from any solvent based upper induction cleaning. It is impossible for particles to not be forced between the cylinder wall and piston while performing one.
