Re: whats the best way to do an oil flush
The only time I would not recommend doing an oil flush is on a car that has been neglected, otherwise if your vehicle has been taken care of an oil flush really won't hurt it. The people that have sludge buildup underneath their valve cover and sitting in the oil pan are the people who don't take care of their cars. I took the valve cover off my girlfriend's D16Y7 with 125k miles on it and there was NO sludge on the underside of the cover.
I posted up a Seafoaming method that has a small oil flush procedure inside of it. If you want, give it a try. If your motor is in poor condition though, I'd not recommend doing it.

Re: whats the best way to do an oil flush
i'm not a fan of seafoam, but i am a fan of engine flushes. here's my procedure:
you will need:
2 cheap oil filters from advance or wherever you go, 1 honda oil filter
8 qts ATF (automatic transmission fluid, use only dextron III w/ mercon)
2 qts valvoline all climate (my favorite conventional because its the clearest. pennzoil is great, but it is very dark which helps stain the inside of the engine. im just real picky...)
x.x qts valvoline all-climate (or even maxlife, if you have some mileage on the engine- its good stuff) to do a final oil change on the car.
1. if you suspect the oil pan has sludge, remove the pan, clean it completely, and reinstall w/ new gasket (and a dab of hondabond on each bolt/stud). if you just purchased a used car, or an old engine, i'd recommend this. only skip this step if you are aware of your pan's contents/condition.
2. if you skipped step 1, then drain the oil. if you did step 1, then you've done step 2.
3. tighten up oil plug.
4. install a new cheap oil filter.
5. pour 4 qts ATF into engine, followed by 1 qt of oil. ATF is basically 0 wt motor oil, but its full of detergent cleaners, which are safe for your engine
it just doesn't last very long in an engine (~300 miles?)
6. crank up the car. i usually drive around for about 10 minutes. drive spirited, playing a little to get all that stuff mixed around good. just don't beat on it real hard, and don't do above 7000 RPM. lightly hit vtec, so all that gets cleaned out, too.
7. back to the shop- let it idle for like 5 mins, then shut it off.
8. remove filter & oil plug. let the oil drain VERY WELL.
9. repeat steps 3-8.
10. at this point, your engine should be very clean on the inside. plug up the oil pan, add however much oil your engine recommends, install a new honda oil filter, and you're golden
this is kind of a double-flush. feel free to skip step 9 and save yourself buying 4 qts atf & 1 qt oil if you feel your engine isn't THAT nasty inside. this can also be done once a year to keep up ye ol internals
