I have only had my Z for a week and have only ran one tank of gas in it I can hear a knock in the back of the engine. Is this normal. I have not been hard on it AT ALL. It is not that loud but its there.
Yes I am running good gas. It's not spark knock. I have ran high comp. on race engines before. This knock is at the back of the gear box at idle. My crapter I mean rapter also had a little noise in the bottom end.
I was waiting for some of our group to catch up and I was listening for the knock some of you guys hear and it def. sounds like it is in the gearbox. If you put your Z in gear and let it idle then put it in neutral and let the clutch out you will hear a knock.
I get a knock at idle in gear,but i think it's gear lash.I changed my oil after
the first hour and had a bit of metal on the drainplug.I changed it at 5hrs
and had less metal and noise,getting ready to change it again and see.
