FridgeFreezer Posted December 10, 2022 Share Posted December 10, 2022 I could take a few guesses / best pick from the various goops I have on the shelf but in your position but I would be calling Loctite's technical helpline to see what they suggest, they're very helpful folks who like a challenge!

smallfry Posted December 10, 2022 Share Posted December 10, 2022 Clean and key the surfaces and JB weld. Make sure any porting is done first though, as they will be extremely difficult to remove afterwards. Quote Link to comment Share on other sites More sharing options...

I thought JB weld was one of those super-useful fixes that's also almost always the wrong answer for whatever it's used for? 1 1 Quote Link to comment Share on other sites More sharing options...

To be honest Fridge, it has been the right answer for whatever I have used it for. It has always exceeded my expectations. I wouldnt use it for anything structural, but I cannot think of anything that I have used it for, and it has failed. The automotive things I have used it for include are gluing a mounting lug on a gearbox bellhousing, building up a thermostat housing and water outlet, sleeving up a steel hose outlet to take it from 14mm to 19mm using a bigger tube. Sticking a broken alternator mounting lug on a tractor. All have been done a few years despite me expecting them to fail. I have pieced together a 75 year old toilet pan with it, including under the water line, handle on a saucepan, handles back on broken mugs. 1 1 Quote Link to comment Share on other sites More sharing options...

Badger110 Posted December 12, 2022 Share Posted December 12, 2022 The reason I mentioned CT1 is it does have some flexibility, albeit not a lot. Whether it’s suitable temperature wise remains to be seen.. Quote Link to comment Share on other sites More sharing options...

As impressive as its list of purposes is, the fact it's a construction / DIY sealant & adhesive and not an automotive/industrial product would make me suspicious of its suitability, we know from experience that certain things (EG standard silicone sealant) cause damage to automotive things (lambda sensors Vs acetic acid given off by the sealant) even if they appear to "work fine".

smallfry Posted December 13, 2022 Share Posted December 13, 2022 You should only be using neutral cure silicone sealers on mechanical stuff anyway. This does NOT contain acetic acid (Acetoxy cure) which is really only meant for building applications. It is also cheaper, and does not adhere as well as neutral cure stuff to metals. All proper RTV silicone sealers for automotive use are neutral cure, except blue Hylomar which was Acetoxy, (smells of vinegar) last time I smelt it, which TBH was years ago.
