rigs 0 Posted September 26, 2007 Report Share Posted September 26, 2007 Has the car been off the road for a while?How heavy sounding is the tapping noise? Is it a tapping or a knocking?If it hasn't been driven for a while and its a noisy but 'light' sounding tap then it might just be an empty tappet - it should stop once the oil warms.

scampi 0 Posted September 26, 2007 Report Share Posted September 26, 2007 ^^^ WHSIf the car has been stood for a while it is more than likely this. Link to post Share on other sites
xyber 1 Posted September 26, 2007 Report Share Posted September 26, 2007 New oil and filters and itll probably stop, theyre noisey engines anyway, especially when coldIf the oil is black filth, id do a change, run it for 2 weeks or so to flush thru, then do another oil change Link to post Share on other sites
shav nav 0 Posted September 26, 2007 Author Report Share Posted September 26, 2007 cheers guys! do u think its worth takin the cams out to do? the car has been off the road for 3 years but this is the reason why the previous owner put it off the road! is sounds like a loose tapping but i goes away just over 1000rpm and comes back again? goin to give it a good service and see how it goes!! cheers Link to post Share on other sites
Buzzark 0 Posted October 9, 2007 Report Share Posted October 9, 2007 Is it a tapping or a rattling?Could be the timing chains rattling on the guide rail. Mine and a number of others do this with various causes... Link to post Share on other sites
gkjnr 0 Posted October 10, 2007 Report Share Posted October 10, 2007 mine does the very same goes away above 2500 rpm and gets slightly quieter when warm , its quiet annoying such a nice engine can be so noisy and mine just had a rebuild 3000 miles ago too Link to post Share on other sites
dwa1974 0 Posted October 10, 2007 Report Share Posted October 10, 2007 Am i correct in saying that if it was the chains and guides that the noise would get louder with the engine? Sounds like the hydraulic tappets to me, esp if it's be stood for ages. service it and take it for a run Link to post Share on other sites
Buzzark 0 Posted October 10, 2007 Report Share Posted October 10, 2007 Am i correct in saying that if it was the chains and guides that the noise would get louder with the engine? No I don't think so. They seem to rattle at about 1200rpm as that's probably between what the spring can easily hold and before the hydraulic bolt pressure is taking up the tension.At idle mine's completely silent chain wise and the same from approx 1600rpm up.Could just as easily be tappets though as mentioned.Try flushing/diesel oil cleaning/switching to synthetic whichever takes your fancy to remove any deposits likely to be affecting oil flow. Ordered in terms of strength of cleaning (detergent levels). Link to post Share on other sites
