Shock Horror - I've touched it today !!!
I'm back in hospital on Monday for more chemo, so in a fit a madness I had a play with the engine, Pete and I got the starter to spin a few months back, but it was clear the engine was seized, so today I thought I'd pull the plugs out and chuck something down the bores and let it soak while I'm in hospital, hopefully it'll turn when I get back.
Anyway, didn't quite go to plan.....
Take one 60+ year old engine.
Clean out round the plugs, and spray plenty of wd40 down, and leave for a while. Try the first plug..... SNAP, top of the plug snapped clean off, bringing the electrode out with it, leaving the threaded section in the block. Hmmm... move on to the others, they all came out fine... phew... so back to the broken one.
So I've got the threaded section stuck in the block with a clear hole down the centre, so I'm thinking easy-outs, so I search round in the garage but can't find them, so them I spy the torqx bits, first I applied a little heat with the blowtorch although I don't think it really did anything, so I applied plenty more WD40 and hammered the T55 bit into the hole in the remains of the plug, fitted the socket and breaker bar, and...... nothing the bit spin in the plug. The next size I've got is T75, which looks way too big, but on the basis I had no other choice, I gave it a few taps with the hammer, and it appeared to be going in, so I gave it a good few whacks to get it right in, fitted the socket and breaker bar and..... it moved !, and wound out fine. Job done.
I have to say I've never seen a plug fail like that before, and I didn't know all plugs were the same thread, I wanted to put something back in the hole so tried an old 216 plug, screwed straight in !
Anyway that was enough for one day, so I sprayed loads of wd40 into the bores and popped the plugs losely back in. See what happens in a few weeks time.
