Technical Water neck question

I think my water neck was leaking a bit. Took it off and the o-ring is a bit rough looking. I have one of these aluminum rubber gaskets. Can I just pull out that o-ring and replace it with that gasket or is the seal compromised due to the neck's o-ring design? Thanks!

 

Lots of unknowns in this post. Sure, swap it for a regular gasket. Add some RTV, it'll seal up. Good luck!

Two threads today same questions
Yes that gasket should work
Make sure straight with file
Snug torque about 15 ft pds

 

A little 3Bond wiped on there fix it.

 

I'd replace it with a stock type neck that does not use an O ring.

 

There are two types of thermostat housings available, a die cast housing and an aluminum one. The die cast one lasted about a year on my car because of dis-similar metal corrosion. I changed to the all aluminum and it has lasted several years now. The zinc in the die cast housing was the problem. I now use a sacrificial anode radiator cap. Check your housing and make sure it's not being eaten away. I have also found the gasket as you show to be prone to leaking.

 

We do not know witch O ring thermostat housing Op has , I have cheap,
