K-Seal Anyone?

Has anyone an opinion to offer on K-Seal please? It's rumoured to act like Radweld on a leaky head gasket............

I tried 'Barrs Seals', by the same people as 'Barrs Leaks' on my Triumph.....still had to change the head gasket!

Radweld and other similar products work fine on radiators and coolant hoses - they're not very aggressive environments, with relatively gentle changes in pressure and temperature as the engine warms up and cools down. In the old days, people used to pour eggs into their cars' header tanks to temporarily fix leaks.

The environment the head gasket works in is much different, with great changes of temperature and pressure many times a second.

Using Radweld etc isn't going to fix a leaky head gasket, sorry.

K-seal fixes cracked blocks... a friend of mine used it in his 306 TD and its been fine for a year. I doubt it would do anything for a head gasket but its better than Radweld.

Thanks everyone. the sales push at
http://www.kalimex.co.uk
is pretty impressive, and it seems East Sussex at last has made a contribution to the automotive industry! I think for £9.99 its worth a go, after all no-one wants to see a repeat of my "Diesel Head Woes" thread do they?

Worked on my panda, depends what engine it is and what sort of head gasket leak it is. If its an absolutely tiny one from a waterway it might work, did for me. No bigger than 0.5mm though I think, cant remember. Makes your coolant go brown though as well.

I didn't think it would work, but it suprised me.

Well I poured it in and have done a couple of days of around town driving, so far so good. I suppose the real test wil be a long run. Have no idea if it is/was a cracked block or leaky gasket, but before using the additive the engine had "hydraulicked" so bad it would not turn without bumping the car in gear. (2 litre turbo diesel). Does prayer work?

A TD LX Estate I shared last year came with a blown head gasket - and got so bad that that just about hydraulically locked at the end. The face of the head was like swiss cheese, due to lack of antifreeze. A new head and gasket set sorted that, and we did a successful run on Staples2Naples2005.

Thing is, hydraulically locking an engine can cause funnies like bent connecting rods, especially if towing the car to start. Not especially recommended

Hi im a montego man, had an estate for years apart from the odd electical problem on the lights it was great! I discovered k-seal some time ago put it in an old rover that we couldnt drive 3 miles in without overheating. We put it in and sat back and waited for it not to work but it DID! I was that amazed we tried it on a few other vehicles and then we set up a website selling it called http://www.ksealit.com and we have gone from strength to strength adding various tools and products and car and caravan covers. So We have k-seal to thank and we never stop being amazed at how well it works! It has to be worth a look for under £10, just read our testimonials if you are a sceptic because I like them was also a sceptic untill I tried it and it saved me £700! So visit http://www.ksealit.com:)

Just an add to this, my ex's MGF started leaking water from the front of the block shortly after a head gasket was fitted (head had gone soft from previous HGF) and one bottle of K-seal made it last 6 months until the HG went properly, so it does work as a short term measure and i was impressed that it held up for so long.

I've used it on several cars, including turbo-diesel.

I've written about it here...

It has saved me a lot of money, and aggravation.

www.k-seal.co.uk they are great and they saved me a fortune. Got the maestro the extra boost it needed - well underated product, J

over than for its services

so buy it

i have been repairing cars for 40 years,i bought a 1700 td astra 1997 mk 3 off a friend,bad starting from cold hydraulicking in the morning, this was the gm vauxhall engine,removed heater plugs next morning,number 3 sprayed out water when engine was turned over,never used anything before to stop this just used to do the gasket,give this stuff a try mate of mine said,K seal,£7.50 for a bottle,i put it in that afternoon,give it a 10 mile run,morning after started a1,so i took it on the motorway for a 20 mile run at 70+.that was 4 months ago and its still OK,if i had,nt tried it myself i would,nt belive it would work saved me a good few hours work and about £60 in bits,i dont work for K seal or anything to do with them this is an honest report by me,time served c&guilds mechanic,just can,t believe something can do this sort of repair,,

MGTurbo#261 · 21st December 2007, 10:14

Its only any good as a short term bodge. I wouldnt put the stuff anywhere near one of my cars. They dont call it dropping a turd in your coolant system for no reason.
If your headgasket goes the only way to fix it properly is to replace the gasket .. That stuff is awful to clean out, it coats everything with a horrible brown slime.

fatboy.01 · 21st December 2007, 19:10

k seal is not like a dog turd its a liquid think its got small pieces of copper in it

Doh Sorry .. I misread and thought it was the barseal stuff ...
The info on the website sounds good, but anything like that is never a permanent solution to the problem. I put something similar in my LDV to stop a minor water leak from the HG and it worked, eventually it went completely though. But if it solves the problem on an old smoker to keep it going instead of major engine work it has a purpose.

fatboy.01 · 21st December 2007, 20:04

think they named it k seal just to temp repair the k series rover engine lol

guussi · 22nd December 2007, 22:15

i used it in my maestroTDi but i still needed the head gasket doing-if the head gasket does go and causes air pressure build up in the rad-what will happen is the k seal will start to block up the veins in the rad-making the situation worse?

my head gasket ppl said it just blocks things up and advised to stay clear of such additives
