I recently had all my heat shields removed by isuzu. Apparently isuzu has issued a directive stating that this is the cause of the majority of noise complaints, and now doing so by the dealer will not void any warrantees.
So Im sure thats not it. It clearly is coming from the botoom end, right by the oil pan. Its not the injectors. I dont see how it could be anything else down there.

AND JOHNNIE, yes it is for SURE part of my warranty clock ticking. Im down to the last 12000 miles.
