So changed turbo old one was leaking oil and smoking occaisionally. Once turbo swap was done installed a bcv (aka) gillis valve it wasn't adjusted right and I over boosted now smoking terribly. Any easy way to tell if it is headgasket or turbo?
What color is the smoke?
It is white
Could have also melted a hole in your piston like i did about a year ago.
Its what happens when you have too much boost and not enough fuel sadly. All that damage to mine was caused by a cracked rubber line in the tank just above the pump. It pumped out lots of white smoke as well just a heads up although i hope this isnt the case for you.

It still had plenty of power so I'm kinda not thinking that is the case nor is it making any noises
Sounds like a head gasket.
does it only smoke under boost?
how much is too much?
If its an ebay generic turbo it may have just blown a seal. They tend to have sloppy bearings and blow seals pretty fast. I've had them start leaking oil within 2 weeks. do a compression test. The cylinders should all have similar psi if the head gasket and pistons are intact. if there is more than a 20 psi discrepancy pull the head and check the pistons and head gasket.
If you still have plenty of power, you must not have blown the head gasket between cylinders. Check your oil and coolant for signs of cross-contamination. If they look normal, focus on the turbocharger.
