Oil pan return solutions...looking for inputs....
Hey HMT Gang,
Now that the T25 oil return flanges are in production (look for them soon!), we are getting ready to develop an oil return flange. We want to make a flange that will work on the majority of Honda pans. Can you guys reply with pictures and suggestions of what you think the ideal oil return solution is? We want to see what you have done, what worked and what didn't. We are looking for placement, style, and attachment methods. We will not be doing a welded solution, as a lot of HMT folks don't have access to a welder. We want to stick a solution that can be implemented with hand tools. Thanks from Craig @ Tuner Toys |
Re:Oil pan return solutions...looking for inputs....
Hand tools plus a drill and jb weld (optional).
That's what Craig meant (right?) but since we're on HMT he just didn't bother putting it in. I've got no real innovative solutions right now, but if I figure stuff out, I'll forward it to you. |
Re:Oil pan return solutions...looking for inputs....
'card' of Kwik Weld (JB Weld just in 4minutes :P) and a heater hose fitting (think it was 1/2inch) from the Schucks "HELP!" section. then i drilled a hole in my pan with a stepped drill bit (or "Uni-bit") till the hole was big enough. cost less than 10bucks...thats how i did it anyway...

Re:Oil pan return solutions...looking for inputs....
some people use a basic flange w/ a neck on it. how about a flange but instead of a straight or angled neck tube you have a threaded hole and include a few angled necks that are threaded with a kit?
(royalties?? ) lol |

this would work awesome. then just thread in a barbed 1/2 npt nipple and ride. very easy and guarenteed to work |
Re:Oil pan return solutions...looking for inputs....
I would Definatly be buying that flange ASAP....Ive got Stealth mode's Oil return kit, but have nothing to connect the pan hose to except a barb, would really like to see that threaded connection you promise....

Re:Oil pan return solutions...looking for inputs....
Just for the honda's eh? No sunfire (jbody) love :'(
|
Re:Oil pan return solutions...looking for inputs....
i doubt anything they make will only work on hondas...an oil pan is an oil pan for the most part, as far as a return is concerned
|
Re:Oil pan return solutions...looking for inputs....
i would make a flange like the one showed on ebay, but with a neck on both sides.
one threaded neck and one not threaded. The non threaded one goes in the oil pan to minimize oil leak for the ones that drilled a hole that might be too big. |
Re:Oil pan return solutions...looking for inputs....
Excellent ideas all!
The step bit amd JB weld seem to be the most economical and quick solution, probably the cheapest too! We do have one planned similar to the one on eBay, although it will be a better looking design, I hope! On the cast aluminum oil pans, a flange design will work fine. In fact we already have a prototype in the works, it has a male AN fitting as an integral part, which is made to work with the Stealthmode style of return line. Check the picture... However, on the stamped oil pans, the flange will need to be backed up on the oil side, with another flange, to give the gasket good support for sealing. This brings another question....What is the best mounting location for the oil return, on a stamped oil pan? Props... - Semnos, nice idea on the internal neck, that would really reduce the opportunity for seepage of accumulated oil where everything mates up. - CRX88Si, if we end up with a threaded female flange, the straight, 45, and 90 included necks sounds great! - Not to leave out the JB Weld crew, way to get it done! |
Re:Oil pan return solutions...looking for inputs....
BTW - The flanges pictured above will be ready in the next few days, at least for cast pans.

Re:Oil pan return solutions...looking for inputs....
how much are we looking at spending on these new fittings? i'm stoked on this.
|
Re:Oil pan return solutions...looking for inputs....
We are not sure yet, but we want to keep it well under $15. It will be cheaper for those with cast pans, as no inside backing flange is needed. Those who will be installing these in stamped pans will have an additional piece on the inside of the pan to make a stiffer final install. Kinda making a sandwhich of the stamped material between the two pieces.
We are also sourcing aircraft hardware for these, as I want our customers to be able to safety wire them in place to further reduce the chance that something will come loose and end up in the mechanicals. The kits will include the flanges, the gasket, the hardware, we may even throw in a bit of safety wire. Craig |

Re:Oil pan return solutions...looking for inputs....
i used a -10 an fuel cell fitting and a lot of sealeant no pics though i will get one of the summitsite and edit tomarrow

Re:Oil pan return solutions...looking for inputs....
On the placement, the best idea I've heard is as high as possible and in between crank throws to avoid the rods interupting the oil (gravity) flow.

Re:Oil pan return solutions...looking for inputs....
Similiar to Semnos' idea.
Have one flange threaded and the other slip on. People will put the flange they need on the outside. http://www.desktopimports.com/hmt/oil.jpg |
Re:Oil pan return solutions...looking for inputs....
you really don't need a gasket on the inside of the oil pan. Depending on where you mount the return you can actually loose horsepower, no ----.

Re:Oil pan return solutions...looking for inputs....
Shadow - Just picked up the same fuel cell type fitting from Barry Grant. It has the nice radius on the inside and AN 8 on the outside (the T25s are much smaller on the drain side.). There is just no way to ensure the nut does not back off...
Stealthmode - I'm with you on that, it will have to be quite high as well, since the internal baffle gets in the way of anytrhing lower. WhiteRice - Excellent illustration of a great idea. We'll probably do three pieces, the slip, the threaded, and a single backing plate that works for both styles. This will be cheaper for all in the long run. |
Re:Oil pan return solutions...looking for inputs....
using that illustration as a reference, why not have the bolt on the insided coming out and a nut on it there. then if you can find a bolt that has a hole in it you can use some cotter pins to hold it in place. With the nut on the outside inspection is easier aswell.

Also add a washer+lock washer and that'd be a mint idea. When do they start production, I want one! :)

Re:Oil pan return solutions...looking for inputs....
Excellent idea Stan.
We'll probably build a backing plate as well, and then just send whichever fitting the customer wants, I think it will be a litle cheaper that way, as the backing flange can be waterjet cut. Craig |
Re:Oil pan return solutions...looking for inputs....
http://www.desktopimports.com/hmt/oil.jpg It might be wiser to use the nuts outside the oilpan, since you couldnt use nylon lock nuts, as over time oil might swell the nylon. And outside you could use threadlock compound. |
Re:Oil pan return solutions...looking for inputs....
I agree about not using the Nylocs. We are looking at the available aircraft hardware from a local supplier, as I'd really like to be able to safety wire the whole thing. I'd hate for something to come loose and be able to fall back into the pan. It would be nice that any hardware that might loosen be retained by safety wire.
Craig |
Re:Oil pan return solutions...looking for inputs....
on the backing off. Yea I put some seals all on there :) that way when it was tight it was froze in place. I like the 2 bolt flange idea maybe with nylon lock nuts? also think about a little cover so there is no windage pushing the oil and holding it in the drain.
