Oil smoke out breather

[MadMax_636]

So, I changed my oil since I made the mistake in putting 20w50 into my engine in the dead of winter (Southern GA. We do get some cold ish winters) and my engine wasnt running right. Oil Light kept flickering....

I changed it over to 10w30 conventional oil and once it gets up to operating temp oil smoke/steam starts coming out of the oil cap breather. Which its never done. Its not a Puff puff puff type of flow its like smoke/steam from high temps.

Im wondering if I should switch to a somewhat thicker oil and full synthetic for the time being until Ive saved up the cash for a rebuild or remanned engine.

Im tempted to just see about getting a loan to get a motor. Like safe half get a loan for half.

With the engine running, go to the other valve cover and pull the PCV valve out of the grommet. Stick your finger over the end. Is it sucking on your finger? If it's not, it may be damaged or the line may be clogged. That is what sucks all that smoke/steam out of the engine when it's running.

When the engine is brand new, and when the PCV valve is installed in the one valve cover, if you pulled the oil fill breather out and held your hand over the oil fill hole, after a little bit you would actually feel it sucking on your hand. But as the engine gets older, it has more blow by going around the piston rings. The PCV system can handle this up to a certain point. When the engine starts getting a lot of wear and blow by, it will start overwhelming the PCV system and it will start coming out of the oil fill pipe.

No worries if it still runs good and is not fouling the plugs. I have run engines a long time like this, just keeping track of the oil level. After awhile it will start getting so bad it will start overwhelming the aircleaner area, making it idle rough. What I do then is take the hose off the aircleaner, and get a longer piece of hose and run it down along the frame and into a catch can hanging down there. All that junk goes into the can. You can run them a long time like this, till you get money saved up for another engine.

The 2.8 I have now is so-so. It uses a quart about every 600 miles. I get wiffs of the oil smoke when I get down on the engine hard, I don't have mine going to the air cleaner.

20w50 should not have hurt a 2.8. They were not precise motors with intricate oiling systems.

I'm in N. Carolina and my 2.9 doesn't like the 20W-50 when the temps get down below freezing. And my 2.9 is not exactly "tight" (320K). I got some 10W-40 to change for winter, but it's warmed up a bit the last week or so, and I never got around to changing it.
