PIC link: Header Sealing Washer Suggestions?

[passat TS]

[ Converted text/html to text/plain ]

Huw,

Thanks for the pic.

I think all of this was created by an incorrect part, if the washer on your
picture is the correct one (I bet that it is). As you can see in my picture,
they aren't even close to be flat.

I rather be safe than sorry. I'm on the very end of the engine prep, and after
hours/days of work, I guess I became too sensitive.

Honestly, your answer is what I was hoping for.

Thanks,

Carlos.
