Head gasket repair (bodge)

[tight fart]

My sons had a few problems with his car and I’m not sure what to do.
It’s. 2008 1.3 petrol ford Ka.
It started when the alternator belt came off, he took it to a garage to get put back on
and they diagnosed a seized water pump, they replaced both and off he went.
A short while after it overheated.
He took it back and now it needs a head gasket.
Now he only needs the car for another 5 weeks to get to work.
I can’t be fussed to do the head gasket (they quoted £600 for)
Are any of the head gasket sealers worth trying?

The car stopped running, my lad got it towed to me, I filled it up with water and tried to start it.
No joy, after trying it a few times I released the header tank cap to add some more water only
to find it pressureised. I'm guessing from the combustion chamber leaking badly.
I then took the plugs out and spun the engine over and quite a bit of water came out.
I'm assuming thats going to be to bad for Steel seal?

He has had 2 quotes £500 to £600, that sounds a lot to me unless theres more involved than i'm thinking?

Bottle of Steel seal it is, I’ll report back.

Can’t even get it to start now, leaking so badly plugs are wet, I’ve removed them a few time and spun the engine over, dried the plugs but they get wet as soon as I try.

Water, I’ve dried and warmed the plugs up, used a bit of easy start but no joy.
