White smoke from tailpipes

I'm having an issue of white smoke coming from tailpipes on startup and when engine is up to operating temperature. This happens after I replaced the ccv, after some time of this , I decided to delete the ccv and install a oil catch can instead hoping it would fix this problem but no luck. Still have the white smoke, a faint tick from the spark plugs coils side, and a drone felt in the seat going into the floor like its coming from the exhaust. I don't think its head gasket or hope it's not atleast, pulled spark plugs and they are dry, coolant is still at the same level no decrease, engine has not overheated well the guage never hit red always stayed in the middle. Can someone please shed some light on this situation? I have tried to describe it with as much detail as possible. Also no check engine light. If needing anymore info please ask , I seriously just need this fixed

First thing is to determine what the smoke is. Oil, coolant, steam?

Next would be to see how well the engine is running by looking at the important values, such as MAF, long term fuel trims, and then read the trouble codes. OBD Fusion is good for that.

The tick sound could just be your lifters. There is a prescribed method of bleeding your lifters. Just Google "BMW lifter bleeding procedure". So that could take care of that. Make sure your oil is good.

My CCV is brand new. Two months old. My scan tool shows almost ideal fuel trims. It runs smoothy.

The white smoke I get briefly and occasionally. For example, I recently had to bleed my coolant system and let the engine idle from cold until it was at normal working temperature. It was a damp cool morning. For the first 30 degrees I had "white smoke" coming from my exhaust. Probably steam to be honest. After that it was invisible.

My car has just passed it's annual government inspection. Three days ago. No problems with exhaust gases. Limit on HCs is <=200 ppm. Mine were 28 ppm which is pretty damn good for a 16 year old 135K engine.

So maybe your white smoke isn't something you need to worry about too much.

The concern is oil. Right? Take it to a garage and ask them to run an exhaust gas analysis on it. It might be a good investment.
