XJR-s - What goes in my hole?

[fizmo100]

Sooooo whilst changing the air filters I found a nice unplugged hole in back of the offside filter housing, allowing air to be taken in which bypasses the filter. Bad thing!

I'm stumped as to what should be in the hole though, there are no dangling wires or obviously disconnected items, or unused sockets nearby. Can anyone shed any light on what should be in this hole? There is a larger one next to it which is plugged, I'm wondering if the same is true to the smaller one?







Please excuse the muck in the engine bay - a good spring clean is in order when it warms up a bit out there!

Nothing. They are all like that.

Really? Seems a weird design that, it's an entry path for unfiltered air (but only on that side - the nearside airbox is a sealed unit). Any idea what it's there for? Maybe given the state of my engine bay Jaguar designed it to act as a dustbuster...

I can't help the question other than to agree that it's very unlikely to be designed to let unfiltered air into the engine...

But as an engine fan CHRIST is that some engine you have there nice one. I'd imagine this kind of image makes swampy weep into his sandals haha.

So, here are photos of my 2 cars. You'll see that there is indeed nothing plugged in to the hole that is flanked above by the 2 rivets. I'm glad I checked; seems the hose that goes into the big hole has fallen off on one of my cars (the one with a near failing CO emissions...maybe that's the problem!).

These are USA cars, so the fact that they have a hose going to the big hole should not be a concern to you.

Well that certainly sets my mind at ease, thanks. I'm still curious about why they've designed an air inlet that bypasses the filter. I wonder if the design is such that the small hole actually allows air to leave the housing rather than sucks air in? Pure guess work. Someone somewhere must know.

Glad you spotted your disconnected hose - hopefully it'll sort your emissions problem. Very clean engine bays by the way, I'll take that as inspiration!

Well, the top engine is on a convertible with 25K miles and the bottom on a coupe with 9K miles, so they should be clean, especially the coupe!
