So how do i ensure that I've got as much of the old oil out of the car as
possible? I have the Moss oil cooler kit installed and all the blue hoses
that supply it have their share of low points.

One thought was to disconnect the fuel injector relay and then crank the
engine for a few seconds, but unless the oil pump rotor seals well enough to
push air through the system via positive displacement i don't know if that
would work. any thoughts?

I'd really rather not disconnect the hoses individually.

You mean you didn't install drain valves at the lowest point on the oil
cooler system?

DO NOT unplug the fuel injector relay and crank the motor. (I know you
*must* be kidding on that one, but I had to say it anyway.) 1. The oil
pump doesn't seal well enough. 2. A motor w/o oil, even cranking just
the starter would not be kind to you various bearings.

Truth be told, there isn't really all that much oil left in the system
after you drain the pan and remote filter, (or regular filter). Don't
worry about it. If you really can't sleep, then install a petcock on
the lowest blue hose. Just make sure it is a very good quality one and
that it doesn't restrict flow.

The percentage of dirty oil left in the system is small and the fresh
oil will dilute it considerably. Then the clean filter will be able to
catch those dirt particles as they are flushed through the system by all
that nice clean oil.

Why worry, be happy. :)

Even though it could be considered overkill - I do two oil changes ( an hour to
a day apart ) ... to further dilute.

Of course, I have not practiced this on the new engine yet and it is a bit
burdensome - I also feel comfortable not using synthetics if you change every
3500 miles.

FWIW - Dan
