That's probably the first thing you should do.

Yep, it was your thread. I'll say this, a factory pump goes a long time before needing to be changed. if I ever have to put a pump in any ls motor, it will be a factory ported unit. same goes for head gaskets. I used aftermarket once, and I had one give out. i now have factory ls9 gaskets and more boost and they are holding just fine.

If I find that thread on the melling pump, I'll post it.

Melling serves the global transportation original equipment and aftermarket segments

GTO1_OHIO Oh bull about avoiding a Melling. With any aftermarket oil pump or any aftermarket part in general, you just have to select the correct part for your application. With a high pressure or high volume oil pump you just need to know which to select because you have many options. And you need to consider how it will affect your oil pressure. Many are just ported LSx OEM pumps and rebranded. The OEM LSA pump will also just bolt on and has much better flow then our OEM pump.

The heads don't have to come off to swap the cam, but it sounds like you want to tear into her any way. Have fun!

No they didnt. Im not sure how long that would have taken to happen (ran less than 30 seconds after drop)but i feel like they always make some noise. Ive wanted to give it a little more power and after i bought a DD i feel its time to freshinin it up and make it a little more fun for the days I drive it, which will be back to daily except the winter.

sending unit fails, giving a low reading

or the oil pump pickup oring is leaking

I'd hate for you to band aide it and not correctly fix it. I'm definitely not a fan of melling oil pumps. Factory pumps are usually better. My buddy had this same issue and pump a high pressure pump and it masked the problem for a while but came back...his cam bearings are worn.

Kfxguy As far as cam, if you want something mild that makes good power, texas speed 218/224 or the summit stage 1 ghost cam 222/233. But you need to make sure its actually the pump.

PsychoTeddy Texas Speed recommended these when i called to bother them, first time in 2 years this car has let me down, that includes 900 miles on a shot center support bearing

maradamx3 The stock heads flow pretty good but the tiny cam in the goats don't take advantage of that flow potential. If you don't want to get too invasive, throw a bigger cam in it and enjoy. But, since the heads will have to come off, prime time to do something with them too, but be careful, the budget can get eaten up quickly. Lots of options.

06 LS2 Goodbye Oil Pump, Hello what?

So i have a 06 header back, suspension car, with a built T56, 1 piece driveshaft. and a few other small things.

My oil pump gave up this morning... I pulled it back up my driveway and shut it down. Obviously I need to go Melling High Volume Oil Pump but what next.

Might as well do a cam, whats the point of that without Heads. I was looking at the Texas Speed Head and Cam packages. Any suggestions on of them? or other?

https://www.texas-speed.com/c-3237-c...-gto-2006.aspx

Other things I need to check or replace?

Id like to spend around 6 or less getting it back up and going.

Thanks
