id like to hear some peoples past with chemiweld as i have had both good and bad experiances

the problem???
what you used(brand name)???
how long it took to work???
how long it lasted???

welshplug on work truck
chemiweld
instantly worked
lasted 4+ years

head gasket on honda t4 turbo
chemiweld
worked within a minute or 2
lasted till i hit high psi but lasted ages when limping around.

im about to try again with a car well tomorrow and ill post up how it goes.

I'd always been told to avoid chemiweld if at all possible due to it blocking your radiator... I have used 'irontight' though on a few motors and had much success! You put a lot less irontight into the radiator vs chemiweld, so there's no way it can really block up.

We ran a L20B on gas for 3 years with a crook head on irontight. Just gave it a dose once a year, and when we finally pulled it apart, the head was actually very bad, but the iron tight had sealed it up ok. Also kept a corolla and a 4 cylinder BMW going with the stuff for up to 12 months after they had been boiled badly.

is irontight sold in australia
if yes where???

Chemiweld is a cheap way out and should be used in emergancys only. And dont just dump it in. Read the instructions and do it properly or else you will start to block things up.
Find the leak first. If its a pin hole in a hose or a cracked rad its not going to help. Just replace the offending part.

I have seen it used to stop leaks on a VS 5ltr on the water pump and both heads/vally cover. It worked for a couple of months then starting leaving small puddles.

Would you rather trust a bunch of metel flakes in a can or a brand new part when your out in the middle of nowhere in 40deg heat?

ive used it in the middle of a 1200.com cruise....got me through the rest of the cruise and home again so i was happy

then i flushed everything out and fixed the problem

put a can in the daughters 1000 it had a leak in the back of the head fixed it for 7 years just put another can in fixed it again now doing up a new head to put on it

a lady at old work is the chemiweld queen, 3 years almost on modded starlet gt, even track days not a problem... i was against it but she just wanted to see how much boost and how long it would take it. still going strong after manual conversion from auto.

i used it on a lil thumpstar, we cracked the sump on the bike, so drained it all cleaned it etc, and packed a heap of the stuff in it. it didnt work as well as hoped for but, a few days, then started leaking again, may have been the oil or something

yup- Irontight is in Australia... I have grabbed it from Sprint Auto Parts in the past, but probably just about any auto parts store should have it.

As someone else recomended... just make sure you follow the instructions! You add the irontight at x number of mls per litre of cooling system capacity. You run the engine up to operating temp to circulate the mixture and then leave it in there until you have driven around for something like 12 hours, then you drain it out with the engine hot to allow it to set and refill with distilled water. Sorry, I can't remember exact details, but that's a rough guide! I thankfully haven't had to use it for a few years... cars have been reliable

It does stop the leak pretty quickly though.

You havnt specifically said its for the same engine as in the headgasket thread, but if it is then chemiweld wont fix it.

That being said I've used chemiweld and irontite with great success on headgaskets and manifold water leaks. I always carry a bottle with me on long trips.
