those who have solved strange oil burning issues... please help :(

[05civse]

A little background: 91 240sx... I swaped in a 94 180sx black top sr. during the swap i had the head ported, valve job, crower valve springs, crower titanium retainers, new exhaust valve guides installed, and head decked. I put the engine back togeter with a cometic metal head gasket, greddy oil pan, tubular exhast manifold, 3" turbo back exhaust, greddy FMIC, and installed a walbro 255 lph fuel pump.

I got the engine all wired up and it started first crank after i primed it with oil. yay I drove it around for about 30 miles of hard driving at 12-14 psi on the t25 over a month or two timespan (not my daily). then one day i noticed that it would puff a little blue smoke after it had been at idle for a min. or two and i blip the throttle. I did a vacume test and found steady strong vacume at idle and 1500-2000 rpm. Next i did a leak down. All cylinders had just under 2% (each one was exactly the same). I found that it didn't smoke right at start-up and wouldn't untill it warmed up a for a min. or two.

fastforward two months of it sitting. I finally got it insured, licensed, passed emissions and on the road. I have put a three or four hundred miles on it in the last week and a half of daily driving at 7-8 psi with a little bit of spirited driving once a day on my daily route. What i have found now is the smoking has gotten worse, now idling for 15 seconds will cause a puff of blue smoke at take-off. Also, after I am cruising on the hyway at 80 mph for a while or am just crusing the street for a while and come to a stop at a light I will stop and there will be no smoke for 10-15 seconds, then all of a sudden there will be a huge smoke screen exiting my tailpipe... Bad, a light blue smoke just everywhere
(like a smoke machine), but if it starts to do it and i quickly hold the rpm at 1,500 it will stop and be clean.

I thought valve guides, but they are new and it doesn't smoke at start-up and my spark plugs look like they are burning clean and for another reason that i don't remember right now...ha ha anyway, it will smoke a little if i blip the throttle quickly at 1,500 and 2,000 and maybe even 3,000, but just a little puff.

My bov is on the hot pipe and blows a little bit of a oily black substance out of it but not a ton and the hot side of my intercooler is bone dry and clean at the inlet and in the hot pipe itself. is it normal for a little oily crap to come from the bov?

oh, and the pcv is dry and not giving much if any blow-by. and the engine still smokes with it unhooked

If anyone is cool enough to have read this far then I would very much value your input on my problem. I would like to know if there is anything i missed that i could check or if you SR guys have had this problem and know the answer.

Thanks again and I hope you guys can help me out!
