BTW, I just went online and discovered that the possible source of the smoke may be a cracked crankcase ventilation valve. Two of them (OEM parts) are less than $50. I watched a youtube video on replacing them - ooks easy. The videos suggested checking for cracks in CCV's before doing the expensive valve seal work. Also, one of the videos indicated that this may particularly be the problem if the smoke isn't constant, which is my case. Thought I'd share this info with you.
