180 MG Tech | Exhaust Manifold Repair on MGB 

Wanna change my front pipe on my '72 some day. Hopefully the six nuts will come off with some PB blaster. But the studs are probably shot. Then it's off with the exhaust manifold !!! Helpful video. Thanks John.

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.......

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

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

University Motors...and minivans?

What size tap to accept the helicoil?

Its helicoil as in helicopter! 🤣
