GM warranties it's junk pumps for 3 years correct? What is the warranty on the superior melling pump? If the melling engineers have everything figured out and redesigned the pump, they should feel comfortable giving a better warranty than GM, especially seeing that melling will never be covering any labor costs. What is the melling pump warranty?

I'm not sure of their warranty and I'm not saying the pump is superior. I am saying that the Melling pump has improvements to some of the potential problems the oem pump has. Melling's pump still has to fit and function within the design GM came up with. Also the Melling pump, being an aftermarket replacement, is also subject to non-professional installations.

I'm curious, are you thinking there is no problem with the pumps themselves and that all the failures are due to poor maintenance, shoddy installation of various components or customer abuse?

Lol your in the wrong hobby if your looking for rational. I've been doing this for a long time. To end your rational search you don't have to get a melling keep your warranties GM pump and stop steering the OP's thread into a debate. Yes the melling is superior that's a FACT, no not all GM pumps will fail but their record has been documented since 1997 since the Ls1 and its basically the same damn motor with bigger bores ALL of the LsX's. The OP knows what he's doing, you don't come across like you do.

There are a million chrysler k cars still running and driving around...it doesnt detract from the fact they are complete pieces of cheap poorly engineered shit.

All it means is that there are a million buffoons who are willing to change a head gasket every 6 months.

Lets get back to to the much much higher count of people with oil pump problems, vs the one random slick50 golden poster child.

I mean, is the one person born with a 3rd nipple a super hero, or a freak?

There have been more problems with oil pumps alone in my short time on this board alone to know there is a quality issue, and possibly a bunch of other issues compounding it like mentioned earlier.

For scientific purposes.. Someone should open up another oil pump and see if there is any scarring similar to the OP's oil pump. Specifically one that hasn't been taken off and put back on. I'd like to volunteer mine when I proceed with the heads/cam swap later this year.

When my LS3 pump went out I had several excellent tuner shops in my area tell me to go to the GM high volume pump over the Melling. I'm sure it was personal preference but I went with the new GM pump. No issues.

What GM high volume pump is that? You got a part number? Thanks

Had a chance to take a look at the lifter, it seems to be intact so i'm going to put the valve cover back on and let it run for a while, perhaps I'll get lucky and it will pump up.

Awesome. Not many people see the incredible value of having one of those.
I bought one on ebay used a few years back and it's invaluable.

Good man!

One of my biggest ls engine bitches is that you have to pull the heads to remove lifters. That thought frustrates the hell out of me.

I've been messing with it all morning and it seems it's not going to pump up, i just started pulling it apart. The good ol days you would pop the intake and be all set, pulling a head for one lifter really sucks but it's the way it is i guess.

litle88 · 04-18-2013, 07:31 AM

CFD, can you push down on the lifter with the pushrod? Is it easy or is it pretty stiff?

Cool pics man!! I'm with POS, those are handy!!!

I took a length of steel rod and ground the end to the shape of the pushrod and tried depressing the lifter plunger but it is stacked solid in the lifter, it's not worth screwing with anymore, starting it more could result in more damage or the lifter coming appart so i'm gonna pull it appart and end the misery. lol

That's the best route to take, I'd go that way too bud.
