Core Plugs

[Guy Gregory]

Hi chaps, as far as I know all core plugs in Talbot
Engines are screwed in, usually 1.5 mm pitch. Doddy.

I had a detailed tutorial on this from Vinnie. It is threaded and you need to make a new plug but you need to add a taper to it using a die chaser in a lathe to get it really tight fitting….


I shall reply and suggest Vinnie or just answer the question!

This post seems to be missing something, what is the start to it? Over the years I have had taps made to clean out the threads in the block when the old plug has been removed to aid starting the new plug. They are all 1.5mm pitch and a variety of diameters. I know I don't have a complete set for all Talbot core plug threads but I will lend those I have if anyone requires them.

Hi James
hope you're spoiling Sue! You're right - the post started in 14/45 seized engine but since then , I started Doddsworth tips as he posted tips about core plugs. Hope you're not too confused
Cheers Guy

Hi Guy, I am always confused where a computer is concerned, as you should be well aware. I asked a question somewhere about the Dodd sewer as I have just put the radiator back on the 95, so I'll ask again. Is there a drawing of it so that I can make one whilst we are locked in? Nothing has changed, I have spoiled Sue for the last 40 odd years! James.

Hi James,

I've got Doddy's sewer at the moment, it's going to go on Whimsey when I get that started (soon!). I'll post a picture on the appropriate thread tomorrrow to show what it is. I have 3D printed an additional part to it but that'll be clear on the pics.

Hi Martin,

I look forward to th pic.

Hi Martin,

I look forward to th pic.

James.

Well reminded!

I have made a 3D printed plug to accept the stainless gauze and to trap the sediment so it falls in to the sump part.

Hi Martin,

The cars with water pumps have a 32mm o/d top hose, whereas I think your Fuggle and Whimsy have bigger diameter. I have coming to me an equal rubber "T", 32mm i.d. and a cap. I think I can use that for the main body. Doddy has said he will send me a piece of gauze, looks like you have enough to last several lifetimes! I am intrigued by your gauze holder, I had worried about how to retain it but perhaps a scrunched up lump would not offer to move anyway. I will experiment when the parts start arriving. Many thanks, James.

I'll obviously have some of Doddy's gauze left over would you like me to send you some?

Hi Martin,

Doddy has said he is sending some to me, so perhaps he has another roll of it. I will give him a few more days and if his fails to materialize, I might take you up on your offer. Many thanks, James.

Hi Martin,

I now have a roll of Doddy's gauze as well. I just need the rest of the kit to arrive, thanks for your offer. James.

This is my interpretation of Doddy's sewer for the 18HP cars and upwards. The main ingredient is the 32mm rubber Tee which slides onto 2 short pieces of top hose material. The third leg of the Tee is fitted with a rubber cap, again using a short piece of top hose material. The filter material is a piece of Doddy's woven S/S mesh - looks like chicken wire made for very small chickens (about the size of half-grown mice)! It scrunches up very nicely and has a lot of lateral springiness and will not move when fed into the rubber hose on the radiator side. It does not impede the flow of water as a test with the hosepipe proved.
