Playing the Boosey Eb tuba was impossible for me.  Even after 7 years of trying, when I had to use the 4th valve I stepped all over myself.  I sold the tuba, even though I loved everything else about it.  Years later I found out and got treated for it.
The reason you are having difficulty with the left-hand fourth valve is a sensory problem which can be fixed.  If you also have to think about which way is right or left when giving directions, you are probably diagnosed with whateverthenameofitis.
I had it and it can be fixed.  Contact an Occupational Therapist.  It's a simple procedure and can be cured in a couple of sessions.  I am not joking, this can be fixed!  You will need someone who is a certified Occupational Therapist with a state license or a national license (OTR).
Let me know how it goes for you, if you decide to follow through.  It's cheaper than buying a new horn.  Good luck.
