Seafoam or similar on S63 engine?
Hi guys,
Just wondering if anyone has done seafoam or similar intake manifold / valves cleaners on S63 engines. Probably good to do it as regular maintenance as direct injection engines get messy around the valves, just wondering if someone had some experience with this and recommend where to inject it. Cheers! |

I don't have any specific knowledge trying seafoam on this engine but I would guess you don't want it going through the turbos. I suppose it's for a limited time so it might not be a problem but personally I wouldn't take the chance because I don't know enough to take the chance.

surely no good to go through the turbo, and I dont think it will clean all that much that way because it needs to expand and foam up.
The idea of the product is to have it fill/foam up the intake manifold which will break down the carbon deposit/gunk/oil etc and wash them off and burn. I wonder if removing the stock air filter boxes would give me me any access to the intake manifold. |

Of course it will do injectors and rings, but how do we clean valves?

Ideally want to spray this directly to the intake manifold while engines warm but off so it can fill the area with bubbly foam and break the build up down. |

The issue with GDI engines like ours is that the intake manifold or intake valves won't see any fuel at all, just air and some airborne oil with it which creates mess around the valves and valve seats. |

Hmm this advertising material from the CRC product claims that it is safe to spray before the turbo and it actually cleans the impeller too. Maybe I should try that product

I have always been curious if these actually do anything and this thread has inspired me to do a bit of testing. I just pulled the intake valves out of a N63 (valves are nearly identical as S63's) with its infamous valves stem seals, going to place the valves in jars of each of the popular valve treatments (Seafoam, CRC, LM, Berryman, Marvel MM, etc) heat it all to 200F, let it sit for 20min, then see what the difference is with the before and after.
While not exactly the same environment of a running engine, it should give us an indication if they actually do anything at all. All of the treatments and the hotplates to do this are on order and will be here today, will post results within the next day or two for all those Interested. |
