M20 Oil Pan Baffle Extension Plate DOWNLOAD FILE

Postby LEAN_E30 » Thu Oct 10, 2013 5:32 am

-yuush- = this is an awesome smiley.

We m20 drivers with a sorted suspension have all seen the oil light and pressure drop under hard corning situations. This is my Cheap and Free solution that I share with you all. I have submitted it into the public domain/commons of the interwebz, if you don't like it you can go fuck off, if you dig it and want it, have at, may this file and m20 powered e30s live forever.

In late January 2012 I produced an oil pan baffle extension plate design and installed it, I had a spare cracked pan sitting on the shelf, a big hammer to convert that crack into a hole, and a few spare parts (like pumps) laying around and mocked up a design on poster paper onto some card board & scribed/scan/repeat until i was satisfied. I then sent the vector file over to a local sign shop who has a router table and had them cut it out of .080 aluminum plate (.080" & .063" aluminum are common sign substrates. I would not use the .063", the .080" seems like a perfect rigid thickness) I then rivited the final part onto my current pan's factory baffle. I made a tight fitting design and it cost me $20 and 30 min, plus a gallon of gas to go pick it up. I had two plates cut (~$10 a piece) thinking I might experiment with one or have to file it back during install, but it came out great, so i have a spare... for that m20b23/731head sitting on a shelf next to my kegerator that eye-balls me every day when i come home from work, begging for parts and attention :mrgreen:

I haven't gotten a chance to really test it (on a track) however, hoping to get out there, but life just keeps happening. It seemed like an economical solution to the oil idiot light problem I was having on aggressive sweepers. I think this should do the trick for the degree of action my e30 sees, or might see during the future it'll have under my watch. High Plains Raceway will probably be it's first real track experience if i can keep my project priorities straight and resist spending money on the e34... outside of maybe a couple hopeful track days or autox's, my e30 serves mostly for my sole enjoyment off by myself without competition or stop watches, back mountain roads and summit passes.

I sized the holes for a 3/16" drill bit/pop-rivit. Three aluminum rivits and it's not going anywhere. So far i've put a couple thousand of DD miles on the car between intermittent garage hibernation stints, the baffle seems to do the trick for me. A windage tray would be cool, but i doubt i'd leverage that at all.

FYI, it's a PITA to install one of these on a motor that is in a chassis on a front subframe. it's quite doable, but you know how you only have like 1-1.5" of normal clearance when you drop the pan in order to drop the pump into the pan? - well how this fits nicely around the pump, also cuts that normal-condition work space clearance in half. just a heads up.

...the PDF file is 100% scale, so anyone can contact a sign shop or machinist with a router table and have their own cut out of .080" aluminum plate. A part like this should not cost more than $10-$15ea, tops. It would be a rip-off and an insult if it cost more than that. It's just a rediculously easy part to fabriacate and I think everyone should have one. Worst case you can print out the PDF file @ !100%! scale and use the print as a stencil and hand-cut a baffle extension plate out. Do this at your own risk, yada yada, if you have a problem with this or me you can go fuck yourself, other legal jargon, etc, etc... Email me for a .AI or .DWG file if you can't seem to make the PDF work for you and i'll forward an email with it to you for free. I can be reached through PM here or on the 'Tech. Happy motoring.

Edit: just uploaded the pdf here, images also link to the PDF, hope it works and all of you love it: https://upload.wikimedia.org/wikipedia/commons/3/36/BMW_M20_OIL_PAN_BAFFLE_EXTENSION_PLATE.pdf

I thought I remember M20 oil pans already having some baffling. It's been so long.

also, lol at the demo pan having a big gaping hole in it.

-Emailed.
-Enjoy!
(it's just a 2d polyline, not an extruded solid or anything like that, but should be clean enough to jump right on it without much excess effort.)
