Is this a serious issue starting to show through? or perhaps a leaky piston ring? I've hear of lots of people doing this (usually 80's fords) but never really knew why. It doesn't need the "oil treatment" right now, just the one time after it had been sitting for quite a while.
It is possible the engine had stuck rings and the oil sealed it enough to start and free up the rings. A compression test would be a good idea as it could help determine if the engine is due for a rebuild.

The first two pics are of the mid 1960's 230 that someone installed in my 1955 GMC long before I got it. It really runs nice now after some TLC, cleaning and paint.

The last two pics are a 1957 235 that I got a while back. I don't know what I'm going to do with it, but it was going to scrap and I didn't want to see that happen.

The most obvious difference between the engines is the distributor position is centered front to back on the 235 and it is toward the front on the 230. The lifter cover is one long one on the 235 and it is 2 shorter ones on the 230. Those covers are the sheetmetal plate on the distributor side of the block

Post some pics if possible! Hope this helps.
