knock on start up from NSF

[123stevevw]

Ive done a search and can only find info on strut top knock but its not the same fault

When ever I start it up there is solid donk donk donk noise from the NSF area, any ideas? common faults?

Thanks

Steve

Is everything tight, engine cover etc?

Have you got a strut brace fitted? Might be an engine-cover bolt catching the brace

everything seems tight, covers ok, no brace, thanks though

any more ideas peeps?

Engine mount on NSF?

hmmm

could it also be the gearbox mount?

Is it definately from the NSF, only knocks and bangs can be hard to pinpoint due to echos etc. are the exhaust rubbers worn, my exhaust used to hit off the tunnel on start up as the rubbers were perished.

actually, saying that ^^^, I do get the same sound on the occasion when driving over uneven surfaces (i.e. shite country roads around here!)

I'll have a look when I get some time this week

definatly sounds like an engine mount, just because it "sounds" like its coming from the nsf doesnt mean it definatly is the sound may be vibarting up through something else..

possible gearbox mount under the battery

not certain if petrols have them, but my dci has a large weight mounted under the engine mount, when i had my cambelt done this worked its way slightly loose. Used to knock over dodgy roads.
