Driving home from work this evening (Seguin to SA) I noticed a click sound followed by a loud series of taps as my 2010 Sierra Z71 would go from 8V to 4v. Oil pressure eventually dropped to zero, idiot light came on (low oil pressure) so I pulled over and had it towed home. Considerable engine noise (loud taps) when I pulled it over.
I had one bank of lifters changed out last summer. When that occured it was mostly just loss of power without the issues that occurred today. The machanic who did the lifter work at the time told me that it was a matter of time before the others would go out.
Truck just turned 200,000 miles last week.
Any ideas on what I'm looking at? Lifter replacement? New engine? Sell it for scrap?
