I'll say again I'm not a guru, but if this was me, I'd take the filter off and see if that resolves the issue, and go through a general maintenance overhaul of the engine.
I know that on diesel pickup trucks, you can take the oil filler cap off, and note how much vapour comes out to determine if theres a blowby problem. Steady wafting is normal, excessive puffing or "chugging" of vapour usually means a cylinder has bad blowby. Is there water coming out of the exhaust? Im thinking its blowby,the rings are shot.
There is smoke and oil coming out of the vent. There are "cures" that might not require disassembly. The easiest is the goo used to free outboards from their carbon. Drunkin, I had an overheating issue on my MD2 Volvo engine way back when.
If the engine is running hot because it is not getting enough cooling water, then the other symptoms like smoke occur. You should check the water pump and see if it is the style where the little deflector cam for the impeller is worn. This is what happened on my engine.
In the water pump, the rubber impeller blades are deflected by a little cam. On older models, this cam was a separate piece that could be changed out--it had a little set screw on the side of the pump casing. When that cam gets worn down after years of use, the rubber blades of the impeller don't deflect as much and so the pump does not pump enough water into the engine. The engine runs hot. My exhaust line rubber hose ran up into the cockpit locker where I could put my hand on it to judge the exhaust temperature, as cooled by the cooling water.
It was supposed to be warm to the touch, but I could not put my hand on the exhaust line because it was way too hot. The engine was stalling periodically because it was running too hot. I called my local Volvo mechanic who pointed out to me the worn cam. Ensure that the guide lug is slid well into the cut out A2.
