Does this pipe belong to exhaust/heating system
OK. Just outside topping up Bel's oil and cleaning her a little. Noticed a lot of sticky carbon type stuff.
Wiping one of the pipes below where I fill the oil and there is a rust hole.
I've looked in my manuals and can't find a name for these pipes or anything about them.
Below link, bottom pic has a 36hp engine like Bel's. It is the pipe on the right and below where you fill the oil.
Can I dirve her until I get a replacement? What will a hole in this pipe do?

It is probably the inlet manifold heat riser. If has rusted through it will be blowing exhaust fumes into the engine bay not nice, and making a bit of
noise.
If it has been blocked off by some one before, it will do no harm to drive it.

Would the exhaust fumes be making the sticky carbon residue over the engine near the hole
I have no idea if it has been blocked off by someone previous
Looks like an immediate job for the New Year. Can't imagine getting hold of a pipe now
OK have made a post under 'Buying........'
How easy would one of these be for me to fit? It sort of looks straight forward

Jen
It is ok-ish as it is. The preheat tube bleads a little bit of exhaust gas off and passes it up the preheat tube under the base of the carb and out
the other side. VW did a pretty snazzy job of this, and what it does is heat the fuel mixture so as it stays "gassesous" and burns
better.
Are you noticing "sweating" on the carb manifold? - cause this is what it stops.
As for the "sticky" residue - well yes, but that sounds as if you are running rich-ish cause it really shouldnt be sticky.
Yep it is something that should be fixed - before winter when you really need the preheaters. But they need to be pulled off and all the carbon build
up cleaned out with a freyed clutch tube so as those exhaust gasses can travel nicely up through and back to the exhaust pipe.
By the way - unlike extractor points the stock exhaust pipe is the ONLY one that feeds the exhaust nicely. You will notice the connection point on the
RHS is near where it leaves the engine block ( a high pressure point), but on the LHS the tube is extended and it is near where the exhaust gasses
leave the pipes (a low pressure point). Normal extractors both L & R hand points are at the same place (high pressure). This means the exhaust
gasses just pulse back and forth and not "flow" like Mr VW intended.
By the way - glenn Ring has one NICE '74 standard. Not a super unforthuneately but real nice none the less. A Gene Berg lover - a REAL nice
motro. If ya bothered check out cal-look.com and go to the Top 20 - his motor is a 1904(?) 90.5 X 74 crank but it puts out like 180HP or something. A
real sleeper that runs 13 sec 1/4's

Hmm, just read the manual now I know what I am looking for. It is not a straight forward job, lots of major things need disconnecting, replacing etc.
Can't see me getting it done before the New Year, just no time left.
Bel was going to do a run from Melbourne to Albury, then to Apollo Bay and back to Melbourne. Is this now unwise until I get her fixed up.
My heater boxes are not connected up
OK how do I recognise this one ' "sweating" on the carb manifold'. When and where should I look? I know the carby, what is the
sweating? |

Literally condensation, water droplets on the neck of the manifold that goes from the cross bar up to the carb itself.
It causes flat spots or hesitation.
I would still go on the run. It is more one of those things for a perfect runnong car.
Ooops forgot my friends!

Yeah - it is usually bad in winter. I didnt run the preheaters at all up here in Sydney.
I would say you are just blowing some carbon build up out the hole.
Take ya time and try and get a good spare manifold cleaned up and them get a quick clean swap done on Bell one day begfore your delightful Mexican
weather hits around MAy

Hey Jen,
If it is just a leak in the heat riser, for a temporary fix you can get muffler repair kits at most auto stores.
My preference would be a kit that containes a thin stainless sheet you can cut to an appropriate size and wire over the hole with the sealer they come
with. Just be carefull with the sealer, some are quite messy and make it hard to repair later on.
Or on the bodgy side, I used to wire some aluminium sheet (coke can) tightly over the hole, worked a treat.
Andy

Excellent, a quick fix for now. Sounds very painless
Just been on a quick run and she is noisier. Carbon build up must have been blocking the hole before and I opened it up cleaning |
