E46 cvv valve questions help cvv eliminated

Ok this is my first post on e46 fanatics and I'm pumped but got sum questions bout the common faulty cvv valve.
Ok short story purchased my 2000 323ci for dirt cheap prior owner said engine was bad but from what he told me and what I know I knew it was a bad cvv. It's a warm climate 323ci in a cold climate lol. Ok so got car home and I eliminated the cvv valve after I ran a comp test and checked over everything. I bypassed the entire cvv system and just vented my valve cover to a catch can. I sea foamed the secondary air valve as it was clogged also(small ports on combustion chamber). So I let the car run n got it to not snoke at all runs and drives awesome I do have a cell from the bypass and will be reinstalling a cold climate cvv this weekend. Ok so 2267miles since I bypassed the cvv on my way to work this morning car alarms out brake light on abs light on traction control on which from my understanding could be a few things like speed sensor in wheel ect. Well I started to smell oil as I was driving car didn't get wa has perfect coolant perfect oil and isn't running rough or anything but when I got to my work I noticed the car is blowing our the same water vapor it had when the cvv was bad. Not as much at all but enough to irritate me. So my question is is this from my eliminated cvv valve ? If so why didn't it do it from the get go seeing as its been fine for over 2200 miles. Or if not it what should I check? Should I leak down test? Seeing as oil and coolant are perfect and not mixed I wouldn't usually do a leak down. But just thought I would get the great advice from other E46 fanatics. Thanks guys

change oil

I am not sure but the seafoam I think messes your oil up and you might want to change it.
