No, you cannot. If it has locked up due to no oil, then you are looking at a rebuild, and maybe even a total engine replacement because of the nature of the catastrophic failure.

No oil means the bearings had no lubrication, which chewed them up, as well as the crankshaft journals - Cam lobes, and maybe the connecting rod came apart and busted a hole in the block?

You could price a low mile motor from the same car at an auto recyclers - would be the best and cheapest way to go as long as you have a good mechanic that will thoroughly inspect the replacement motor before it is purchased and installed.

Good Luck.

I have on oil psi put in a new oil psi sensor and new oil pump and still when you rev the motor you get 18 to 20 psi what could it be


Hello, This information is from the 1995 cadillac 4.6 Northstar service manual: oil pressure specifications engine at normal operating temp at idle 5 psi at 2000 rpm 35 psi Based on experience you would be better off putting another engine in your car. You can not turn the crankshaft on a Northstar engine. It sounds like the main and connecting rod bearings are worn beyond specs and also the cam bearings. You would spend more on parts compared to cost of another engine. That is my recommendation.

Hi, please can you tell me what is the different between the 1993 northstar engine's oil pump and 1998 northstar engine's oil pump? thanks in advance


If I remember correctly it has somefhing to do with capacity. The best way to find out is check with a GM dealer to see if the part number for a 1993 is the same as a 1998

I have a Cdillac Deville 98 northstar. Getting an Error message - Engine overjeat, Change Engine oil, Check Coolant level and later I get Idle engine message I changed engine oil and coolant recently -1500...


Whatever you do, NEVER allow this engine to overheat and always use the correct antifreeze (DEX COOL) or you will damage your heads severly. The heads were made from aluminum so there is a very serious warping issue on the 1998 Cadillac Northstar engines. There should have been a recall but wasnt, ended up costing me 3 thousand USD to fix the engine problems I had but she now runs fine. I only had the car 4 months before this happened so someone prior to me owning evidentaly let it overheat on too many occassions and I had no choice but to fix cause I was still paying on the car!! Good luck

Overheating engine, no leakage, some white smoke when cold,


1 st drain the oil if excessive for it will just aggitate in the oil pan and it will not pump through the oil pump resulting in internal engine damage. The belt should be replaced every two years on any Northstar motor. A tune up is also recomended as well with high milage

Replacing the thermostat on a cadillac deville


Assuming you have the Northstar engine....

The thermostat in the northstar engine is located at the bottom radiator hose (unlike most conventional cooling systems), the hose connects into the housing where you will also find the water pump.
Remove the hose from the housing,then remove the two bolts on the flange,the thermostat can then be pulled out.
Take note of the orientation of the thermostat as you remove it.
Don't forget the new gasket when you install your new stat.
