CCV and oil pressure pondering

[taosx5]

I have been reading dozens of threads on this and here is what I have concluded. Just wanting to see if most of you agree.

I have two 03 X5's, 4.4 and 4.6is. Never had a problem till now but the 4.6 (91K miles) just started blowing small amounts of oil out of the oil filter cannister, enough to leave a 3" diameter puddle. I suspected too much pressure in the oil system but did not know why until I started reading the forums. Yep it is the usual suspect, very cold at -4 F outside and 40 in garage, short trips under 5 miles. (Btw, I did not know I should avoid this behavior until now). Mechanic-ing is not my strong suit expecially in a frigid garage with sub 0 temps outside. If it were warmer I would probably attempt this DIYS.

It has done this twice, about two weeks ago and again today and never a spot of oil at all. The first time it happened I did not correlate the cold and short driving distance. It seems to stop once I start regular driving habits again. I have only lost about 1/8 mark on the dipstick. So here are my thoughts. Taking it to an Indie and having the CCV replaced, oil separator inspected and cleaned, replace all of the vacuum and oil hoses, and do a visual inspection on valve gaskets to make sure they are not leaking.

1) Would this be the proper protocol?
2) Once the engine and oil heat up, will the pressure be released and the oil leak stop, meaning am I ok to drive it for a couple of hours to get it to the Indie shop?
3) Any other good preventative maintenance items while this is being done?
4) I assume avoiding short start up and stops during the cold winter months?

Thanks in advance you all rock.
