Harley works off of high volume not high pressure. don't be alarmed!

SOURCE: low oil pressure at rocker box

The Ironhead Sportys have a tendency to do this when the Gerotor Gear Set is worn. These are the thin set of drive gears in the oil pump. HD Part # 26492-75. Do you have a problem WET SUMPING? This is when the oil drains from the reservoir into the crank case if the bike sits for a period of time and when you attempt to start it pukes oil from the breather tube. If so you need to check these gears. Gerotor Gear Sets inner/outer clearance should be .000 the shaft should have a clearance of .0005 and the feed gear height in the pump should be .011. Normal operating pressure when hot should be 4 psi at idle and 10-20 psi at 3500 rpm. The pumps generally have issues before the rocker bushings.

SOURCE: i have a 1980 harley

oil pressure loose can be due to crank bearings and rod bearings, have the clearance's been checked? also have the oil passages been cleaned with a wire brush (they make special brushes for this) and compressed air blown through them? if u have not done the above do it, there is not any short cuts for this type of problem

My truck loses oil pressure after motor gets warmed up, then if i shut off the engine off and start it back up the pressure goes back up for afew miles then goes back down again


Hi Jasmine:
This sounds quite typical for an engine that has a lot of miles on it.
Doing regular oil changes including changing the filter is important.
Using an oil like 15W40 is appropriate.
If the oil pressure drops below 40 PS at driving speeds you might consider trying to extend the life of the engine by using an additive like STP when you do the oil changes.
Hope this helps.

Low oil pressure and small leak


Oil pressure on these bikes is around 30 PSI at 2500 RPM or higher when fully warmed up. This will take 20 miles or more. At idle on fully warmed engine, pressure can be as low as 7 PSI depending on oil quality. It should however increase to around 30 when reved up. You did not specify where your oil leak is for me to comment on.

2006 chevy 2500 express cargo van .What is a good oil pressure for this van. it has 150,000 miles runs great


60psi cold / 30-45psi warm is ideal. I've seen (with that mileage) 45 cold/ 20 warm and that's acceptable - anything less start thinking about a new oil pump.

My car is Volkswagen polo 2001 1.4 automat. After driving 8-10 miles at a low speed(30-40 mile/h) oil pressure warning appear at the dash board. When I push the accelerator the oil pressure warning...


Do not assume that the low oil pressure warning is a false one or that you only have a faulty oil pressure sensor. Your engine may in fact be running with low oil pressure once the oil heats up and thins out. 8-10 miles of running is enough to get the oil hot. It is significant that you only get the low oil pressure warning once the engine oil is warmed up.

If the oil pressure in the engine is low, engine lubrication will be impaired and the engine can be badly damaged so you need to run an engine oil pressure check.

1. How long has it been since you have changed the oil in the engine? If it has not been changed in the past 6 months then change it and change the oil filter at the same time. You must only use the oil specified by VW for that particular engine.

2. When new oil is heated it thins. If it is old and contaminated it will be even thinner when warm. You will get less oil pressure when the oil is thin and hot and more oil pressure when it is thick and cold. Fresh new oil is a little thicker as it has not been diluted with petrol and other contaminants.
Oil pressure also varies with engine speed (RPM). At idle or low engine RPM the oil pressure is lower.

3. OIL PRESSURE CHECK
After the oil is changed the car needs to be run to check if the oil pressure warning still appears. (I suspect that it probably will). If it does appear then an independent oil pressure gauge needs to be connected up to the lubrication system in the car to check the engine oil pressure. This is best done when the engine oil is hot because this is when you are getting the low pressure warning. Any competent mechanic will be able to do this. ( The useless ones will not). The oil pressure can then be properly checked on the gauge at various engine RPM. If there is a low oil pressure reading from the gauge then there could be a problem with the oil pump, the oil pick up or the oil pressure relief valve in the engine.

4. You mentioned that you see the oil pressure warning disappears once you accelerate. I suggest this is only occurring because with an increase in engine speed (higher RPM) the oil pump speed is increasing and the low oil pressure problem is being overcome temporarily. However as soon as the engine RPM drops the oil warning will appear again which means the engine is running with below minimum oil pressure at that RPM.

Even when you get no warning, the oil pressure in the engine could still be running significantly below the optimum level.


5. It is possible that the oil pressure is fine and that the problem is an electrical gremlin as these cars suffer from a variety of electrical faults. However from what you have described I think there is a problem with low oil pressure in the engine and until it is properly checked it is unwise to assume that you are just getting false oil pressure warnings.

I hope this helps.

1992 honda accord 245,000 miles oil light blinking while idling and once while I was driving the oil level is good. what could be the problem


Oil light relates to oil pressure, not oil level. If engine has not been rebuilt, it is safe to assume that it is nearing the end of its life. Low oil pressure light goes off on increased rpm´s , and hence, pressure goes up. You can extend the life a little bit by switching to heavy oils, such as 20W-50, but eventually it also wont be enough, and will start fouling the plugs. Check the oil level, because extremely low levels of oil can also produce a low pressure warning.

Oil pressure drops to zero after warmed up or below 2700 RPM


Check the oil pressure with a test guage, if the finding are the same, the look at your oil filter, pump, pickup, or pressure relief valve.....

Oil light comes on and "bings" when the tack shows 1000 rpm.


I have no idea how many miles are on the van but 1st lets talk about the oil lite, it is telling u that the engine has less than 10 PSI of oil pressure, this may be the pressure sending unit on the engine is defective, if it does have low oil pressure then severe damage to the engine bearings can result, the click is most likely the contacts in the starter solenoid are burnt, they act up more cold and give the click you hear. I have no idea about the steering issue, without hearing it is almost imposs to diagnose such concerns. In closing I highly recommned that you address the low oil pressure concern ASAP

Oil Pressure Drops While Driving


your oil pump is either weak or there is sludge i9n the oil pan. my adives is to have the oil pan dropped . chances are sludge is the culprit. as the oil get's warm the pressure should only drop slightly but pressure is generally dictated by engine rpm. pumps are gear driven so if it was a bad pump your oil pressure would start out very low at start up.
