Head gasket sealer

    Has anyone tried any of these?

    A mate asked me to check his daughter's Vauxhall Meriva 1.6 tonight. Starting problems apparently. He said when he checked her car there was no water in it!
    I got it running - seemed ok at first but loads of steam coming out of the exhaust and then running rough at idle. Almost certainly head gasket. No oil contamination.

    It is a bad blow judging by the amount of steam coming out of the exhaust.

    I suspect the head gasket sealers are in with a chance on a weeping gasket but would have no chance in a case like this. I would love to be proved wrong though.

    If it did manage to seal it , it wouldn't last that long till it went again but if the car is scrap otherwise, might as well give it a go

    Had good experiences with "k-seal". I was impressed when it worked on a crack (into the sparkplug hole) in a motorbike head. I thought the stresses involved on such a high revving little motor would be hard to cope with.

    and will you be to blame when the owner is stranded on the side of the road ?

    id recommend the proper fix and have nothing to do with sealants

    Most of the gunk tipped into cooling systems to seal them is aimed at buying motor traders time, time enough to launch a dog onto the auction rooms/Bay of thieves and onto some unsuspecting sole.

    Steel seal may work and they used to offer money back if it didn't.

    If it's that bad though it really wants a new gasket, could be a cracked head or block

    I had an issue with a vehicle loosing water just couldn't find it and I was going to Cornwall in two days! Asked local motor factor who I trust he advised K seal, works a treat still fine 2 years later when I sold it. Its worth a try before you start spending on it.

    Someone I know tried Steel Seal for a slooooow leak in a pickup - worked until he traded it which backs up what @8ob suggested.

    Internal combustion engines create water as part of the process, any car will blow water out of the exhaust in great quantities if it's been stood cold for any time so I don't see it as a symptom of a blown head gasket. You don't usually see it because you are sitting in the driver's seat.

    I have seen it several times. Looks like the car is powered by steam:laughing:.
    Very different from the usual wisp of steam you get in cold weather!

    Such a small, simple engine. Head gasket is a day of a job if the head isn't warped

    I agree with the positive comments re k seal it can get a car out of trouble and keep working for a long time. I used it on Mrs. ZX9's Rover k series engine, how appropriate :) it out lasted the rest of the car.

    Well my mate has decided to get it done properly. £450 including head skim and new rad.
    Car is a keeper so prob best thing.
    I test drove the car for him before he bought it. I could smell a faint whiff of antifreeze then and suspected head gasket. Mind you it lasted 3 years :laughing:

    If you can smell the coolant it's usually the heater matrix, my daughters Corsa did it a couple of years ago.

    The big issue I've seen with some of these products it the heaters not working as well as they did before particularly on lower settings as they clog the paths. I have used Steel Seal in the past and it worked, I have no idea how it works because it looks like lime cordial. Most of the other products show up quite clearly in the coolant as they make it cloudy but steel seal doesn't so you'd probably never know it had been used.

    I suspect that's what our local garage used after they did the H/G on mrs Robo's Freelander and it failed a few days later so they had it back for a day and put some liquid stuff in it which cured the leak, but we traded it in quickly before it went again.
