Question about 2005 Harley Davidson FLHTCUI Electra Glide Ultra Classic
Hi James, start by checking oil level in tank and it is between the add and full mark. With engine at normal operating temperature 180-230 degrees and the use of a 10 micron synthetic media oil filter, oil pressure will be 30-38 psi at 2,000 RPM and 3-5 psi. at idle. The oil pressure light is designed to come on at 2 psi. or less. To accurately test oil pressure remove oil pressure sending unit and install known good oil pressure gauge that reads 0-50, there might possibly be some plumbing required for hard to access points. If you are out in the middle of nowhere and there is no cell phone service and your oil pressure gauge isn't working and your oil pressure light is burned out, despair not, you still have one last line of defense left HYDRAULIC LIFTERS.as long as those tireless workers are quiet, you have oil pressure, maybe not much, but enough to get you down the road at a slow to moderate speed using the least amount of RPMS as nessary. Good luck

SOURCE: engine oil plug
Another way to locate it, is with the bike on the kickstand, look underneath of it from the right (brake) side. The oil drain plug is on the front of the square looking pan under, and to the rear of the engine. The oil drain is the plug on the front of that pan, on the left (shifter) side of the bike. The trans drain is on that same square looking pan, but towards the right side, and faces down. It screws in and out vertically, whereas the oil drain is horizontal

Your '98 Evo motor is what they call a "head breater" engine. This means that the crankcase ventilation is at the upper end of the heads rather than way down at the lower end of the engine like it used to be. They the first year for the "head breaters" was 1994.
Now, At the top of the heads where the rocker boxes are, there are three pieces. The lower rocker plate with the rocker arms in it, the middle piece and the upper cover. If you take the four bolts out, you'll see an umbrella valve in the middle piece of the rocker boxes. This valve is a replacable rubber piece. Over time and many times of heating up and cooling down, they can get brittle and allow a lot of blowby resulting in oil in your air filter element.
Now there is another part in the cam chest that has a lot of effect on the operation of the crankcase breather system on your bike. This part is called the "breather gear" and is located down in the cam chest to the rear of the camshaft. In you bike, the part is made of plastic if it's the original part. I have seen the teeth break off of the drive gear and the breather gear stop turning. This will screw up the "breathing cycle" on your engine and cause it to "blow oil". Usually, the oil pump locks up when this happens due to the plastic teeth getting in the oil pump but not always. If this eventually turns out to be your problem, have the mechanic or yourself install one of the new S&S reed valve type breather gear replacements. They don't turn at all and work absolutely great. The part is about a hundred dollars but it's well worth it. Solves the old broken breather gear problem that has plauged the Evo engine it's entire life.
There are no "screens" in the Evo engine other than the "tappet oil screen". Just in front of the oil pump is a screw plug that is in the engine cases itself. If you remove this plug, there is a small spring and cone shaped screen that filters the oil prior to it going to your tappets. This should be cleaned every other oil change but it has nothing to do with the oil in your breather.
Now some riders will tell you that if you allow your Harley to sit for any length of time that it will "oil sump" with you. By this, they mean that oil will seep past the check ball in your oil pump and pool up in your crankcase. When you start the engine up, oil will be blown into your oil filter. Not true on your Ultra. The bikes that will oil sump are the Sportsters, Softails, Shovelheads, or any bike that the oil tank is higher than the oil pump on the frame. On your Ultra, the oil tank is on the bottom of the transmission. Your bike will not "oil sump" unless you have a sheared key in your oil pump or the oil has somehow learned how climb. You oil tank is below your pump in other words and oil does not flow uphill.

camplate check valve sticking,good time for an upgrade SEcamplate,hydraulic camchain tensioners,high volume oil pump,comes as complete kit for about $420. add another $150 for adjustable pushrods and never worry about it again,or replace the existing component youd save maybe $180 bucks but youll be back
thats why they changed the camplate and tensioners in 07, I just did the complete conversion on an 02 heritage it costed with labor about 1100 in your case your looking at 7 to 800 dollars just to get you going for another 30 or 40,000 miles or less and then do it again Im for a 1 time fix myself

No oil pressure isn't good. Sounds like an air bubble may of got in the system. Try this to prime the oil system after an oil change. Pull the spark plug wire off the plug. Now turn the motorcycle over and see if you can prime the oil system. This should cycle the air bubbles through without harming the engine. If that doesn't work, try draining the oil again, and prime before you start. If none of that works, your oil pump may have fail.
