Core Plug size?

[Lotz-A-Landies]

Anyone know the exact size of the core plugs in the side of the S1 2litre block?

If they are the same size as the 1.6 litre, I can go and measure my spare ones for you,

Pretty sure they're the same!

Whoops forgot to ask you which core plugs!

The threaded ones are 1" British Standard Conduit, 16 t.p.i.

The cupped ones I also bought from Dunsfold, let me know if you want them measured but I have installed them, so it might be tricky to measure,

Diana :

If your after the three cupped style plugs in the side of the block.. the size is rather odd , something like 1 and 15/16" ... can't remember exactly from memory. BUT, most engine rebuilders and even auto parts shops stock brass ones in many sizes . I managed to buy some in Warragul much to my amazement.

I think the old size is 1"/31/32 or 50mm. but i stand to be corrected.
I have a box of them somewhere..........

very timely post as i have just done one on my 57 today, yes they sell the 50mm ones at repco but they are a tad to big... armed only with a bench grinder sorted!!! a little bit at a time and in it goes all good now
i think they are about 1mm to big

Hi Diana
when in UK last
i was told the thread was British Standard Pipe
the 1600 are smaller, 2ltr are a larger diam.
if you want some I have several sticks with 5 or 6 plugs in a threaded lenght
they are wound in and then cut off flush
send me a PM
cheers

It's the cup core plugs I want the size for (the ones that some people wrongly call Welch plugs).

I am one of those people that would call them Welch plugs, and the holes are a pretty common size in Welch plugs available at Bursons and the like in Brass.
I have a steel one that I just take in and say give me some in brass.
I have not seen the round, hit in the centre plugs for some time.
Will get out the sliding measuring stick later today and let you know the outside diameter of the plug, this is often stamped on them.
The thread on the sacrificial anodes (Al plugs in the block) is in deed British conduit not pipe.

PS there are some stell plugs about with a brassy finish, good for a week or 2.
