On my Bosch IP job, the front cover gasket hasn’t leaked, but I wanted to re-seal it.
There are two covers, aluminum and steel. And two gaskets as a result. The steel cover gasket is NLA from Mercedes.
There is a visible difference.
There’s also hardly any sealing area. So the thin one intended for the aluminum cover might be “good enough”. But I assume it rides in a milled groove in an aluminum cover, and it will shift out of place on the steel one.
For now I put some of this on the surface:
And put the old gasket back on, screws torqued to 10 in-lb.
So I’m thinking I probably want to consider cutting my own. But what’s the right way to do it by hand. I used to make seals for fuel cell stacks, but we had fixtures with razor sharp hole cutting tools. Which I don’t have, but maybe need to get? Or is there a better way to punch holes into rubber stock? I know I can get sheet rubber at McMaster and just need to find the right one. Most of it is razors and straight edges.
Anything else I need to know?
