Seafoam - Toyota Yaris Forums

One thing though I've heard very often is that it shouldn't be used on cars with over
100k due to the fact that carbon and other stuff might be helping seal things together. If the seafoam breaks down whatever gunk is holding good seals together, it can make things worse.

That only really happens if you are using seafoam to try to correct a problem or fix something. If you are using it as part of your general maitanance then you should have no problem. Same thing people say about synthetic oils causing oil leaks at high milage.
