Thread: chemiweld for blown head gasket

Ha ha ha, thats funny!
probably not a good idea

I certainly wouldn't do it

I used A similar product an found my radiator cores were full of the sealer. Fix it properly than doing a costly repair after

Hi I have had friends use it, some times it work and most times it don't, if I was you get it fixed the right way first time as a TD5 is a expencive engine, spend some money and do it right then you won't make more problems for yourself...Ashley

ChemiWeld is a very good product for what is was designed for - a temporary fix for cracks in heads etc - it is not a radiator sealer (like Bars Leak) and it doesn't clog radiators - however it is not designed to fix head gaskets.

However I have used it in an incorrect manner for various leaks and it has worked in most applications for at least a while. If the leak is minor and you are not in a position to fix the head gasket by all means try it - BUT - it is likely to fail at any time resulting in a cooked engine.

I know the previous owner/s who put chemiweld inside the cooling system on the rangie must have been thinking it would fix the pressurising issue of gases that were leaking into the adjacent water jacket ,once chemiweld is inside your cooling system , it's a Bitch to clean it all out , I had heaps of it on the tip of my finger when I reached inside the water jacket to try and pull some of it out , this is after I spent hours flushing my cooling system prior to pulling my heads off to find the chemiweld still exists all over the inside of my cooling system , I suspect to clean it Properly the bottom end of the Motor needs to come off to get it all chemically cleaned.

6 months ago I put Chemiweld in my P38 to hopefully give me some more time from the cracked block. Well.....

I just had my 2 year P38 old radiator rodded out. He couldn't even get the rods halfway down before they hit, what felt like concrete. $540 later I have a new radiator. He also kept the old tanks to show me. Never again.

Don't do it, save the money and fix it properly. BTW my engine had done 260, 000kms, so I wasn't too worried at the time. Had it been a TD5 or such, there was no-way I would of done it. It was hard enough as it was.

Wish I knew all the above before giving the Landrover specialist the go-ahead.
I will give them a call in the morning to find out why I was not told the implications of using the product. They suggested to me do this first before replacing the head... What a nightmare!!! The service center is a recommended
repairer on the site in Perth...

Just what to get my car back to health!!! Thanks for all your replies Vince.
