[Healeys] Core plug extraction

[Simon Lachlan]

Thanks for this, but I’m not talking about opening a lip, just banging one
lip inwards ie with, say,m a round drift of +/- 4mm. Banging it on the lip,
at 90° to the plug’s flat surface, trying to push that side inwards so the
other side swivels outwards into the jaws of your grips. 

Yes, opening a lip sounds like a recipe for disaster.

Driving in a spike and levering outwards works but can be a real pain if the
thing’s been in there for 50 years and/or depending on what sort of vile
gloop the PO used as a seal.

Trying to open a lip as you describe sounds tricky with the potential for
gouging the wall of the plug opening.  I just drive a spike through the
centre and lever out the plug. They are quite soft, compared to cast iron,
and it has never presented a problem.

 

What tricks do others have?

I noted the other day what a ghastly job that is. Always possible and nearly
always bl**dy awkward.

I’ve seen clips of guys – always with the engine in pieces on the bench –
who just bang one lip inwards until the plug swivels in the hole. Then they
just grab it with a mole(?!) wrench or similar and hoik it out. So easy.

I love my car dearly but I always expect the most cussed things of it and
I’m seldom disappointed. Surely if I were to bang in those that I could
reach, they’d just vanish inside, never to be seen again???
