I bought the monte used with 15,000 miles and at 16,986 low oil light came on car was not low on oil just low oil pressure 3 lbs at ilde dealer said cam bearing spun in block was told to put new engine by tech. support

 

Right, the low oil pressure caused the cam bearing to spin.
But what caused your low oil pressure? It's not a very common issue on these engines, let alone one with 15k miles or so.

-Riggs.

 

The dealer told me they had a bad batch of oil filter adapters machine work on bypass valve,3,8 engine they changed my adapter . A NAPA big shot told me gm bored some 3.8 engine cam shaft off center by accident.

 

I think the key message to follow here is "TURN ENGINE OFF". Hopefully you have a bad sensor that incorrectly "thinks" the oil pressure is low. However, it's also likely that the oil pressure is low - and driving the car with low oil pressure will destroy the engine. I would have it towed, not driven, to a shop for diagnosis if I didn't have the necessary tools to diagnose the problem in my driveway.

 

ok lately my engine keep turning completely off on me while im driving, it did it to me three times on the express way i been lucky to be able to pull to the side of the express way all three time with out causing any traffic thank god for that.....but anyways when the engine shuts off on me when i try to crank it back on there is no turn over it dont crank at all but all the lights switch on but no turn over or crank , it usually take me 4 tries before the car can crank back on again.....can someone please explain what that problem could be , someone told me it might be my ignition going bad but i want to make sure....

 

oops i forgot to say the car is an 2002 monte carlo ss, and the engine keeps turning off on me while im driving , please someone tell me whats going on with my engine thank you....

 

Search for "crank position sensor" on this site. Might help.

 

Ok, I got a new oil pressure sending unit from Auto Zone and replaced it. The problem is gone now.

 

Bro... your oil level is not the problem. Better make certain that pump is pushing that oil around? Blow that motor because you didn't take it in to have the codes pulled so GM could service it, and you're SOL... (They won't honor a warranty for driving without oil pressure)!
