88b2200 Can you post an under the hood picture?
I run an oil catch can.
What an oil catch can does, it keeps unburnt oil vapors collected and trapped so they do not end up on top of the valves as carbon build up. Keeps the intake and valves cleaner.
Not sure it will help as there may be more to your story.
On the factory setup there is/was a hose attached to the top of the valve cover, and it went into the stock breather. At the end of the hose, once inside the air filter housing, it was met with a smaller filter that would need replacing at the same time the air filter was replaced, if not sooner. As it would have oil all over it and sometimes pool in the air filter housing. So what I am saying is, its natural for some oil to come out of the top of the valve cover. Its oil vapor, and then it collects and looks like a lot of oil.
In your case it MAY BE A LOT of oil, we don't know, need pics.
As the pistons move up and down they are generating a lot of turbulence inside the crankcase.
There are holes in the top of the block where oil leaves the head and goes back into the drain pan.
I will use Axles photo here to show that.
As you can imagine as the pistons go down, there is downforce of "wind" and it will push out and up into these chamber ports into the head, thats where the vapors get force out through the smaller breather hole at the top of the cover.
The dipstick popping out could indicate excessive crankcase pressure.
This could happen for a few reasons: the PCV valve might be stuck open, the intake valve stem seals could be leaking and pressurizing the crankcase. Then there is the question that brought us here...could there be excessive blow-by overwhelming the valve cover breather system?
But how?
It's very important to have the PCV hose and filter (positive crankcase ventilation) attached and connected to the intake at the base or below the carb.
Maybe the dipstick is just loose?
