Blue smoke vs gray smoke - oil vs fuel

i had no idea that it's possible to replace piston rings with just the head off. do you have a quick explanation of how this is done?

it's pretty easy actually. Just ream the upper ridge of the cylinder if needed first, then disconnect the connecting rod caps with the oil pan removed, and then pop the pistons through the top of the block. Reinstall in reverse.

HELP!!!!
PLEASE HELP ME ASAP. I just did a oil change today 5.0 quarts of castrol edge high mileage and white smoke started coming out the engine head immediately. I read it could be from head gasket, to burning coolant, to piston problems. Can someone give me an answer tonight as to what might be happening? This never happened before and im very worried. Smoke is white not blue and comes directly out engine head not exhaust. Like what could i have done oil changes are pretty standard and ive always done my oil and even torque the bolts to factory spec idk wtf happened tonight. Oh and its not like a crazy amount of smoke just a little coming out the red block. My car has been running rock solid till this and i just reached 150k.

^^^ If you have whitish vapor/smoke coming out of the front valve cover breather you have piston ring failure. Its called blow by. Its when the compression rings no longer are sealing enough and the gasses that are suposed to be combusted are instead blowing by the rings, entering the crank case and coming out of the vent system ie front brearher and pvc. The smell is a distinct oil and fuel vapor.

Do you think there’s a chance I’m just burning oil? I’ve been told not to worry and that might be the problem. Or are you almost sure it’s a piston ring failure. White vapor smoke is coming out valve cover never happened till immediately after oil change. And thank you sooo much for the reply bro.

I'm challenging you because I am having a hard time imagining how healthy rings would lose compression immediately after a properly executed oil change. I'm not disagreeing with S2000Junky's diagnosis; rather there's likely a clue in the recent driving history and/or details of the oil change.

After having the valve seal guides replaced, catch can put on, Supra PCV valce installed, heavier oil, mystery oil used, and I forget what all else I did.... I think the issue of blowing blue smoke after engine braking has been solved.
One of our locals, Jason Baur suggested putting an OEM cat on in place of the Berk High Flow cat that I am running.
2 weeks or so ago, picked up another local's cat (Andy Ferger) and put it on.
Just spent the weekend down at Rock the Dragon event down in TN/NC.
Greg, the guy who is always behind me, saw zero blue smoke!!!!
Not sure if the Berk didn't create enough back pressure or what.... but no smoke when Greg would have seen it in the past.... I say, its solved!
Not sure if the Berk didn't cause enough back pressure or what..... but it looks like the issue may be fixed.....

The OEM cat works better because it is a true three-way cat converter, so it will convert unburned hydrocarbons, the Berk is not a true three way cat, it does the bare minimum possible, hence the reason Berk needs to add an anti-fouler on the 02 sensor bung.
