The only reason im not changing mine out with my cam is because that's what the word on the street was, but if anything does break after my cam i will be going melling for sure. Sometimes its good to own an automatic! Lol

Hey it's not an early 2010 anything! Those were just internet rumors stock Ls pumps have been failing since 1998!
Yes there have been NO L99 pumps reported. YES the flow more volume needed for the VVT and DOD. We L99'rs use 8qts of oil lol.

I swapped out my good L99 pump for a Melling when I installed a cam. The L99 is ok but a bunch of folks had issues with the LS3 pumps even stock. I personally think it's an installation issue even when installed in the factory. This is the main reason they fail.

For some reason the L99 pump can handle more misalignment on the crankshaft therefore they don't fail.

How do you install a pump wrong?

Here is the proper way to install the pump using feeler gauges to make sure there is enough clearance.

I had an oil pump failure last month and reported it here there is a thread my is an l99 my oil pressure would be low at idle like 10 or 15 psi and was noisy like lifters except coming from the pulley area dealer at first thught it was the lifters replaced under warranty

I install pumps with the bolts just finger tight, spin the engine over by hand two rotations and then torque the bolts down. My LS3 takes 8qts dead on the money BTW.

Really?! I picked up my GM HO pump this afternoon for my replacement. I chose not to go with a Melling because I had two of them go out on me years ago; 1 on my 01 TA WS6 and 1 on my 96 Z28 LT1. Both were modded motors built with Mellings. There wont be a 3rd time.

And I thought that was an L99 thing! I didn't know Ls3's took 8 quarts too lol.
I've done the pumps the same way myself But only Mellings.

I went with the dealer's advise, at least it's warranted
Given a choice, go with high volume, not pressure.

Sorry but I'd rather be on my own!
The Mellings are blueprinted and are made of better materials. That's the reason your valve relief was stuck open/closed because of the materials. But yes I agree use the high volume one ie 10296 and it comes with a high pressure spring if you'd like.

My stock pump was so tight on one side of the crank, I couldn't stick my thinnest feeler gauge in there. This causes friction which can lead to possible valve relief getting stuck. Either the pump was slapped in from the factory or it shifted over time.

Loolks like I may have lost my oil pump on an L99. Just about pulling into my shop I lost oil pressure and the valve train started getting noisy. Checked oil level, all is fine. Going to try to make some room in my shop today and get it in so I can check it out further. I'll keep everyone posted on my findings once I get into it.

What is the difference in materials used between the stocker and the melling?
Are there powder metal gears in the stocker and machined steel gears in the melling?

Anyone look at their old failed pump to see what physically happened?

My understanding is that the Meling uses better quality components, as to the gears specifically I am not sure.

The most common failure is the pressure relif valve hanging up but it is common in the LS3's and relitavely rare in the L99's

Litle88 called melling and actually got a detailed explanation of what makes their OPs better than OEM, and he posted it in another thread. that explanation is what sold me; that and the fact I couldn't Google failure rates. I'm sure he will chime in.

Thanks.

If it was gears phycially breaking my thought was going to be crank harmonics even though an oil pump on the crank snout as a WHOLE would serve to help dampen them. I was thinking the crank gear/pump gear interface was pounding itself out.

Stupid relief valve? LOL what a dumb thing to ruin the whole deal.

Hopefully it doesnt happen to me!
