Air escaping 1.3 endura

[Todpot1992]

Hello, there seems to be air escaping from the top of the engine when accelerating. I’ve circled where I have heard it coming from. It’s a new sound only in the last week. Is it a problem or how can it be resolved

Thanks in advance

I'm not familiar with that engine, but that spigot looks to me as if it might be part of the crank case ventilation system. In that case there would ought to be a hose in that area supposed to be connected to it. Particularly if the spigot is clean, that indicates that something was connected until recently so you should be looking for the trailing end of whatever used to be connected.

That is your inlet manifold & if that were a full hole it would be air entering as the inlet manifold is under vacuum not positive pressure.

I suspect it is just something that you have just noticed rather than something new, plus if it were air entering/escaping it would run like a bag o' sh!te..

It’s the sound of 1976 trying to desperately escape from a more modern car.

Check that the hose running from the oil filler cap to inlet the manifold hasn't split...

(it's the hose above the 'ura-e' bit of endura-e in your photo)

Get it sorted, you've got unfiltered air getting into the throttle body / intake, this is like running without an air filter and it can cause damage to valve seats and grit and dusk make their way it, if something the size of a small stone got in there, it'd take out a piston.

Thank you very much for all your responses, all very helpful will have a look tomorrow. It adds to the character of the car
