I have a built 383 that is consuming an alarmingly larger amount of oil. Probably around 1qt/1k There are no ostensible external leaks, and there is oil stains on the bumper from the exhaust. It doesn't always smoke at idle; although, it does occasionally. It does, however, smoke under WOT.

I plan to do a compression test whenever I have the time, but what else can I do, especially if the compression tests fine?

Just out of curiosity, what heads are on the car, and have they been ported?
If they HAVE been, were the intake rocker arm bolts sealed?
How old are the valve seals?

How many miles on the short block?

They are stock 243s, and I am not certain how old they are. They are much older than the shortblock, which has less than 10k.

check your crankcase pressure and your pcv setup.

I've pulled some of my plugs, and none of them were oil stained. I emptied the catch can, and there was a tiny amount. My PCV setup is routed fine, as far as I know. This may be a stupid question, but how do I check crankcase pressure?

So, I have good compression in all eight cylinders. Two adjacent plugs had a significant amount of oil residue. Now, I'm assuming that the valve seals are above those two cylinders, or my PCV system is inadequate.
