Plastic/chemical metal
I need to build up a small area of the inside of my ali inlet manifold ( approx 1 sq cm by 2 mm deep ) to achieve best flow.
What is the best material to use bearing in mind max temp ( 80 deg C ? ) and more importantly thermal cycling? The area is up steam of the injectors
so fuel resistance is not a major issue.
Obviously I don't want the material to detach and fall into a cylinder. Advice please.

if you were nearer. i'd tig it for you. thats really the only sensible solution.

Technoweld is sticky stuff, very much doubt it would come unstuck. Would need a big blowtorch or pre-heating in a domestic oven though first.

I used some chemical metal to do this when I was mucking about with an inlet manifold. It wasn't on the car for long, bt showed no signs of
coming off when I took the manifold off. Always worried me a bit though.

I'm not sure now many compounds would be heat-resistant. Welding would be the safer option.
Different with temporary repairs to other systems, but I'd be like Whitestu - not sure I'd be confident having stuck something to the
inside of the inlet. I'd be too busy listening for a bang... ;-)
