Exhaust manifold for F8b

[pony-tail]

Does anybody know where I can get an exhaust manifold or set of extractors for an 800 hatch ?

[Brayden]

Extractors will have to be custom made, any decent exhaust shop will be able to organise a set.

As for a stock manifold, try calling SuziWorx - Mark was having a cleanup and may have one.

[pony-tail]

Already contacted them, they do not have one .

[Brayden]

Okay, then perhaps SuziSport in QLD? I guess if you can't find one then a set of custom extractors would be your only option.

You're looking at around $350+ for those.

I have found a manifold but the flange cone is badly bunt an corroded and it will not seal
Are they repairable ?
If so where would I have to go to get it done ?
I can take a pic but do not know how to post it on this forum .
If a pic. would help, what size (how many kb )would be best ?

[Brayden]

Cast manifolds are generally irrepairable - if you would like to post a pic just email it to admin@tamon.org and I'll put it up for you.

I have finally found a manifold .
Cast manifolds can be repaired (at least they could in 1973 when I did my apprenticeship ) they have to be preheated prior to welding . All the repairs and cast iron welding we did at college was done with Oxy Welders but we did get taught about preheating and mig welding but did not do it hands on.
I have been out of the trade for 25 years . and much has changed since .
It appears that only the vintage and veteran croud repair things these days .
normal "mechanics" just bolt new parts on. and if you can not get parts you scrap the car.
just a side note - I got my first Kei car in 1975 a Honda LN360 Scamp delivery van which I had for many years ( my main car was a yank tank gas guzzler of the very worst kind ) I only sold it to get a Honda S600 coupe .

I'm afraid I'm not quite old enough to remember the days when cast manifolds were repaired.

Glad you found a replacement though.

[pony-tail]

I grew up in north western QLD .
Everything had to be repaired - or you had to wait forever to get the replacement and the freight costs were huge .
Down here in metropolis everything is disposable .

Repairing cast iron manifolds and engine blocks is not that unusual. I have used my carbon arc torch and cast iron rods to do it, though not engine blocks.Smaller items like manifolds can be done without too much preheating because they heat up quickly. Slowing the cooling is the problem. Usually bury in sand. The cast iron rods cost about $5 each so you don't waste them!

[pony-tail]

I have changed the manifold and still cannot get the flange to seal .
any ideas ?

[Brayden]

So it isn't sealing at the head, or where the exhaust bolts on to the manifold?

[pony-tail]

It is leaking at the flange where the exhaust meets the manifold.
With the new manifold the leak is very small but it wil only get worse.

Did you use any sealant on the manifold as well as the gasket? I've used Hylomar before when fitting up gaskets & swear by it. Even stops the oil leaks on my Alfa

That's no mean feat!
