Hahaha! I'm heavily leaning towards the new downpipe having a fundamental effect on my blowby. I just got back from picking up my daughter again from my parent's house. No CELS. Hooked up my OBD dongle. No codes. Car drove just fine.Also, you need to figure this out! We, the forum, can't afford to have you exchanging your car for something else, unless it's another Mustang Ecoboost. 🤞🏼
It is going to be in the back of my mind though, just like @FreedomPenguin said. I'm either going to spring for a whole new PCV solution (upr dual valve with radium plate) or may put the OEM downpipe back on. Don't want to drive around worrying about a puddle of blowby accuumulating in my hotside pipe. But I'll check my catch can again in about 2 or 3 weeks.
Lastly, as far as going for another Ecoboost Mustang. Trust me, this car has been PLENTY FUN. I've enjoyed driving it and I've enjoyed modding it. But one of my life mantras is 'fool me once, shame on you; fool me twice, shame on me'. The entire reason I got this car in the first place, was because I could mod it with a warrantied FP tune. I've meticulously researched every subsequent mod to ensure that I was being as safe as I could with it. After all, it still needs to be my daily driver. But if its not even able to last me 60K miles (I'm expecting 100K), then it would be time to cut my losses. FWIW, I browse the CArmax inventory here and again, and am in love with the Toyota Camry & Avalon TRD versions. I also really like the turbocharged Mazda6's with the skyactiv technology.
This is definitely a to be continued story....for now.....
