gasket for the 6/1 - which side up?
tyssniffen:
So, this seems like a really dumb, but really important question, if in fact it does matter.
I'm looking at a brand new copper gasket for my 6/1, and there's a slight difference between the sides. One side has a bit of a ridge:
and the other side seems completely smooth:
Which side should face the sky, if it matters?
mike90045:
A copper gasket is just a thin sheet of copper. Your pic seems to show some thick material in the middle ?
I think the consensus is that this style leaks easily, and that the style with RTV sealer around each hole and a crimped on fire ring for the cylinder, holds up well.
So I don't know which side goes up.

Hi tyssniffen
Just look at here: https://listerengine.com/smf/index.php?topic=8320.msg103752#msg103752
The original gaskets (and original Lister) has 2 large holes and guides to fit the gasket in correct way!
Cheers

this is the style my machine came with, and what I've been told is the standard gasket.

Well, I've previously used this sort:
and had trouble with that as well. I had one of those in place (perhaps not cranked down hard enough) but after sharing a photo of it, I got a lot of advice here https://listerengine.com/smf/index.php?topic=8711.msg101309#msg101309 that it was the WRONG type. Thus, I went back to the smooth copper.

Sorry, but I don't see this showing *which side* of the copper goes up. It's not the orientation, as the studs and holes force a specific sitting... it's which side is up and which side is down - that's the question.

Hi Tyss
Original ONLY can go one way.
And the side of the ridge stay faced down.
