@@alexanderSydneyOz Why is it a joke? The silicone sealant was more of a joke that was holding this piece in with when I bought the car 4 years ago. JB Weld is up to the job and took the weight on that repair as shown. Full video is here: ruclips.net/video/3G1QI6JniC8/видео.html
As a cheap repair I think this would of been 100% fine! You know yourself this isn't a proper repair but the damage is on the top of the head where there is no real pressure. I accidentally punched a hole in my sump and I repaired it with the exact same stuff. it held up for fine for ages until i got a my replacement and time to do it Nice job mate
I recently learnt not to repair a sump to save £30 as I did just this but as the metal was that thin it was clearly going to leak somewhere else and it did. I think the engine might have got destroyed through lack of oil. I assumed the owner would check their oil like we all should. Sat outside my house now waiting to be my next video series.
Yeah its hit and miss, I guess it depends on factors like location.. Mine was a dent and split in the centre of the flat bottom of the sump. Drilled the edges of the crack to stop it getting bigger, filled the crack with liquid gasket. Then a coat of jb weld on the top and bottom. That held for over a year haha the bottom jb weld did come of soon after the repair but it never failed. I'm not saying it wasn't a time bomb waiting to happen but these repairs can get you out of a bind
Epoxy is incredibly strong stuff … about 10% as strong as welding as I recall, which is still very strong and quite suitable for anything that doesn’t have to bear weight or take impact or high pressure.
@@jamarmiller3608 The heat from an engine head? I think it would be okay. It should only get to about 110°C max unless it's right next to the exhaust manifold. Most epoxies can tolerate 200°C
You had me at first cleaning up the area to be prepped for welding but then you went and used that jb weld and then you made me believe that you're a fool 😢
@@biggusdickus9046 can you care to explain why you say that as I see nothing wrong with this repair. The JB Weld is rated way higher than the heat of a cylinder head and JB weld advertise it exactly for these jobs.
I used JB WELD to plug a casting gap in a 6-71 Detroit head. It was allowing oil to enter cooling system. This was in about 1978 and I ran it for at least 10 years before selling the shrimp boat.
Use a centre drill in future for the milling machine. You only need to touch it down to make a small indent into what you're drilling. It will stop the drill bit walking..
No going to seal. Metal expands when the engine warms up and It will definitely crack the jb weld. I'll only do this if it's temporarily. I would suggest tig welding for any crack cast aluminum jobs
Great job. Really like that you included the test in the video as well. No reason these repairs can't be suffice for the right applications and with good preparation like in this video. One thing I always recommend is to clean the surface with pure isopropyl alcohol just before any chemical application. It can't be disputed as to what that stuff does for a cleaner surface to bond to. Even when you think it's free from leeching, dust, grease or anything else, total piece of mind if you do that before application.
@@CoatsandGaiters no problem, it's as professional as it's going to get for that type of repair in my opinion. Prep was good and do like the use of the drill bit, that's no doubt helped and again probably suffice. Was good to see you test it as well, is always good to put our work to the test rather than thinking it'll just do. Might as well break there and then, rather than in situ lol. Just to add to the previous comment as I don't like to edit OPs, I did mean to put "peace of mind" and not piece lol. Also, for anyone who is to use pure isopropyl alcohol, it is extremely flammable and should be handled with care. Thanks again for the video and all the best 👍
I used simple 5-minute epoxy to fix the speedo cable on a motorcycle. Etched the cable and end piece first with hydrochloric acid. Repaired end piece was mounted under cam cover of DOHC air-cooled motorcycle, so it got very hot and vibrated a lot. Epoxy was still holding strong when I sold the bike 50,000 miles later.
Keep in mind, boys and girls…, If it comes out of two tubes, it is plastic. Plus there’s no real stress on a valve cover bolt, if that’s what that was.
You can weld it and make it stronger, heat the block up to over 200 degrees, use an income rod, when done,wrap the block up,and let it cool down slowly, I’ve done this process before, never a come back.
JB Weld epoxy says it can withstand 287°c and the cylinder walls on an engine get to 190°c so it should be fine as long as JB Weld are telling the truth.
I 'repaired' a stripped sump plug thread in an original Mini with a product like JB Weld (Chemical Metal). Lasted for years and the compound made for a perfectly serviceable, reusable plug thread.
@lanzecki yes. I mean don't get me wrong TIG would 100% be the way to go. However if it's between this method or a harbor freight stick welder and an aluminum rod... I'm gonna go with the aluminum rod.
@CoatsandGaiters it's gonna be messy and splatter a lot. Rods burn fast too. So make sure you have the area isolated. Edit- it's important to remember this version wouldn't be brazing. It'd be an actual stick welding rod rated for aluminum
JB weld has a higher rated temperature than a cylinder head would reach so should be ok ....."The only disadvantage of such a repair is that the engine heats up and this connection may not withstand high temperatures."
Just a note to anyone who believes this rubbish: epoxy adhesive can glue a broken part back on, but it cannot be used to apply stress from a a bolt, like what the broken part is for. This is just someone creating paying YT content.

The strength of epoxy deteriorates quite quickly with the application of heat and I think a cylinder head gets pretty damn hot.
