when i lift off the throttle i can hear either the tapttes or cams

is this normal on throttle is sounds amazing and pulls strongly but when i lift of i hear what sounds like tapptets goin nuts "cause of the revs"

does it at any revs and any speed.

i think its normal but going from 8v's to 16v's i need some reasurance

Only noise mine makes on throttle-off is if I slam the throttle shut so quickly I get a noise out my induction kit...

my c20xe rattles when i come off the throttle at high revs.
my civic did this also. on the civic it was a loose catalyser heat sheild. easy fix.

not sure about the xe though. haven't investigated fully yet.

i think as they get older they tap a bit more, my old one (90oddK) used to do it a bit when it was at high revs...

my new one (1.6 16v with 42K) on it is as quite as you like

You got a exhaust system fitted? is it the engine you hear or just general noise? When I lift off I get a lot of pops and burbles from exhaust (I mean loads - too much perhaps?)

I gets loads of that off my 1.2 16v exhaust too. And I think it taps quite a lot for 46k aswell

yeh taps a lot on my 50,435 mile engine... think it might just be injector chatter - or whatever...

I said to my dad the other day about how slow my car is these days... he replied 'To be fair, you do push it quite hard' ...

My dad says the same We both think the tapping makes it sound like it's steam driven when it's off throttle

I can't really hear the tapping inside the car, only when I open the bonnet and look at it - my mate has a 1.2 16v GLS same as yours and his taps louder than mine

I think the cam chain also adds to the noise a bit in X12XE's... at the moment as I pass about 4.5k rpm I get a high pitch noise rather than exhaust noise - as it leans out
