Take the o-ring to the hardware store. If they don't have the right size they can likely make one for you.

Super pickup...

When I used to have an oil pick up tube I would always use a new O'ring and a little fuji bond, you can't be too carfull with that one.

Mach V http://www.fastwrx.com will be stocking these soon.

The improved tube section is over 3 times the thickness of the stock tube, it's tig welded at the flange and since it's made from a stock pickup the fit and functionality are the same as from the factory. I have one in my car and worry no more.

After putting any pickup on my motor I always put tape over the inlet and use modelers clay to check the clearance between it and the pan. You will be surprised at the variances on the clearance. Especially if you've ever jacked the motor up by pushing on the bottom of the pan.

Charliew, I was concerned about that as well after a few had told the that thier factory one was rubbing the pan. The pickups (that I've made, see post #14) are a wee bit shorter than factoy ones to accomodate that scenario.

Charliew I believe that variance in pan/pickup depth is exactly why Moroso included a pickup tube with their pan.

IMO the Cosworth is a better unit for the price. The Moroso only holds 1/2 quart more than stock. Don't get me wrong here, I typically like Moroso components and that oil pan sure is sexy, but their pickup looks like it was fabricated by drunken sailors.

jigga I have no idea, but I do know that both of them have incompatability issues with certain manifolds. The factory pan is quite good, and IMO if you don't see a lot of track time there is no reason to change it.

good golly!!
they want $229 for essentially sleeving (outside) the factory tube...no bigger but just stiffer. I'll bust out my tig and 3 strips of steel and welding them down the sides

Ok, but really I'm already working on a larger pick-up. so ignore me

I've said this before, but just for fun here goes again. There is no point to having a larger diameter pickup because the pickup is not the smallest restriction in the oiling system. Having a larger diameted can or tube only adds more volume of oil into the pickup and out of the pan, where it should be, increasing (marginally) your chances for oil starvation. The can itself cannot be made bigger because there is just no room to spare in the bottom of the pan. Subaru added the "restriction" to the bottom of the can (04-05 STI and ALL Impreza/Legacy models from 2006 and on) with dimples because the can is so close (and sometimes rubs the bottom or sides of the pan) that there is potentially a risk of sucking against the bottom of the pan creating a restriction.

If you're going to mock one up yourself just keep in mind that there are good reasons the Subaru engineers made this part the way it is. They fail because of a manufacturing process defect not a design flaw.

Yes, manufacturing killed that newer age pickups that have plagued a few...and the tolerance between the pan and pickup are too close (hence your dimple explanation)...those are both common knowledge.

Now for my comment: sorry, when I said larger I wasn't referring to tube size (I mislead, sorry)...I'm working on a complete wetsump oil system with a bigger pan where a larger "can" (re-shaped) is beneficial.

As for having a larger tube I can argue that with the larger tube, the pipe flow losses are reduced, thus reducing the pumping losses on the oilpump and ultimately crank thus yielding a power gain

or something like that
