Hi all, I have a strange rattle I cannot diagnose.
I drive a Ke74 Corolla, 5kj engine and T40 box, there is a rattle when decelerating. I can't tell if it is coming from the drivetrain or the engine... it only seems to happen in 3rd or 4th gear, when decelerating and completely off throttle between 4000 - 3000rpm. Adding a little throttle or clutch in ever so slightly and the noise goes away. Could it be a lean condition when off throttle? A bearing in the gearbox?
Cheers for any input, Ol.
