  • Early Raceline Duratec wetsump vs. Late.

    One of our fearless members had a problem with oil starvation at a track day earlier this year. (2.3L Ranger engine). The result was a spun bearing.

    He's replacing the engine with a 2.3L Focus motor.

    The Focus motor comes with a balance shaft setup which is easily removed with parts from Cosworth.

    It turns out the oil pumps are different too, causing some interference with the the earlier version of the sump. The early sump was apparenly made by Titan but sold by Raceline.

    Installing a Ranger oil pump into the Focus engine seems to work fine, it measured the same and fits. Testing will tell.

    We also heard rumors that Raceline changed the sump design slightly.

    I called Raceline and they confirmed the changes, also that an upgrade is fairly easy but you may need a new baffle tray and crankscraper. Possibly a dipstick upgrade too. Some minor machining of the old sump may be required.

    The photos below show the early and late sump for the 2.3L I don't know the details of the 2.0L.

    Raceline say this early sump was one of the first 10 made.

    You can see the added baffles in the late sump. We'll make some sheet metal baffles for the older sump.

    Other differences are - the oil pickup point is deeper in the newer sumps and a threaded connector for the dipstick. If your dipstick is leaking it can be retrofitted.

    We don't know if the oil starvation problem was because of the early sump design or just low on oil. Perhaps the leaking dipstick???

    There are differences between Raceline sumps depending on which engine it is for. 2.0L & 2.3L Focus and 2.3L Ranger.

    If you are building a Duratec with the Raceline wetsump - call them first to be sure you get the right one.

    Thanks Doug. It looks like the fitting for the dipstick is different for sure. Scott's doesn't appear to be cast-in to one side like the later sumps.

    As the engine is modular and varies only in height, I wonder why the difference between the 2.0 & the 2.3?

      At least for the 2.3L Ranger and Focus the difference is the oil pump, I don't know for sure what the 2.0L differences are.

      Maybe none, just suggesting anybody check with the experts before they buy.

      Here's another photo, the dipstick entry point doesn't look that different.

      The newer ones have an 1/8 NPT threaded fitting for the dipstick but which came first? I think it was the baffles but this is inference from the converstation as the leaking issue showed up over time.

      The 2.0L Focus and the 2.3L Ranger don't have the balance shaft issue. Only the 2.3L Focus. Probably the Mazda version too.

      My 2003 Ford engine manual does not show drawings or mention the balance shaft in the 2003 Focus
      2.3L.

      I don't know when they added the balance shaft or if the manual is incomplete. It sometimes leaves major details out??

        I have an early 2.0L sump. As you can see from the photo, the crank scraper is not really a scraper, but more of a baffle. Also, rather than bolting to the sump, it attaches directly to the main cap girdle. There are two sheet metal baffles that bolt to the underside of the top plate that mimic the extra cast baffles in the new sump. I need to remove my sump this weekend to repair a bad leak, so will try to take some better pictures.

          Thanks John, the sheet metal baffles added to the plate was what I was thinking.

          The photos will be appreciated.

            Looks Like I have an early one too.

            Here is a pic of mine: http://pierats.com/gallery/sevenbuild/res14422?full=1

            FWIW, I'm running a 2.0L.

              And here is Simon Bell's which features yet another variation on the crank scraper/baffle. Just how many design iterations has Raceline gone through?

                Doug,

                I wasn't able to take any pictures when the sump was off, but I reached down underneath the top cover to get a better feel for the sheet metal baffles. They run from cast baffle to cast baffle and feature a square cutout (~7/16") at each bottom corner to allow oil flow. If you look at the photo I posted earlier, then you can see the 4 bolts that attach the baffles to the top cover. Let me know if you have any questions.

                  Thanks, that is similar to what the extra cast baffles look like as well. They have a hole at each corner to allow oil to flow in.

                  We'll work it out.
