Hello. I have found a new product that has worked wonders, with my American made Ford that is. It is an additive to oil, gas and the vacuum system. It has cleaned the inside of my Ford engine quite well. And the truck runs much better. Have any of you used Seafoam on your Audi? Have any of you used it by having it sucked up the vacuum system line? If so where the heck is that vacuum line that I am supposed to use?

Thank you very much, Jerry407

 

Yes I have used it.

I poured it in my oil ran it for 30 minutes let it cool and drain to the pan, That works great because these cars are real sludgy.

You can use the vac for the cylinders, Use one close to the manifold.
Anyone will work they all go to the same place.

I put a small T in line and put an extension from that so I don't spill it all over the engine.

You can also use water for the cylinders But you run the risk of blowing a head gasket if you use too much.

I do not know how dirty my cylinders were before I did the sea foam but they were clean when I pulled the heads to replace the valve seals.

 

There's a bunch of videos on youtube of people seafoming Audis.
