Steve answered 6 years ago

I have a 2008 Chevy tahoe LTZ that the oil pressure at start will be about 20 then will go to 40 at about 2000 rpm but then abruptly drop to 0 and lights go off for a brief second then pressure goes back to 40. This just started when weather started getting below freezing. Checked oil level it is good and I still have about 1500 miles before it is due for oil change. Is this a oil sending unit issue or what? Well sensor was changed screen cleaned under sensor. Still setting off code. Dealership saying I need new engine. Engine has plenty of oil there are no new noises......belt makes a clicking noise as it turns, but no other noises that are not normal. I took it to a dealership where my wife works...not real sure i trust them now. Any ideas now?
