Hi I was wondering if anyone can help me. I am having a odd rattling sound coming from the passenger side at 1500-2500 RPM. After that I cannot hear it due to engine noise. It happens only when its warmed up and seems to be near the upper half of the engine. The dealer didn't do anything other than open a case with Toyota and MAY get back to me. The first time I took it they told me it was the fuel pump but I told them I know it's not because its been replaced already and it's on the opposite side. Second time they opened the case after letting them actually hear the sound since they thought it was all normal sounds. My engine has approximately 40K and have been hearing this for 3K miles. Video link below, sorry for the vertical video. Sound can be heard at the 2 second mark.

I just got a call and the SA said they found a bad crank rod bearing? Ill get a better explanation later today. I think someone else on this forum had the same issue but my rattle sounded different from theirs.
Going to pick up the rental.
Edit:
I had a recent oil change(less than 500 miles ago) from the dealer and still can be heard.
Update:Update: 1/20/16 After I got it back in mid December I had it for two weeks before a even louder rattle appeared. I took it in the week after Christmas and it was diagnosed with a damaged crankshaft bearing.
Dealer said there was debris in the oil pick up and that they would order all new crankshaft bearings and that it might be ready end of the week last week.
Not sure what happened between that time but I was told yesterday I will be getting a new shortblock
Hopefully I will be getting my 86 back soon.
