I am almost positive that my CCV is again done for, again....

I had a retired BMW master tech. (after 28 years) read the live codes on my car last weekend.
I do NOT know if this was for real, since I briefly met him at the outdoor seating area in-front of Starbucks on a Saturday morning.
He was all greasy/dirty (from what looked like working on a car), and had a scanner that read live-codes.
He said the catalytic number was 14, and should read 0, and some other number (I can't remember what...) reads 4, and should read somewhere around 14...
Hence, the reason for my hesitant acceleration when hitting the gas...
He said the timing was retarding...
And, he said the car's high crankcase pressure is the reason for my car's failed oil-pan gasket, and why my fuel pump is making noises (suspected failing again - pump was replaced just last year).
He first suggested replacing the Purge Vent Valve, then later, said to spray a whole can of B-12 carb/throttle body cleaner through the throttle body while the car is running...
This sounded kind of "old-school" to me...
Thoughts....?
I am so tired of changing/replacing this damn CCV...
I last replaced my CCV with the Cold-weather version in Jan. of 2010.
I think I have approximately 15-20k miles on it, maybe...?
Believe me, I definitely have been thinking HARD about deleting the CCV, and installing an Oil catch can....
Recent:
I don't hear a lot of noise coming from the fuel pump area now...
I switched gas stations, and have been using Quick Trip and Shell.
The sounds started when using the Ethanol-free Conoco station, so I stopped going there.
I have noticed that at start-up, the car spits out a LOT of bad fume, almost gasoline smelling...
Running rich?
I also did notice a little bit of a weird sound (humming/ buzzing) from the engine bay at start-up...
I am suspecting:
1. Disa Valve
2. Secondary Air pump/ air valve/ clogged hoses
3. Jet pump hose between gas tanks
And, I have had the car checked again for codes being thrown, and there is still NO codes...
However, I KNOW there is something wrong...
Oil analysis:
Thanks!
