I used to have a pinging problem in my GS430, and I couldn't find what was causing it. I took it to a diagnostics shop, and they said my ECU got corrupted, and they reprogrammed it. Cost me $500, but the problem came back a month or two later. It turned out that K&N filter was the cause. The oil from the filter got onto the MAF, and MAF wasn't sending the correct info to the ECU. I replaced the filter with OEM, cleaned the MAF, and the problem is gone for good.

I had a ping/ticking noise on my GS430. DROVE ME NUTS. Of course the dealer "could not hear it". I had a fellow CL member come drive my car and we didn't get more than a quarter mile away and he says "YOU NEED TO GET THIS FIXED!".
Left it at the dealer for a month. Ended up being the fuel return lines vibrating against the firewall on the car. They insulated them and all was better - for a while.
Anyway, I know it is a long shot, but I just wanted to make sure you have them check into other things like this.
