Hi there,
Anyone know where to source replacemnt stove pipes for the exhaust manifold for 308?
These are a metal tube that runs through the cast iron manifold and the lines from the auto choke assembly plug into this tube, if they burn out or get a hole you force exhaust gasses into the carby and choke very messy.
They can be replaced but cant fund anywhere to soure them?
Cheers.
Byron

I was under the impression that this is the stove pipe on the passenger exhaust header?
Are looking for the metal lines for the auto choke?
From what I could see inside the drivers side header, there is a pipe/tube that runs through it where the auto choke pipes connect to, so in theory I guess you couldn't get exhaust gas in the auto choke pipes, unless of course that tube through the header has holes in it???

Sorry mate,
Little misleading, this is on a 1973 HQ 308. Stove pipe is in the RH exhaust manifold and a small metal tube that runs through. One side has engine vacuum from intake manifold and the other goes to automatic choke housing. So gas inside stove tube is heated by the exhaust gasses.
The tubes could be knocked out and replaced.

Do you mean the pipe that is physically inside the exhaust manifold? Sorry for the confusion.

After the actual tube that goes into the cast iron exhaust manifold
Yeah mate, thats the one, My old man, A retired GMH mechanic said they used to burn out and be replaced, also if the auto choke is disconnected and the tube burns our you of course get an exhaust leak into the engine bay.

Agreed with replacement manifold.
Is that your engine in the photos? If it is, what did you coat the manifolds with? Like that nice cast iron look

Yeah mate. Keep an eye on eBay. There are plenty of stock RHS manifolds for cheap.
I blasted my manifolds, then hit them with a high temp paint. I think it was like white knight or something along those lines.....but said was for manifolds and such.
