It has a small tick at idle. I can live with that, but when I drive at higher speeds, 60-65 mph with 3:50 gear, for about five minutes or so it will develope an extremely loud tick. It as awful. I have to slow way down or pull over for a bit so it will go away. I can do high speeds for a short distance, no problem. But extended high speeds/rpm's will result in the loud tick. So I have to go 50-55 to avoid the issue, and that isn't always good with traffic.
