Knocking Valver!

[Lucas]

When going along in first gear Ive started to notice that if I release my foot from the accelerator quickly (causing the car to jerk due to the engine braking) that I get a single knock as the car jerks. The noise has come on gradually and is getting more noticable. It also knocks slightly sometimes when I move off in reverse. I havent noticed the knock under any other driving conditions yet (i.e braking or cornering) and the car seems to be driving well in every respect. Any ideas as to what this could be, and what it would take to sort out?

Could be a balljoint or an engine mount on its way out?

I have just fixed this problem in mine - EXACTLY the same thing - This is going to sound silly but - if you have the standard alloy wheels on and the wheel cover is not fitted properly then the wheel will seem to knock- also - the chances are that at least one of the mounts is a little loose - i took mine to a garage and the guy swapped my front aluminium alloy wheel trim covers to the back and put the plastics on the front. One knocking problem solved. Then he tightened the front right mount and the dog bone and the knocking stopped - its not a major problem mate and nothing to worry about so long as you get it sorted quickly.

I do have the standard alloys so Ill try removing the covers and see what that does. Theres also a garage 100m up the road so hopefully if I ask nicely they might tighten up those mounts for me for nothing!

Sorted now - it was the gearbox mount that had come very slightly loose. Cheers
