Slight knocking - next thing to try?

[dswarwick]

So this weekend I poly bushed my dogbone mount and removed, examined and refitted by top engine mount. It seems to have improved the feel, particularly the gear change.

Annoying thing is, it hasn't removed the slight knock I get when releasing the accelerator when pulling away in 1st & 2nd.

It's not a loud knock, sounds a bit like the exchaust tapping against something (heatshield?) doesn't sound like a 'bad' knock, but it's annoying when sitting in slow moving traffic (which is when it's most obvious).

Suspension top mounts seem an unlikely candidate?
Could the other gearbox mounts be a suspect?

Is it possible for bits of heat shield to come loose?

Could it be anything around the wishbones or ARB? (turning doesn't affect it).

Or... will I just have to learn to live with it?

i sometimes have the same problem, the heat sheild does come loose on certain sides its just the case of fixing that one or buying a new one, its around £15

 

[dswarwick]

What's the best angle to get at the heat shield around the manifold? I don't seem to have long enough arms!

if you didn't, try pulling the engine forwards before retightening the mounts

 

[dswarwick]

Yeah, did that. Moved it forward quite a lot actually so I was really hopeful that it take care of the problem, but it didn't...

have you had a look at the upper gearbox mount? it's mounted on a spindle that's bolted top and bottom and the bottom nut tends to work loose
