Re: high oil pressure reading?

If you have that high an oil pressure then there has to be a problem. Several items should be checked. First, change the sending unit for the guage. Simplest and easiest and if it is bad will give erroneous readings. You can also replace it with a mechanical guage to see what you are actually getting. Another item to check is oil viscosity. If you are running a heavy weight oil you will get high readings. Next it is possible that the oil bypass valve is stuck closed. This regulates oil pressure and if it sticks closed you will have high oil pressure readings. Finally, make sure that the oil filter is not plugged. This can cause high oil pressure. Not likely if you change oil routinely but it is a possibility. Good Luck and welcome to AF!
