FE Oil Filler Tube - Baffle

[REDSC400]

Hi Guys:
Over the years I have been having a tiny but irritating oil leak which I have narrowed down to a drip(s) of oil that come out of my oil filler tube breather cap.

After a hard run, what I notice is that the material inside of my oil filler cap is saturated with engine oil. This woven material, inside of the cap, then drips oil on top of the valve cover then makes its way around the front of the cover.

I pulled the cap and with a flashlight I noticed that the oil filler tube does have an internal baffle insert. The problem is that the baffle is situated 90 degrees wrong. The slot is vertical instead of horizontal.

This allows oil to apparently get by. If it were in the tube 90 degrees or 1/4 turn either way different, then I imagine I would not have this problem of the oil getting by.

I have not tried to twist the oil filler tube for fear of making a bigger problem.

So much for the background... now for the questions....

How is this oil filler tube (which goes into my intake manifold) held in place? Is it press fitted?

Can I turn it? Will it turn?

Or can I just buy (I do not know from where) a new oil filler tube baffle that I can push down into the tube in the correct aspect?

All ears for advice.

BTW, the intake is an aluminum Police Interceptor manifold. There may be a picture of the filler tube in-situ in my photo gallery.

What has worked well for me on my 289 that I have seen done extensively on the vintage car racing circuit is to carefully cut a piece of fuel cell foam and stuff it in the tube, then install the breather cap. It really works well.

Art,
It should be pressed in. Someone may have use lock tight when they installed it.

Rick's idea is fine and I solved the same problem in a similar way with different material.
Get a brass thread "scrubbie" from the supermarket, the kind used to scrub old sinks. Gently pull the fibers apart so they're not so dense and crankcase pressure can vent through them. Put a loose zip tie through it from top to bottom to use as a "handle" so you can remove easily to add oil.
The pressure vents but the oil splash is trapped by the brass. Never gets dirty either.
Good luck,
