2.25 Block problems

I've a couple of probles with my 2.25 engine which has been stood &
neglectedfor a long long time. First, when I remove the drain plug unde the
exhaust manifold nothing come out. I've poked a piece of wire in and all i
get is a black gooey substance - and not much of it.
Is it possible for the block to crud up so much internally that this drain
hole is blocked off?
Second, I got it running and as the temperature came up a core plug at
near to the bulk head has started to leak. Any ideas? I was going to dry
it all up & rough it up & then try some plasticMetal type goo.

Engine compression is good - can't remember the figures but all within spec.
So I think the engine is pretty good apart from the state of the cooling
system- I don't want ot remove the engine at this point in time until I've
had it running on the road to get a feel for how good it is. And the gearbox
too for that matter.

Any suggestions on the drain plug & the core plug?

Put in some radiator flush, follow all the instructions as per the
bottle.

Take the core plugs out, all except the one at the back of the block
(you can't remove/replace it without removing the engine or the
bulkhead. If this one's gone, then you'll have to remove something, I
suggest the engine, it's easier), remove the drain plugs and flush the
block, backwards/forwards etc etc with a pressure washer. Get all the
crud out you can.

Fit new core plugs, reassemble, (you might want to consider a new
radiator if you can't get a decent flow rate through it) and you
should be good as new.

Don't bother trying to patch/bodge/weld/compund core plugs, it doesn't
work.

It certainly is - particularly when no antifreeze has been used.
The block drain plug get removed very rarely -but it shounds like
you block could do with a good flush.

It's easiest just to replace the plug - only a few pence,
and if it's the one I think you mean it's not too bad to
get at. Stick a chisel or screwdriver through the old one
and prise it out. Clean the hole thoroughly (avoiding bits
going into the engine) and tap the new one in (a bit of
LockTight wouldn't hurt).
