Why would the oil pressure in your 94 ford tempo be high and coming out of the valve cover breather filter?

If your oil pressure is actually high, ( oil pressure must be tested with a mechanical gauge) it could be the pressure relief valve sticking. This is very unlikely the cause. Depending on how much oil is coming out of the breather, it could be one of two things. If it is a small amount seeping through, check the PCV (positive crankshaft ventilation) valve. It is attached to a hose and goes into the valve cover. Make sure the valve is opening by starting the car with it out of the cover. You should hear it opening and closing
If it is a lot of oil coming out of the oil filler hole when cap is off with smoke you have excessive blow by. Blow by is combustion gasses entering the crankcase.
The combustion is getting past the piston through either broken piston rings or a damaged piston.

How do you fix oil in air filter on 1990 jeep Cherokee?
Clean the orifice tube at the valve cover. That's the tube that goes from the valve cover to the intake. At the valve cover it gets plugged causing crankcase pressure to get fed through the breather tube.
What is a breather hose?

What is the hose coming out of the top of the passenger side valve cover - opposite side from the PCV valve - leading to the air intake line on Chev 5 liter V8?
These are breather tubes. On older models there is usually a breather filter in its place. On newer cars the engineers removed this filter by placing a hose connected to the air duct. (Since this air is already filtered)
Where is the breather filter located on a 1989 Mazda 323?
I am not aware of a breather filter on the 323. The breather hose on the valve/cam cover vents directly into the intake snorkel located between the throttle body and the air meter (the snorkel is the black oval shaped tube in the shape of an 'L') Cheers Malcolm
How do you change the air filter on a 2002 VW Beetle 2006?
To change the air filter on the 2002 VW Beetle, just remove the air breather cover by unscrewing the center nut. Then, remove the filter and add the new filter in its place. Place the cover back over the filter and replace the nut.

What is a breather?
A breather was a metal incased filter than pushed into the valve cover on older engines.Most had a rubber hose connected to the air filter canister and allowed the vacuum to pull out any cylinder blow by trapped in the engine crankcase. It help with ring sealing/ emissions and pumping loss to a certain extent.
Why is there oil in air box on mercury topaz 2.3 liter?
The oil is coming from the breather tube that comes from the valve cover. There is supposed to be a filter that will block this, but alas, they sometimes do not work to well. One way to stop this, if it is a big problem would be to put a little batch of steel wool in the breather line at the air box side. This might help. Or, replace the original line and filter. As long as there is not too much oil getting in there, the car will still run fine.
How do you install air filter for 1989 GMC vandura?
I've found no other way but to remove the doghouse and get it from there, but check the breather filter while you have the thing apart and replace it too. If the filter is not that old you can reach in from the engine area and remove the cover and turn the filter a quarter turn instead of replacing
