  • Raceline Sump Drain Plug Thread Size?

    For a ZX1 Zetec engine. Anybody happens to know?

    Also, did somebody try the Aeroquip Quick-Drain Couplings?

    Thanks!

    I was told by Raceline that they are a standard British Pipe size.

    The small one looks like a -8 the larger a -12. I measured .825" and 1.040" respectively.

    The parallel thread type.

      Thanks Doug, but that is an odd one. I don't think any of the Aeroquip plugs will fit.

        I think you are correct, unless you are a fanatic and buy an oversize fitting that we can machine the BSP threads on.

        Wait!...... forget I mentioned it.

          They might already make an adpator.

          The stack up might be cumbersome but maybe not.

            Problem solved (tapped to 7/8" 14tpi thread):

              Don't forget the safety wire.

                Not sure if I need that. The cap has a lot of friction with its rubber gasket and the quick coupling drain spigot has a valve built in. Even if I should lose the cap it drains only when the counterpart is inserted (that has a drain hose attached). But maybe I will get a spare cap in case I do lose it.

                  Gert,

                  That is really cool! When you change the oil, is there a hose that you plug into the fitting?

                    I leave about a foot of hose attached to the female fitting (has a hose barb). For an oil change I just twist the dust cap off and plug the fitting in with the hose hanging into the catch pan. No wrestling with the plug, no mess and I don't need to take the sump guard off.

                      I found that with the Raceline wetsump for the Duratec, draining conventionally left close to a liter of old oil in the sump (I confirmed this when dropping the sump to install new rod bolts). I now use one of these which removes virtually all the oil and is very easy to use. I haven’t had the sump plug off for a couple of years.

                        John,

                        I thought it might be leaving oil in the sump, but was not aware it was so much.

                        How do you get the hose into the sump - through the dipstick tube?

                          Tom, yes, it slides right down the drain tube. Towards the end of the drain cycle I move the hose up and down a bit to ensure it is getting all the oil.

                          As background, I pulled my sump a few years ago to fix a leak. After performing a normal drain process (engine up to temperature, car level on jack stands) I was shocked by how much oil was still in the sump. Curious, I poured the excess into an empty container and it measured almost a full quart. After buying the Pela, I removed the sump again (this time to install ARP rod bolts) and confirmed that it had evacuated virtually all the oil.
