    Deep oil pans for '70's airheads?

    Years ago (circa 1985) there was a rage about Deep oil pans for '70's airheads. I own a '78 R100/7, and am wondering if they still are available.

    Jimmy -

    Yes, it appears some are still made. Anton has info at the bottom of this page:

    Note his caution about centerstands and clearance.

    Personally, I'm fine with the stock pan on my /7. I did put a slightly deeper pan on my R25/2. It only held a little over 1 quart...yikes! I thought maybe another 0.5 quart of oil might be the way to go.

    I have a deep oil pan on my 78 R100S. To make this modification completely effective , you need to lower the pick-up of the pump also.

    I had one on my R100S that I sold last fall, but have the standard pan on my R100RS.

    Honestly, I don't know, I certainly don't think it's one of those mods that you HAVE to do.

    I put a later mdl pan and pick-up on my '78rs only for the following reason, and I quote Largiader,

    "The deep pan and cast pickup are better than the earlier designs, so you can get more reliable oil delivery using the newest parts. Additionally, the greater air volume in the sump means less fluctuation in crankcase pressure and therefore less oil lost through the breather."

    My bike was blowing a lot of oil through the breather into the air filter area; the larger pan with the baffle seemed to help. I still use same amount of oil and dip stick as I did with the old pan. I just took notice where it came up to on the dip stick when I first changed it and added full oil change.

    You can find them on ebay or IBMWR Marketplace; just make sure it's '81 or newer and comes with the adapter and pickup parts.

    "I put a later mdl pan and pick-up on my '78rs only for the following reason,"

    What does "mdl" stand for?

    I recently installed a later year ('81+) deeper oil pan with baffle on my 1978 /7. The center stand just clears the newer model oil pan. Here are the BMW part numbers I used:

    07119919143 screw plug
    07119963300 gasket ring
    11131336995 oil pan (1981+)
    11131338427 gasket (oil pan)
    07119902993 hex bolts
    07119932099 wave washers
    11411252226 wire-strap
    11411337509 perforated plate
    11411337536 intake manifold (oil pickup)
    11411256258 gasket

    Many of those parts, like the screen and the 14 bolts, are the same between different oil pan versions. You need the pan, a fresh gasket, the matching pickup and its bolts, and maybe a new dipstick. And a new crush washer but that should be obvious.

    How much oil volume did this add? 1 Qt? Less than 1 Qt? Also, did these parts also lower your oil pick up suction screen down an equal amount as the new depth of the pan?

    What I am wanting is a "buffer" just to make sure that I NEVER go low on oil, and the added benefit of cooler oil.
