damn looks to tedious for me. ill stick with the dealership for this job lol

so when exactly do u know u need to bring ur car to get carbon buildup cleaning done? when it throws a cel? performance loss/engine misfires?

Your dealership will only clean it under warranty if it's throwing an error code. Make sure that they don't just clear the code but actually clean it.

I didn't have a CEL or any indication of build up and my valves were caked, as seen in the photos. Major performance loss. Some people have misfires when the build up gets really bad and that will throw a CEL. At that point, the dealer will cover it under warranty.

i would be very interested. thanks very much to both of you guys for doing the work and taking pics.

Not a problem, I think Brian and I learned a lot through this process too. When we do his car, we will make a DIY.

Good job!

One thing I will mention is that I used a very small wet/dry vacuum attachment to suck out any carbon/seafoam residue, which worked very well.

I have an air compressor at my house and we would blast compressed air into the valves to blast out any excess liquid residue left over from the mixture of seafoam and carbon deposits. I think a vacuum would have been cleaner though haha we will try that next time. I'm not sure if I have a fitting that small though!

I picked the attachments up at Sears for like $9 bucks!
