Red face OSV replacement on an 2001 e38

Hi Everyone, I am new to the site and looking for advice or to find out if anyone else has the same problem like I do. I replace the OSV on my car, as a matter of fact I removed the front cover also and cleaned out the excess oil inside the manifold and ensured that the pipe is in place when I reassembled the system. I drove the car for like five miles after the job and it worked fine. Today I started the car and I it came up and idled and ran perfectly on the interstate for like 10 miles, then I parked the car and came back two hours later, when I start the car and there it is again: a large plume of smoke and a whistling sound coming from the engine. Previously when the car smoked at start up it will not do it after driving at high speeds on open road but today it did, also it did it everytime I start the car unlike before the repair where it will only smoke after sitting, Now the smoke does not look like it did before, it seems a bit more intense but does not look like it is created by oil.
Is there anyone out there aware of a similar situation or knows what is causing this problem.
N.B.: The car runs properly, no check engine light and idles smoothly.

I had to replace my OSV twice as the first one was faulty. The smoke came back and a whistling sound occured. Both were the result of the faulty replacement OSV. Mine ran fine for about another month and now I have sporadic smoking on start up.

As I mentioned in my previous post, I am smoking again periodically on start up again. I have also noticed if I let my car idol for any length of time and then drive I leave a large plume of smoke. Any suggestions please let me know.
