Stu Seen, And My Car Is A Knocking

[whisperuk]

Was that you this evening Stu at about 7.30ish gave ya the thumbs up outta the window Sainsbury's roundabout

Also prob more for big D, I have developed a little knocking noise under the bonnet.

Now if i drive normal oxford roads to work or to town etc it never does it but when i have taken the car out a bit and given it a blast upon the idle it makes a tapping noise from engine area.

I have had it running on normal fuel as I got caught short before so could it be pinking? if that still exists.

I have filled up tonight with 99 octane and it still is doing it tho the fuel wouldnt have run in properly...

Andy ideas would be great.

Oh and there is no hesitation or effect on cars pulling power

Oh Andy you are having no luck at all with this car mate, I will have to hear the knock to have any idea of what it could be sorry, if you rev the car lightly from the throttle body (where the throttle cable goes to) does the knock go away? also if you give the engine a rev then rev it again as the revs are dropping of (if that makes sence to you) does it knock at the point you catch it as the revs are dropping off?

I am hopiing its just piston slap, fingers crossed.

Light tapping still when using cable but when i rev it again after dropping revs its not so noticable. Its only a light tapping noise not a harsh knocking or anything.

Its seems to be coming more from the front, where the altinator belt and the mm wheel/cog thing is but as usual its not easy to pinpoint the noise.

Its ok stu i thought u may have been on a mission to get home that night guess you was on overtime
