[pre-xk] MKV air cleaner

Hi there,

How does one get this can of worms to open?

I am taking about the black cannister with steel wire wool
in the other end. I have the bolt off the other end, but
neither of the ending seem to come off. The one that had the
bolt can be rotated but, not pulled open, and the air intake
end will not even rotate. Should it come off easily or do
the edges need to bent open? I hope not!

Cheers,

This cannister has little inside to be worth opening it up. It is
an air silencer and does not perform any filtering/cleaning except
to keep birds out. It is used to remove the hissing sound from
unsilenced carbs and an on some variations it also has a hole in it
to permit the introduction of excess pressurized gases blown below
the rocker cover to get into the fuel/air stream. It basically is
empty inside except for the metal. Having said that, I don’t know
how to open it. Since there are no replaceable parts inside, it
seems perhaps to have been built without opening capability.–

If you were to run your engine in my backyard in May/June, it would also
keep out cottonwood and dandelion seeds. You can dribble some oil on the
mesh, and then it will capture some of the dust, but then you have to clean
it every so often.
All you can really do to clean it is swish it around in a bucket of your
favorite cleaning solution. And it is indeed an early form of positive
crankcase ventilation and hence an air pollution reducer, Having said that,
I should mention there is a drain hole in the cast aluminum air cleaner
manifold to drain out all the oil that accumulates in there due to the PCV
action.

Thanks everyone for your input. I wasn’t going to open it
for cleaning, and was aware that it’s full of, well air,
but mine has a couple of dents and one hole and needs some
paint, so I thought it would be easier to bang the dents out
from the inside.

Also the wire mesh is ok and I know that with oil it will
catch most organic stuff flying around and some dust as
well, that should be enough for me. Also mine being 3 1/2
litre I have the breather hole in the rocker cover so I
don’t want to start customizing this car…rather return it
to the way it was built.

Having recently completed our restoration, I have completed 450 miles of running in. The carb needles are FW as per the book, and new ones. The car is running too rich, with the CO escalating to over 5 at 2,000rpm.
After a long run on the highway, the plugs are black.
We removed the air filter/silencer assembly, and the car is pulling MUCH better, and the CO mixtures are much better. The plugs also have a nice light brown on the tips.
Any tips on improving the airflow within the standard air box? I am thinking of adding some extra vent holes underneath at the rear, covered with mesh.

Frankly I’m surprised that you found a difference with and without the filter. I didn’t think the mesh was all that much of a restriction. Are you sure you cleaned it out really thoroughly? Maybe there’s a mouse or insect nest inside there.
