ok, it turns out that it WAS INDEED lifter noise. we took it to one of the import car garage specialists in town and asked their advice. these guys work on Porsches, Bentleys, Jaguars, and lots of classics so i know they'd at least have good advice.
they sold us a bottle of this stuff called "Mac's Valve Tune" from a NAPA for about $3.00 for the bottle. i thought "damn, i've already tried everything, but i'll give it a shot". they said it would take a little while, but it should do it. they indicated that of all the products on the market, this was the one they'd used for years and it was the best.
i went back out to my car and added it to the oil. wouldn't you know it, but about a half hour later, while idling at an intersection, the engine went from sounding like a hundred-piece military marching band... to relative silence!!!!
we were AMAZED! i tried every freaking thing for the past week and THAT is what did it. the bottle is blue, you can get it at any NAPA and it says "Mac's Valve Tune" on it. i don't know what the difference is between that stuff and others, but this worked! give it a shot!

i will, any change and i'll just append it to this post
. in the past, the sludge-remover fixes have lasted around a 15,000-20,000 miles at a time.

I'm assuming you added this after a fresh change of oil? I'm interested in updates after your next oil change too, keep us posted. http://****************.com/smile/emthup.gif

correct! we changed the oil (but not filter)... it seemed almot to be temperature sensitive for a while... cold = tapping slightly still... and this latest bit of hot weather has quieted them down to "like new" quietness. i'm going to change the oil and filter in about another week or so, and do the "ATF trick".
but so far so good. this is nice because it was really driving us nuts!

Automatic Tranny Fluid, soke the lifter in it and then replace it.

Re: noisy lifter clicking noise... SOLVED (B3sat16v)

Ive changed oil minus one quart then add one quart of ATF then run the motor up to temp then go "beat" on it for about 10 miles and then change the oil. You'll be surprised on what you get out of the motor. Usually fixes most lifter noises. Remember using a thicker oil will also quiet the lifters.

What GTibunny16v said.
Almost all ATFs have excellent detergent packages. Longest I've left an ATF/fresh oil mix in the crank case is about 100 miles (of highway driving).
Works good. Thanks for the tip Obin; I've never seen/heard of Macs Valve Tune. http://****************.com/smile/emthup.gif

Re: noisy lifter clicking noise... SOLVED (Electron Man)

Actually - there is no real harm in leaving some ATF in the oil if your lifter noise is real bad - I've had 8V'S in the past that I put like 1/3 of a quart of ATF in the oil and just left it in there - with no problems - and a lot less lifter noise......the detergent qualitiies of ATF make it great to clean out the cylinder head......but I too might try Mac's tune on my next oil change on my 16V - i have found that AMSOIL'S engine flush works very well too - but only about 10,000 miles max before my lifter noise came back.....so....anything is worth trying once....
