Bit of a strange one but did a timing belt and water pump over the weekend on my brothers car while trying to teach him a bit about cars I’ll spare the details but it took a long time to get right with an assistant with very limited abilities 😉
But in the process of watching me he leant on the engine and snapped a raised part of the camshaft cover not having anything to fix it with properly at the time I stuck it on with araldite and put a heat resistant silicone seal around it to keep the cover air tight.
Now this weekend I really need to get it repaired due to the location and shape of the snapped piece plastic welding isn’t really an option so I was going down the line of a good thermal + oil resistant glue/resin that will bond the piece in, does anyone have any suggestons?

Only high temp i know of is http://www.pcepoxy.com/our-products/putty-epoxies/pc-fahrenheit.php Though http://www.jbweld.com/collections/automotive/products/plasticweld-syringe might fair better JB Weld has all kinds and is a good brand so if that doesn’t fit you criteria look around on the site odds are they have what you need.
Depending on what the specific broken part is you might be able to track one down via carpart.com or at a local wrecker. failing that you could also try the dealer, every once in a while the price of something might surprise you. In a good way.
the problem with high temp adheasives they seem to be plastic specific and im not sure if the plastic is ppe abs etc
and the price from the dealer is $250 so thats a no go and no breakers yard have one that ive found yet its a ‘rare’ engine config and its only used in 1 car that isnt that popular so breakers spare parts are a little sparse

Oof, that must be a good blow to the gut. How much pressure is the plastic piece usually under? is it basically a free floating piece of plastic on a dust cover, or is it under a constant pressure? A picture would probably be the best way to show us what kind of situation this is.
Not the clearest pictures, sorry Had my brother take them as I wont see him till the weekend, The part is under pressure if you remove it you can see the top of the cam so it absolutely needs to be tight and secure (hence the outside being drenched in high temp silicone)
Cant be left like that it’s sealed up but it’s a hack bodge at best so really want to get it sorted before she’s driven more than round the yard.
Did you take a look at the JB weld website? I think you are probably over thinking this. If it is under pressure if you plastic stick weld it would be the best option other then replacement. Takes it off clean it up with break clean then rubbing alcohol and plastic weld it.
yeah I’ve bought some jb weld whether or not it works is yet to be seen but it looked useful to have either way The way it snapped is very jagged and would require a little more skill with the plastic welder than i currently have of the jb weld fails are order the new part and when i take the old one off try and repair it if it fails atleast i have the new one on hand if it works i can just return it.

That seems like a good plan but I would just keep the other one just in case, anything that is broken and then glued back together will never have the structural integrity of a new piece, I was thinking though, if simply leaning on it broke this thing off it wasn’t very strong in the first place, Also I’m guessing a plastic engine cover mounts on this piece, I would just install the new part honestly, It sucks but you would never have to worry about it rebreaking again. If you are intent on using the old piece though, it seems that that piece would receive some reinforcement from the engine cover but it also might add more pressure so I’m honestly about 50/50 this will work and last or not. I just would feel safer in your case to have the new part installed and not worry about it. :unsure:
