Leaking 2a

Hi guys,
after returning from a 8 month holiday overseas I was getting my 2a (ex-Army, 2 1/4 Petrol) ready to bring back from Central Queensland to Brisbane.

At the shops I notice a big green lake under the car, open the bonet and find a waterfall ;-) coming out of the RH rear of the engine block.

Some sort of plug seem to have gone missing, I can not detect any thread and strangely enough the hole is not round. Well the hole itself is round, but whatever fits in there has to be the figure of an eight.

I found in the forum a picture of an engine block and have circled the plug which is missing. (I apologize to the owner of the picture for using and altering his picture without authorisation).

Now ... what kind of plug am I missing here. Any suggestions on how to fix this temporarly. I tried a 50cent piece with putty to the outside of the hole, it lasted about 500m.

All I know it is not a welsh plug ;-)

Any thoughts ?
Thanks,
Dante

Ok .. replying to myself ... looking at information

Land Rover parts - WELSH PLUGS - 2.25 PETROL

I deduct that part 527269 is still in place (that is why I don't have a thread) put it has a hole.

I am now worried that it has a "Whitworth" thread. How easy would it be to find a replacement in the middle of the night. Provided I can get it out

Any thoughts on this ?
Thanks,
Dante

G'day All, The plugs you are refering to are of an alloy construction and the thread is 1" x 16TPI Conduit, the plugs are readily available thru the usual suspects. You will have strip down parts of the engine like in the picture and job made easier by removing LHS guard have fun cheers Dennis

PS I have taps and I would suspect someone in that part of the world will have them as well.

Hm .. won't be able to do any of that for now.

I think I will get a high tensile bolt (short), and weld it into that plug. This way I should be able to undo it when needed.

Not sure I would be able to remove it the easy way as the one of the extractors is quite rust and on the other side I am not sure I would be able to remove the plug that easy.

Let you know how it goes.

Thanks,
Dante

mate whereabouts in central qld are you? close to emerald?

**Dinty** · 18th April 2008, 06:07 PM

G'day All, I'm no welding expert but I'm certain you cannot weld steel to cast iron, so best of luck mate Dennis

PS and you will really bugger up your block.

G'day Dante

That looks very much like the "Plug for Redundant Heater Hole" (Part No 527269) an alloy plug that screws into the Block and yes, it has 2 lugs in it which makes it look like a figure 8 when corroded away.

BUT that looks like you have a hole in the block alongside the plug

if so the block is a throw away

is the hole in the block???

That plug should be available from FWD motors in Brisbane (07 3848 9323) or British Off Road at Forrest Glen Qld (07 5445 1094)

cheers

G'day Dante

Sorry

I misread your post that is NOT YOUR BLOCK

but a sample photo

cheers

you cant "weld" it but you can braze it up however thats a one time fix and not something you want to do unless you have plans to pull out the engine and rebuild it in the near future.

epoxy and alfoil also works but the same criterea apply.

**Dinty** · 18th April 2008, 07:49 PM

G'day All, That red circle wasn't there when I posted earlier either, otherwise I would have said it is 1 1/8" dia plug and I knew it wasn't your block and others have said fix it properly or why bother asking for advice
