Hello people quick ? If anyone can point me in the right direction. 2012 max with about 160k smokes from tailpipe “white 💨 ” when turning right an sometimes when moving from a stop. PCV valve change,oil change, valve cover gasket changed in the front bank not back. I’m leaning on the rear gasket & cover since billows of 💨 really come when coming from a stop an start on a right turn some oil in spark plug well in the front, I’m thinking I have to replace the valve covers front and back. No signs of over heating HELP please I’m learning as I go gaining a skill DIY I don’t think it’s worth putting a couple of G’s for some repairs I can do my self “patience is 🔑 with me”really appreciate it

 

Hard to diagnose remotely but the tailpipe condition can tell you alot. Is it black and greasy? White and powdery? Or just clean and rusty. White smoke is usually indicative or water unless it is a greasy white! Now that can be from normal cold day idling to a leak in the head gasket or even via a crack in the throttle body (you have water connections to this for the purpose of the "choke."

If it is an oily white, then you probably either have some valve guide seals leaking or rings going.

Send a picture of what your tailpipes look like inside and we can help a bit more.

 

Head gasket can be an issue here as well.

 

It’s a white billow of smoke really when I go over 3 rpm’s the tailpipe is black greasy, I’m taking it as oil, I hope it’s not a head gasket, or a cylinder head “not sure if I’m describing this part right” I’ll take a picture in the morning and see what it does. It’s weird cause when I stop for a few minutes @a 🚦 I’m looking back an it’s a cloud drivers behind me can’t even see I would be pissed if I was behind me an embarrassing, lucky I have a 16 Altima just gotta change the struts easy job👍🏾 Thanks for the response my good people
