has any one come across a good way to clean out a blocked heat tube on a single port manifold. i have managed to get in about 6 inches from each end only.

Sorry,
but You will have to do as I did about 12 months ago...
buy another one..
I cleaned Mine out..
but it was rusted right thru...
split right across the back.. so You couldn't see it....
so, its actually rust in the middle that blocks them...
If You clean it out the metal will be very thin in the middle..
waiting the rust right thru...

I see the VW King in Sydney has new ones...
I didn't know You could buy new ones..

I bought a used one from ; alan@stokersvwparts.com.au
in northern NSW.

cheers

Mine rusted through on the outside and was leaking exhaust gases, so I just used a gasket as a template to cut out two bits of galvanised sheet steel. I put the galvanised sheets in with the gaskets on the exhaust side to block off the heater tube and did it all up tight. Job done! This was last summer, and I haven't had any running problems all winter.

Hi
Mine blocked up going to the Nationals in Sydney last year..
Temperature was around 5 degrees during the trip...
carburetor iced Up... engine stopped..

I covered all the vents in the engine lid and below the rear window..
and eventually made it...

I took all the tape off when arriving at the nationals...
When leaving Sydney, I again taped up all the vents...

I then used a manifold heater for the winter... which worked OK [electric blanket type]
until I replaced the manifold....

cheers

PS: it gets to ZERO in Scone in the winter...

if its a 1500 inlet u can buy a new one pretty easy

1200 and 36hp are harder to find

I read it on FACEBOOK so it must be true

PS: You can buy those plates..
and many extractors come with the plates to block off the heat risers.

I just remembered,
I saw in a USA catalog ...
a 1500 single port inlet manifold that came in 3 sections...
the ends were seperate like the twin port manifolds...

now that IS a great idea...

instead of trying to stretch the ends to get it onto the engine
without scratching any red paint off...

[or black paint off]😂

My 1200 heat risers rusted out on the visible pipes at the elbows . I found a corrugated pipe (1/2") from Pirtek fits very nicely. Just braze it on. Wouldnt pass a concourse examination, but it works well. The corrugated pipe bends easily to shape
