It sounds like the oil pump,in fact,has gone out.When installing the oil pump,of course,the oil pick up tube,screen needs to be inspected,to see if it is clogged up,or maybe cracked in the tubing,or has fell off.In removal of the oil pan,inspect the main,and rod bearings to make sure they are not scored.

A couple of things, either oil pump (most likely cause) or the oil pick up tube has gotten clogged. Another possibility is that several bearings have spun blocking the oil passage (but rarely causes 0 pressure) sometimes it even reads high. I would definitely start with the oil pump and make sure you do not drive it with 0 oil pressure you will definitely damage the bearing, rods, lifters and will most certainely spin a bearing if not already causing low end knocking (or loose connecting rods).

Without inspecting the vehicle its difficult to say for sure ,but firstly put a manual test gauge on it ,the one with a pipe and no electrics ,if no oil pressure then only course of action is to change the oil pump,i honestly dont know whats involved in changing an oil pump on this type of vehicle as to if it can be accessed through the sump of if its bolted on the side of the engine .But as a precaution do not start this vehicle ,only for a quick test of the pressure with a manual gauge .Sorry i cant help as to how to change the oil pump or the oil pressure relief valve because i have never seen one here in spain.Another thing i have seen though on a engine and thats a ball bearing seal plug in the end of the oil gallery drilling pop out ,But?? as stated i have no experiance on this engine

if you are running 5w-30 (recommended) you can go to 5w-20, there is a TSB out that recommends this on early 2000 Jeeps. If it has not been changed lately, it may just be ;'slugged', that is short trips and condensation can affect the viscosity of oil. also the brand of oil filter can be the reason for this, so to be safe do a oil/filter change, use full synthetic and a good oil filter like Purolator Pure One, Wix, K + N, or Bosh, all have anti-drainback valves.

What is oil change schedule for 2007 DTS also transmission fluid change schedule


Your vehicle's engine requires oil meeting GM Standard GM6094M. You should look for and use only an oil that meets GM Standard GM6094M. SAE 5W-30 is best for your vehicle.
The best Brand is 5W-30, Mobile 1 synthetic oil, but you can use Castrol GTX 5W-30, too. It is very important to use only one barand of engine oil.
When the CHANGE ENGINE OIL SOON message in the Driver Information Center (DIC) comes on,
means that an oil change service is required for your vehicle.
If the engine oil life system is ever reset accidentally, you must service an oil change for your vehicle within 3,000 miles (5 000 km), or three months wichever comes first, since your last service.
The maintenace tune ups for this car are scheduled at 25K, 50K, 75K, 100K and so on.
Dealer recomend to change the transmission oil and filter at Maintenace II, at 50K, and the air filter too. Use only DEXRON®-VI Automatic Transmission Fluid.
The dealer sugest to flush the radiator every 75K and use 50/50 mixture with distilled water, and use only DEX-COOL. I recommend to flush every 50K.

I have a 2005 GMC Safari. Oil pressure usually around 40. I just changed oil 5w/30 and filter and now pressure is running at 60+. Should I be concerned?


Heavier oil will increase the oil pressure. keep your eye on the gauge for the next few days & take notice of any change. If so have it checked out. Hopefully it will stay where its at for now. At 1200 miles the pressure should decrease some after the oil impurities are broke down
