now that it's finally cooling off in the deep south, I've been driving with the windows down and the air off a good bit, and I've noticed something
when I shift up while running moderate acceleation - the valves rasp just a little as the clutch comes out the last bit and the engine and drivetrain sync up. It does this if I'm revved a little higher and the drivetrain slows the engine slightly as it locks up - which is fairly often since it tends to hold the revs up a little as you shift. I don't hear it all the time under the same conditions, either. If I'm slow and careful in shifting, it's fine, and if I speed-shift it, it's fine.
I know some of the new comp-run engines are set up so that a little valve rattle under certain conditions is normal (Chevy trucks for example), but it grates on my nerves a little. Anyone else hearing this?????
