My machanic came round today to start working on my bus.
He found a hole behind this pipe.
What the best way of tackling this?


 
If its in the back of the rusty pipe, the pre heat pipe, then i would say weld it, but you'll have to take the manifold off to do it. Looks like your missing an engine seal and a bit of tinware there as well, both rather important on an aircooled engine.
 
I think he means the one in the cylinder head tin, you will have to remove the manifold to get the tin off to repair it.
 
If you mean the hole in the tin id put an ask up in the for sale and wanted section. You should be able to get an original unholed one for 20 notes rather than welding.
Will look better but it all comes down to budget I guess.
Needs sorting though. Itl be bellowing hot air into the cool area of the engine bay. Not good.

Sorry I didn't explain myself
Kids running around and I had to go collect the Indian takeaway lol

See that rusty pipe, there's a little hole on it , round the back , prob about 3mm dia .
 
I have a neighbour who does a bit of welding.
If we dropped the engine out so we could get round the back of the old rusty pipe in the pic
And just welded it up!
Prob the easiest way to go about it I guess
 
I could help as I have nothing to do tomorrow and a spare you can have ... problem is I'm in Canada :msn4:

Why drop the engine? You've got a twin port manifold so it'll come out fairly easily without having to remove anything other than the carb.

I tried for hours to try and remove that manifold without taking the fan housing off, it wasn't happening for me. I cannot imagine how it is possible to take it out without removing the alternator first(which is what I ended up doing).

I'll never have to do it again because I'm running twins now, but if its that easy to take out can you please explain how? Maybe there's a knack to it.

Do you mean the perfect round hole with the vertical raised bits left and right? That looks like space to but a clip, perhaps one that holds spark plug wires?

Or is it not that hole?

Surely a rubber bung, or just a blob of silicon sealer would do for the time being? You need the side rubber sealing though, and Reezevan on here is selling a tool to straighten out the metalwork where the seal should run.

Blob of exhaust paste on the hole and a jubilee clip over it will stop it blowing for about 12K miles - well mine did!
 
Did we agree on which hole it was? :mrgreen:

If its a tinware one, then fit the lead clips or stick a gromit in there.

If its the hole on the manifold joint, thats the adjustment space ... its not a problem.

If theres an actual hole in the pipe itself that we can't see, either replace the pipe, take it off and get it welded, or as BJ1 says, block it off somehow.

To remove the pipe with the engine in place, you'll need to remove the carb and the alternator/dynamo which involves some fan housing jiggling, but its all possible.
