Rough idle with white smoke

Ok gent I have a 2011 2500 6 speed. It has egr delete race me tuner and I deleted the cvv filter about 3 years ago. I noticed a rough idle about 3 days ago and yesterday on startup it was blowing white smoke. When it warms up the smoke disappears but the rough idle remains. It still has planted of power while driving. The only code is a crankcase restriction code. I was thinking injectors but have been told it could be burned out piston rings and I need to scrap it or buy another motor. Anybody have any advice? Sure would appreciate it since I just paid it off I really don’t want to get rid of it. Also it has 180k miles.

Start checking injectors and compression, all you can do.

Let it warm up and do the obligatory cap test to see if theres any blowby. If the rings are that bad to cause a rough idle, I'd suspect the cap will bounce. If it doesnt, I'd turn to diving deeper into injectors.
