It will not, I believe, seal areas with strong pressure gradients and little heat. Thus big leaks with high pressure or any area just exposed to nomal water temperature.
That would be cracks in the block to the outside and leaks directly into the combustion chambers.
Well, this a guess only, but I would think this is where you will have the least amount of success.
The largest chance of success is actually around the liners, because the passage is narrow, and the pressure moderate an one directional. If it CAN seal anything, this is IT!! The added advantage is the stabilizing of the liners, which is a big bonus.

As for the question how much the car has done after this repair, it is in excess of 20000km. It could be as much as close to 30000km, but the first reference to milage is somwhat into the thread at 110000, and it has now done 130000.
That is mileage added for the princely sum of 5 Pounds. And the car is in peak condition. No oil or water loss, engine (and car) clean inside as a whistle, and outside too, obviously. Great fuel economy and more life than my 2.5V6!!!

Hi, about time we had another update please kaiser, im about to take the plunge to see if it will cure the dreaded 50-100ml top up after most trips, (everything changed from head gasket to expansion tank cap). Do you think its kind to the water pump seal?

Ha ha. Only good news I'm not afraid to say!!
About 133000km now on the clock, and the car is perfect in all respects.

No water consumption, and absolutely no oil in the water.

I have added maybe half a cup twice since the operation, and I think most, or all, of that has seeped out around the T-piece, which, although made out of metal, could do with a tightening of the hose clamps. Now done.

I can only suggest you give it a try, provided you have carefully checked all the other options, which are

1. Water pump
2. Plastic T-piece
3. Inlet manifold
4. Radiator cap
5. rotten top rubber hose

and, obviously, the catch all

6. any other outside leak

Let us know what you find!!
Good luck

im just glad im being trained as when i had my start of hgf which was only found by chance as car was fine and showing no signs of hgf except a bit of a misfire ,by being shown how to detect leaks using a smoke machine. if i hadnt o been training then i i would of used steel seal as i wouldnt of been able to afford to have the head gasket done .glad i was where i ws when it needed changing ,, and for nothing too

Cheers kaiser, yes ive replaced the water pump (this blew its seal a while back and may have been completely unrelated but id only just added a bottle of steel seal, thats why i was pleased to hear you'd had no probs with the pump seal after adding k-seal) i then decided to do the job correctly and fit the multi layer head gasket for peace of mind , inlet manifold gasket and rad cap have all been changed as well as checking every hose for leaks. Anyway ive ordered a bottle of k-seal off the internet and fingers crossed.

good choice on the steel seal as it is suppose to be the better one of the two ,k seal being the other .your hve no bits blocking up mall water ways like k seal has been know to do ..

I have just stuck my nose into the MG forum on the other side, for a chap with somewhat similar problems, so for him, and the rest of you, just an update!

135000km and going strong!!!
