best way to fix this

[incisor]

apart from a stick of gelly...

whats the best way to fix this PIA



one step forward, two steps back... nothings changed

[JDNSW]

1. Barr's Leaks - unlike an expansion type core plug, this is unlikely to suddenly fail.

or

2. If I am correct in recognising where we are, that is a 518272 core plug. It is screwed in. To remove it you will probably have to drain the coolant, allow to dry, apply heat and penetrating oil repeatedly, and this will eventually enable it to be removed either by drilling two holes to take a pair of pins on a suitable lever, one hole to take a large Ezyout, or weld on a bolt. The thread will probably need some attention - I have an idea this is a funny thread, but Brian Hjelm will sell you a tap to clean it up. A new core plug can then be screwed in with an appropriate sealant (see Loktite Range - one includes teflon). The thread does not have to be in very good shape if you use a sealant.

Hope this helps,

John

to fix it properly what he said.

to fix it temporarily

egg whites or bars leak

to fix it somewhere in the middle of the two

drain the coolant, lots of heat + wire brushing and then solder it

Sorry, John. I don't have any BSCon taps but Damien White 07-3807-0798 does. Damien has both taps and dies in this size. These plugs are 1" x 16 tpi British Standard Conduit, a well and truly obsolete thread system.

That looks like a rusted away nut on a stud. Right in the centre I can see a circle like a stud sticking through.

is alloy, gone to powder..

Core Plugs....Core Plugs.......I have a whole heap of them here that I bought to do my two landies.......should be able to get them from British Off Road or from MR.

Ho recently went through this when one of his gave way...from memory it was the one at the rear of the block and also from memory I think Muddy came to the rescue as he has the conduit thread tap to do the threads, these things save heaps of time, but there is a trick to it, otherwise ya just gonna have to sit down with a thread file and pick all the bits out. Make sure you have heaps of band-aids on hand and HAPPY PICKIN'

[isuzurover]

Inc, when I did mine many moons ago, I machined up a tap for the threads, which I should still have somewhere.

If you are not in a hurry I can dig it out when I get back from OS.

[RobHay]

Well!.......................any update on this...or are ya still 'pick'n'

Drill the centre out, then drift it from the edges towards the centre. It should crumble away. Then work at it woth a thread file. Wrap and tape padding around the thread file, (to form a handle, and protect your hands) then really work at it. You need a thread file with internal chasers on the ends of it.
