Head Still On, ... Cleaning Carbon
Hey All,
It turns out my head gasket is fine so no need to pull the head, ... Whew! However, I wanted to clear out any carbon off the head and the top of the pistons if I removed the head for the gasket. In the past with modern engines, I have always slowly poured water DOWN a running engines carburetor to blow off carbon through steam pressure. Question here is, How does one pour down an updraft carburetor? Possibly though the vacuum port on the intake, but even slower? Regards Bill |

It could be put thru the vacuum port, or, use a spray bottle thru the carb throat.

Re: Head Still On, ... Cleaning Carbon
Why? What kind of problem are you having with carbon?Are there chunks of it causing detonation or something?The A has a low compression engine,there is always going to be a little black in it.With modern gas and oils carbon hasn't been a problem for many years.

Re: Head Still On, ... Cleaning Carbon
Hi Patrick,
I'm not sure spray bottle could deliver enough and it would already be well on its way to being atomized, but I guess I could give it a try. Keith, I looked inside the cylinders with a borescope and did see some carbon buildup, not a lot so if I can knock it out now all the better. I have no previous history of the car except from the Widow of the owner which passed 10 years ago. Regards Bill Sent from my SM-G920T using Tapatalk |

Re: Head Still On, ... Cleaning Carbon
Thanks Bill for reminding me.
I do have some seafoam here and I use it in the gas tanks of my modern cars. My Carb and Manifolds are brand new, so I think I'll just go through the vacuum on the intake manifold. I might need to speed up a bit, age is on my heel's and is trying to catch up to me. Regards Bill |

Re: Head Still On, ... Cleaning Carbon
I think you’re always going to have a little carbon on the tops of the pistons. Find the sweet spot of your gav and don’t run rich.. (I wouldn’t run it lean either)

Re: Head Still On, ... Cleaning Carbon
Use Seafoam as recommended above. With the engine running, and a small flexible tube in the vacuum port on the intake manifold, just put the tube into the bottle of Seafoam and it will be sucked up into the engine... probably stalling the engine.. but ok. Let it sit for awhile, 15 minutes or so and then re-start the engine.... it may smoke quite a bit but ok.
