I followed your helicoil video today on my mgb roadster. Thank you the pipe is on.

Outstanding video and presentation

great..videos....John......just..what..we..need

I never knew there was a difference between the manifolds. I have just fitted a Weber dcoe and had to grind it to match my 'HIF' type exhaust as the dcoe manifold has thinker flanges. I could have saved an hours work by buying a £10 HS version. Now I know.......

I was able to do this with MAP gas, it took a little longer but it was possible

Thanks John, what are your thoughts on ceramic coating the manifold to reduce heat transmission?

What size tap to accept the helicoil?

University Motors...and minivans?

Its helicoil as in helicopter! 🤣
