Air box bleed nipple snapped off

Went to change spark plugs, in trying to remove the thin breather hose from the air box the stem has totally broken away, just my luck, any idea how to fix or is it a replacement box?

Has this engine seriously overheated in the past..?
You seem to be breaking parts nobody else has issues with.

Makes me wonder if the parts have been 'cooked'

No I don't think so Ok I did wiggle it a bit and the stem is at best 5mm its another design part that requires taking apart but was not made beefy enough, the hole is also off center so may have made it worse, and, I replaced the pipe when we got the car(18 months ago) so it would not have had any oily deposit on it to help it slide off in future, like today?

Having a coffee and am in the process of trying to glue it though I'm not too hopeful it will hold/last?

No, this is another common and well-known issue with the 500.

Many of these get broken by careless fitters at franchised delaerships during servicing; it's not at all unusual to find them damaged or broken.

Some have fixed this by gluing them back together, but if you can find a suitably-sized brass fitting, you could likely engineer a much more durable repair that's better than new.

Many, if not most, secondhand airboxes will have this part broken or damaged. New ones are stupid money.

It's another example of the 500's weak technical design.

There are always some in eBay. About 25, as mentioned worth checking that part is intact though.

Re: Air box bleed nipple snapped off

Might a screenwash pipe connector of some sort make a replacement?

The black spigot is removable, but you can't buy it separately.

Anyone with a lathe could make a far superior replacement.

Be careful when removing these pipes; I find it easiest to first loosen the airbox, then work the pipes off once it's free of the throttle body; this puts less stress on the fragile bits. As I've said before, if you've had the car serviced 'professionally', the spigot may already be broken or damaged. Working on the 500 is not for the cackhanded.

I don't think it's a build quality issue; it's more about weak technical design (most of the money seems to have been spent on styling) and cheaply made parts.

Basic assembly quality is light years ahead of anything we ever managed when we had a meaningful UK car industry.

You're forgiven!

Let us not forget though, that an Italian owned car company is building its cars in Poland, so those of us that have in the past bought and presently buy the 500, we aren't/weren't in any way supporting the UK car industry at all. At least with the Nissan's, Toyotas and Honda's in the list in the link, they're built by British workers on the whole, to a very high standard.
