I noticed that some blue-ish smoke was coming out. I replaced pcv, this seemed to solve the problem but after a few days o noticed the smoke again. What could this unusual smoke be a cause of. Also I noticed that when the car is running if I take the oil cap, oil starts pouring in a fountain-like manner. This has me really preoccupied. Is this oil coming out the oil cap abnormal? Can the two problem be related. I appreciate the help. Thanks.

Blue is oil smoke. Could be valve seals or rings worn out.

Oil would spill out of the oil filler cap if it is removed with engine running, the faster the engine rpm, the more would be thrown out.

You need to be monitoring your engine oil level as the blue smoke indicates it is getting to the exhaust, usually caused by worn valve seals (at least 70 % or more) and the other from the rings.
