20k mile LS3 oil pump failure
like the title reads, my 2014 1LE camaro lost oil pressure while I walked away from it for 5-6 minutes so it could warm up in the cabin sunday night.
went back outside to the car expecting a warm welcome..
alarm and Dash was lit up saying "zero oil pressure, shut off engine immediately"
tearing into it tomorrow. I really thought GM would have fixed this TSB on the ls3 oil pumps by now
This has been a stressful week because of this. my cars are my only toys I get to enjoy and none of them run right now
I have a Melling high volume pump and ls2 damper on hand in case things are okay in there. I can't imagine the engine getting hurt too bad. The oil pressure was fine when I walked away from it so It couldn't have idled for too long like that.. It wasn't knocking either
wish me luck guys. I really did not want to be spending money on a 20k engine rebuild. Not because I can't pull it off. but because it's going to get expensive because I'll be wanting to upgrade parts

The cammed and headers/tune part would deny any warranty work with my dealership even if the parts did not cause the failure. I could make a big deal about it but I needed it fixed.
The oil looked great, no abnormalities. I used a customers lift at his shop and I took a good 5 hours with a GM tech friend of mine swapping the oil pump. (Electric power steering motor) was in the way. Backed off the K member bolts slightly and suspended the transmission higher to pull the engine up from the K member. this allowed us to drop the oil pan low enough and reach the oil pump pickup tube bolt. From there I swapped pumps and removed the ls3 chain tensioner and put in an ls2 chain damper.
90 miles later all is good. A little better oil pressure than stock. My oil pressure doesn't drop below the 30 mark on the factory gauge pod. (2.9-3.2 bar)
I got lucky I guess.
I will be doing the trunion upgrade soon after i take care of my clutch pedal sticking problem.
On a side note. The stock pump pressure relief valve was stuck. (Little piston thing) no idea why GM has not fixed that issue. It's been a TSB since 2011
