The "muck" that is coming out is byproducts of combustion that are vapors when they are first created. These vapors must be sucked out before they condense.

IF the vapors are allowed to condense in the engine, they will in time form a surprisingly hard and tenacious sludge (like dirty furniture varnish really) on every interior surface of the engine. You might think this is an unimportant cosmetic issue, but not quite. The sludge will build up on the wire mesh screen that covers the oil pump oil pickup tube, which is submerged in the oil sump. The openings in the screen will get smaller and smaller, starving the engine for oil more and more.

Your oil pressure light will not light up in time to save you, it only indicates when pressure is not even enough to lubricate the engine at idle speed.

If you have the time and energy, and if it is an easy job, you might even consider removing the oil pan (on my cars an easy job with the engine in the car), cleaning it out inside, and inspecting and cleaning the screen for the oil suction tube.

To clean this muck off of PLASTIC or STEEL parts, when these parts are removed from the car, you can use inexpensive spray on oven cleaner, the kind with sodium or potassium hydroxide. Let it sit in the sun. Hose off. Repeat as needed. This also attacks all paint and some platings. Follow all the precautions, but especially wear goggles.
My *opinion* is that bases are much more dangerous for eyes than acids.

To clean the muck off of parts that are made of ALUMINIUM or STEEL, out of the car and removed from the engine, you can use the spray on paint remover that contains methelyne (spelling?) chloride.
With this method I put the part in a plastic bag after spraying, (otherwise the paint remover evaporates too soon) let sit in sun, rinse, etc.
No I badly worded that post. On the valve cover there are two ports. One centrally located, the other is off to the side close to the trans. The central one is where the PCV valve plugs in. From the PCV there is that gray colored hose which then runs over to the intake manifold. On the port by the trans side, there is just a hose that runs to the air box. I didn't change the placement of anything, just cleaned out the valve and stuck it back in.

Cause it was clogged, I believe that the engine was venting crank case vapors through the side port instead of through the PCV.

Yeah, that would be some very very bad mojo........

Hmmm when I was under there it didn't look like that big of a deal to drop the pan, might do it closer to the end of summer before I go. Peering through the oil filler hole the head looks pretty clean, no idea on the bottom end.
