Now as you guy know I have been around the block a few times, not that I am cynical but it takes a lot to impress me, K-Seal has.

My mate bought a Rover 800 2.5 KV6 at auction ---it ran great for the first two weeks then the rad core disintegrated and he truly cooked the engine --- not a good idea in the early version of the KV6.

New radiator fitted and he still had a case of slowly disappearing coolant and signs of water in the oil and oil in the water -- As replacing a head gasket is no joke on the KV6 in the 800 so in went a container of K-seal. The result was amazing --- no coolant loss and even more amazing no more emulsion in the oil side.

K-seal is completely different from Radweld or Barrs Leaks type products neither of which I would use on a modern engine -- Back in the stoneage Radweld was fine for emergency repairs on radiator leaks on older cars provided you removed the thermostat first, while Barrs Leaks had so many solids in it blocked the raddiator cores up.

I tried this stuff a couple of years back in a diesel106 tud3 pug. It wasn't enough to sort out the 2 inch long crack down one of the liners.

Interesting to hear someone else has had a good experience with this stuff.

My line manager who isnt the most technical of guys poured a load in his saab after the head gasket let go and was leaking coolant down the outside of the block.

K-seal sorted it first time...

I must say I thought he might have been conned down the local motor factors for the £12 or whatever he paid but maybe its good stuff after all...

I've just banged a bottle in my BMW 540i.

It was weeping from the rad and had a fairly major hole in the water pump gasket.

Shake the bottle, bang it into a cold system, warm the engine up, 10 mins later sealed fast. Test drove 230 mile round trip straight away and it held!

Good stuff indeed.

P.S. If you go into the Motorfactors looking for it, the bottle is a lot smaller than you'd think!
