What steps are needed to change a high pressure oil pump ona 03 6.0
Possible clogged oil galley, filter, defective oil pressure gage, or the use of an oil that is the incorrect weight. Replace the oil filter with a Purolator filter and change the oil. Install 5W-30 oil. If the pressure is still high then you need to have the oil pressure tested with an accurate test gage, to see exactly what it is.
The AC system will vibrate, and pressure throughout the system will be extremely high.
Low oil pressure.Oil level extremely low. Faulty oil pressure sending unit. High mileage/worn engine bearings.
could be oil is low or in need of a oil and filter change. n0rt
The pressure will be high until the oil reaches full operating temperature.
High oil pressure is good....
There are several oil seals in most vehicles. We need to know which one and what vehicle. More info please.
Oil pumps are pretty durable but Id say if you are having a low oil pressure issue then definately. But a good high volume (NOT HIGH PRESSURE!!) oil pump is a huge improvement over stock. PLUS they are cheap. Id say its worth the peace of mind seeins how you are right there and it only takes one bolt.
A cause for high oil pressure could be related to the type of oil that is being used in the vehicle. Thicker based oils such as 10w40 and higher could cause high oil pressure.
If your oil pressure gauge is high you have to much oil in your engine. Overfilling your engine can result in you blowing out your gaskets.
