oil pumps

[Dave]

what oil pump is used in the 3.4's?

anyone have pictures of the pump, and it's placement in the engine? (both with the pump attached, and removed)

thanks in advance...

No idea, but why are you looking? Your Z is long gone! :P

Well he caught my attention, I'm looking for a high volume one for when I port my pan to 6 qts and make it ready to rock to 8k.

[Dave]

well, actually, my Z isn't gone, I got totally screwed on that deal, so the car is still in my driveway. (I won't even go into how pissed off I am at that kid in wisconsen)

anyhow, I was thinking about the pumps, and how similar they are to the SBC pumps, or if there's a melling pump out there.

I'd really like to get my hands on one of the pumps so I can take 'er down to my friends at the machine shop and have them peek at it for me, and see what they can do.

How the fuck do you port an oil pan? :wtf1:

lol I knew someone would catch that. Well after it is in a Fiero, I am going to pull the oil pan off. From there, you measure as accurately as possible the amount the factory pan will hold. Then you get happy with the cutting wheel and a welder. And you basically add 1 quart to the overall volume. Then when filling up, it'd be a 6qt instead of 5, of course you'd still have to use the dipstick becuz it isn't 100% accurate. But that is basically how its done.

Well I have an oil pump in the red car I can use, but unfortunately I'm not in CO and my dad probably isn't up to it, cuz it will be a pita.

But they should be almost identical to that of the other 60*v6s, and if I know GM, they will be pretty close to those in a SBC.

I don't know about you, but I've ALWAYS had to put 6 quarts in my DOHC in an oil change. Why are you only putting in 5?

Chris used to have a picture of the 3 60V6 oil pumps GM offered. The DOHC is twice the size of the 3.1 and flows 60% more. I am not sure what the largest pump is that you can fit on the block itself but the pan will need to be modified to go larger than the DOHC...or the pickup will have to be akward. I don't know where any pictures are at the moment though showing the pump on the block. I need to get the server working again here at the house so I can access all of my pictures.

Mine only takes about 5.5 qts. I want to make it take 6.5 including filter.

Yah I'd liek to see those pics. Hopefully this X-mas I'll have time to really looka t it. I will see th efactory DOHC ones, and we have a few SBC ones so I should eb able to compare. Then i could order just an aftermarket SBC one, and adapt it for my use. Hopefully the block and pan will be big enough for it.

[Dave]

the SBC and BBC pumps are the same, except for two things, the BBC (big block chevy) pumps have 12 vanes, where as the SBC pumps have 6, and the BBC pumps have a 10% higher flow then the SBC ones.

I'd personally use a BBC pump because you'll get more pulses per rotation helping to smooth out the oil flow.

[Dave]

any pictures of the pumps yet?

Dumbass, Thats not called "porting" its called fabricating.

The DOHC already has a huge ass'd pump. the Pump that was used in these engines were sold by GMPP as a High Volume pump. I used to have one for my old 3.1L, untill due to the lack of "higher volume Pan" i sucked the pan dry (4L pan on the 3.1L) and seized a Cam bearing to the camshaft which spun in the block ect ect ect.....

If you are making a larger pan Aaron, make sure you do trap doors and baffles to ensure the oil stays at the sump.

[Anonymous]

I know what its called I was just saying that becuz I couldn't find the words

That may have been the reason that I spun mine, is that it ran the pan dry. I wouldn't doubt it, at 7,000rpm that pump is turning pretty fast. So I might be able to escape with the same pump, but I am definately going to refabricate the pan.

I don't know if this will help you out or not, but if you have a local NAPA Store the part number you need for the Oil Pump is #6011759, and the pick up part number is #6011741. Hope this helps you

just remember high volume oil pumps suck horse power. Unless there is a problem with the stock pump not keeping up with the oiling needs of the engine, a high pressure, high volume pump may hurt more than it helps.
