Oil pump or sending unit?
2007 Chevy Avalanche
Oil pressure dropped to zero while driving, started dinging
and check engine light is also on. Stopped driving
immediately, engine sounds great, no noises or knocking.
Checked oil, oil is full and good. Start the car up and oil
pressure is normal for 5 or so min, then drops down again.
Have since drove about 20 to 30 miles in short trips. Still no
odd engine noises. Just wondering what is the problem.
Truck has about 62000 Miles on it.
Chevy dealer is picking up tomorrow, just curious what
people think it is, I wanna know, before worrying for the
next couple days
