Bought this Lexus about a year ago. It has always had a engine knock when slowly accelerating between 1000-2500 rpms. If I rev it strongly the noise does not occur. It definitely feels internal and is not a ticking sound, so I ruled out lifters. What do you think?

Possibly a bearing knock due to low oil pressure, i would have the oil pressure tested with a mechanical gauge, post reading cold idle, hot idle and hot 1500 RPM.
