I made a post a while back on the redblock PCV system and a major oil leak I was having; now I have all the front seals and valve cover replaced on my b23 engine (they didn't look that bad to me) and I decided to go ahead and replace the oil pan gasket, and when I had the oil pan off I noticed that the plastic tube - which presumably goes up to the breather box on the side of the engine - runs all the way down the side of the oil pick-up tube down into the sump. Please forgive my ignorance but how is this tube supposed to vent the crankcase, because it looks like the bottom of it would be submerged in oil much of the time? I've taken apart a number of (American car) engines in my day to rebuild them and I've never seen such a thing. Did Volvo make any redblock engines with the PCV vent in the valve cover as it is on most engines? Seems like that would be a better system. Even the old Stovebolt Chevy engines that vented the actual crankcase didn't have a tube that went way down into the sump (they just had a draft tube that plugged into the side of the block).
I'm starting to see why my car's engine compartment and underneath look like I drove thru an oil slick and that this engine might not be worth spending my time and money on (although I suppose no engine is perfect) because some things on it seem terribly flawed. Also, unless you have a turbo engine in your 240 these little 4-bangers really were under-powered for the size of these cars, and for having such tiny engines 240's really don't get the best mileage in the world in stock form (aerodynamics could have something to do with this, too).
