Oil guage read 0 - turned off truck and bad main bearing

Asked by Oct 11, 2015 at 07:21 PM about the 2006 Chevrolet Silverado 1500

Question type: General

2006 Silverado 5.3 with Z in the VIN.   108, 356 miles on it and have owned
since new.  Treated better than most parents treat their kids.  Ran about 170
miles and stopped to get prescription at a drive thru window and shut off the
truck.  Immediately when restarting the oil warning light came on so I pulled
out of thexRe and into parking lot.  Bad main bearing according to dealer.  
Question is what does the pressure need to be before the dummy light comes
on?  Thanks

That is for VW but should give a general idea. I don't have any information on GM and the parameters set in the code for oil pressure.

Usually 4PSI and under will trigger the light. HTH. -Jim

4PSI in my mind is way too late for a warning. Drove 100 ft and rebuild or replace according to dealer. Oil pump failed and the main bearing is pretty chewed up. In the early years I depended on the oil percentage and then switched to every 3000 miles using high mileage oil. Dealer wants $7100.00 for crate and $5100.00 for an engine with 81,000 miles on it. I am torn as what to do as this is the last truck I planned on buying. Have only put on 61,000 miles since 2008 when I was able to work from home. That is 7 years 61,000. Crazy - any recommendations... I am checking with local auto repair shops for a lower price. Just really ticks me off this has happened.

You may be ok. Did you hear any engine noise, knocking, ticking to indicate low oil pressure? If not I do believe there is a screen basket under the oil pressure sending unit that gets full of sh** that needs to be cleaned. Screen gets full of crap not allowing the oil pressure switch to read properly. Cheap Check...

Rowefast is correct. There's other causes for low oil pressure. You will also hear a bad bearing in most cases. Usually what happens is you have an oil pressure problem long before the engine starts knocking from bearing wear. With GM today, who knows, 108,000 miles is not inconceivable to me for a bearing failure. But I am suspicious. Get another opinion. Could be a simple bad oil filter, or pressure relief valve that's stuck. As I said, bearing failure is usually preceded by the long standing oil pressure problem. Not an instantaneous one. HTH. -Jim

Thanks for your help - no noise that I ever heard that would tip me off that something was wrong. The dealer showed me the main bearing that was chewed up pretty good. Truck is back at my house now going to have used motor put in from a local shop wth a 3 year 100,000 mile warranty.
