Not so quick background go to bottom for a tl;dr
Catless downpipe was installed in Nov 2015. The car NEVER smoked before this install but from now on smoking was the norm and alleviated by holding my idle at 1200 till the smoke cleared. You're probably thinking why didn't he get a catch can dummy?
Well couple reasons, one being it wasn't a garunteed fix. If you search still smoking; catch can; you'll see threads of poeple still having the issue.
Reason two, If the smoking didn't stop even after a catch can and gutting the pcv my last resort would be my dealership; having to explain myself to a ford tech why I gutted anything on the car because the Internet told me to, well I just didn't want to be put in that position. Mind you I respect the knowledge of everybody on here and I'm just trying to convey how outsiders or anybody who doesn't use these forums would look at the situation.
Anyhow back to to the smoking issue.
So since my first mod in November 2015, the smoking issue has kind've been annoying not really cause it didn't always happen. I've installed more mods since then and had the car tuned in Feb/March. Nothing tune wise nor mod wise has cause more or less smoke.
Frequent oil changes every 4-5000miles using rotella t-6 w/wix filters
Car has 13k miles currently
Always fed Shell and Chevron 93 gasoline since day one.
New NGk whatever lower temp properly gapped plugs installed at 5k miles
Car originally had 22 miles when I bought it and I always let it warm up every single key cycle.
I don't track the car and I decline many minivans and gt's who want to race on the highway.
So as you can see I think it's safe to say I follow the mustang6g bible as far as maintenance and car care goes (minus the catch can).
Things got weird on my second oil change [MENTION=17112]10[/MENTION]k miles, which is done by yours truly. Smoking stopped on first start up and was gone for about 16 key cycles spanning 3 days. Then came back worse. At laptop lights drive thrus everywhere. I was making "fat clouds" as they say and would win any vape competition. Lol. I messaged some people and a catch can was recommend duh. A week or two goes by as I research which one to get but the smoking just stopped?? I can idle for 5min or 20 min, after a long drive or after just staring it up. Not even a hint of smoke. The only thing that's changed is the temperature outside. Living in San Antonio,tx the weather just started being crappy hot and humid mid April. It's been 3k miles and no smoke has come out. I don't know if this is good or bad. I want to get it checked out to see what the valves look like and see if there is oil in my intake but wanted to see what you guys thought.
Tl;dr
Car smoked on off @idle for 10,000 miles. After oil change [MENTION=17112]10[/MENTION]k car smoked heavy for 3 days then vanished for 3,000 and counting. Is this good or bad? I can't tell if there's smoke that comes out during the occasional wot pulls to get on the highway, but idle is smokeless for sure. What do you guys think?
