Default stock oil pump pickup, a closer look.

i just got this one from the dealer and besides being burned to a crisp, i noticed how tiny the inlet is! a postage stamp covers it with room to spare. the support is also paper thin. i have a hard time believing that this can keep up with the demand of a 12mm pump and thicker than stock oil. it also has nearly no clearance to the bottom of the pan. i know the tubing is also pretty small, but the tubing doesnt have sharp edged sheetmetal covering it like the pickup does.

Find a used older motor and steal the pickup tube.

I'd rather it be submersed in oil, rather than picking up air due to lateral gs, especially with a higher volume pump. However, that inlet is quite tiny.

I'm not sure what your argument is with regards to oil weight, though.

thicker weight oils and high volume pumps need more pickup clearance, cold thick oil and tight pickup clearance could potentially starve the pump if its too tight. and thats not just me talking, thats strait from moroso. sure it may be an extreme case, but to me i cant imagine ever having a problem with the pickup 1/2" from the pan. i dont think its possible to suck air at 1/2" unless you are 3 qts low and autocrossing.

I could see that as an extreme case. not trying to knock you just curious.
the pump will start start drawing more of a vacuum at its suction, you'll have a greater differential pressure across the pickup tube and oil will flow

What other options are there for an improved replacement oil pickup? If none, we need to hit Moroso up to offer the oil pickup separately from their oil pan.

Unless their pan is exactly the same depth as the stock pan I would rather make the pickup myself to control the clearance between it and the pan I pick to use. I seriously doubt all the stock pans are within 1/8 in depth of each other and I found on the stock pans we had the depth varied a lot. On a new 04 usdm sti pan and pickup there was about .187 clearance before we cut the lower shield off of the pickup. With a 12mm pump I am happy with a clearance of .437 or 7/16. This will require either changing the pickup or the pan. I always build our own pans so I have been reinforcing the pickups, cutting the shield off (cutting the shield off gives some added clearance) and making the pan to the desired depth to accomodate the pickup and the extra clearance.
It seems to me if you can't or won't build your own then moroso might be a good choice.

Maybe you could produce these pickups, there's definitely a market for them. I just can't swing the cost right now for the new pan, my build is already costing enough. Maybe I can hit up my fabricator to just modify a stock one.

I think we should all be concerned about this, especially when building a motor. I wonder what percentage of engine failures due to oil starvation were caused by this issue.

I would like to do 272 cams but I'm now thinking I'd rather put my $$ into engine failure prevention, like the Moroso oil pan setup than more power. I wallet could not recover from another engine build after this one for awhile.

It would be interesting to see if the pickup tube has been further revised for 08 STI/WRX.

Anyone can check part # ?

anyone have a link/write-up to removing/replacing this? sounds like no one makes an off-the-shelf upgrade? just gotta do something custom?

If not an 08 sti pick up, maybe one off an s204 sti. I'll hit up japanparts.com or AVO for this.

Graham, can you quote SOJ part numbers? Based on the diagrams they look identical to what we get here in the US. Both, the earlier and later design are prone to failure, although the earlier one seem to be most common.

I don't have a jdm block.

The fact that the pickup tube goes into the block on all the subies I have means the od of all the tubes where they go in the block is the same. It measures about .700 OD. The tube is larger on the outside of the flange and is about .780 give or take about .010.

Unless the 12mm pump block (jdm block) is different the pickups are the same diameter.

The screen and cup and shield or cover may be different though on the jdm version.

The block gallery from the pickup to the pump would need to be enlarged to be of benefit to go along with a larger diameter pickup tube.

Also those two different pickups appear to go to different locations in the pan. The supports also appear to go to different windage tray bolts.
