Things never go smoothly for long...

I replaced the o-rings on my Duratec alloy inlet manifold, unfortunately I used ones which were slightly too large in diameter, this caused the channel that holds to o-rings to break:

inlet manifold damage

Intention is to use a traditional style 1-piece manifold gasket or a thermal inlet manifold gasket from Ferriday Engineering and not use the o-rings, this will leave an uneven edge where the existing damage is, options considered to fill the gap are arodite or instant gasket, but I'm not confident either would stand up to the vibration, vacuum and heat changes, any other suggestions on a lasting repair option?

Other option it is a replace manifold, but at £100+ and it would need port matching to be comparable to existing it's not cheap.

Getting it tig welded would probably cost more as all 4 are damaged and would need machining and honing as well.



ps. what's going on with the photos? I get the locostbuilders logo through the whole image.

Yeah, Its hard to see whats going on

Y could use liquid metal them once its gone off use a dremmel to reshape back to how it was.

I have used the stuff on my GSXR throttle bodies and many others do too

Friend of mine repaired internal parts on his bike engine and it was ok

Once you've smoothed it out use the gasket material
