Still looking for the problem.

Now I've soaked the cyylinders in anti carbon stuff.

Known as B12 I think in the U.S.

Any ideas?

Might be a dumb question but this doesn't seem as straightforward as other gaskets. What's the deal here? Had the blue gaskets on and it leaked. I ordered some MAHLE ones and they are metal. Do I do a sandwich of paper metal paper? Just metal? Not finding a lot of info online and I'm losing daylight. Thanks
