CageyH Posted December 10, 2006 Share Posted December 10, 2006 First check under bonnet for a chicken. If no chicken, then see dry sump thread... Only dead fish go with the flow.... Link to comment Share on other sites More sharing options...
Pelico Posted December 10, 2006 Share Posted December 10, 2006 Could it be detonating ? Does it improve when the engine warms up ? What ECU / map are you using. Most likely to be you oil seals sucking themselves inside out - see the dry sump straw poll. Link to comment Share on other sites More sharing options...
Myles Posted December 10, 2006 Share Posted December 10, 2006 Could be a crafty mouse, trying to disguise itself... Scene: A garage, somewhere, sometime... Cluck, cluck, cluck... "Hmm. No chickens here..." "...not even underneath this mouse..." "How strange..." Cluck, cluck, , cluck... I'd search out the dry-sump threads... 🙆🏻 🙆🏻 🙆🏻 🙆🏻 🙆🏻 Alcester Racing 7s Equipe™ 🙆🏻 🙆🏻 🙆🏻 🙆🏻 🙆🏻 Alcester-Racing-Sevens.com Edited by - Myles on 10 Dec 2006 13:35:30 Link to comment Share on other sites More sharing options...
Delbert Posted December 10, 2006 Share Posted December 10, 2006 Myles, Step away from that Spliff now 😬 😬 When I get the mean reds the only thing to do is jump in the 7 ( with applebogies to Audrey) Link to comment Share on other sites More sharing options...
rj Posted December 10, 2006 Share Posted December 10, 2006 If it disappears as the engine warms up I'd guess it's piston-slack. Sort of TADS. /r Link to comment Share on other sites More sharing options...

Peter Carmichael Posted December 10, 2006 Share Posted December 10, 2006 Aural confirmation that a volumetric scavenge pump is unable to suck nothing. It is a quirk of the dry sumped cars' breathing arrangements. On a standard R400 it seems to work out OK. R500s use the same arrangement and they work out OK (generally). I prefer alternative arrangements that work OK. Choose your poison. Edited by - Peter Carmichael on 10 Dec 2006 19:05:22 Link to comment Share on other sites More sharing options...
Jason Plato Posted December 10, 2006 Share Posted December 10, 2006 It the auto HGF warning unit When the HG fails it stops clucking 😬 ( I can say these things now that I'm on the Ford bandwagon ......... heavy 🤔......nah 😬} here is C7 TOP Taffia Area Rep Link to comment Share on other sites More sharing options...
Peter T Posted December 10, 2006 Share Posted December 10, 2006 Anyone for KFC then ???? Serious note though, the clucking is a normal sound of the air/oil being scavenged from the sump by the external oil pump. I use to have the noise, but after modifying my oil breather routing as Peter Carmichael suggested it ceased to make the same noise. So i no longer hear it. *thumbup* Ohh and my oil catch tank is a lot less also. *thumbup* R500 Mango Madness Link to comment Share on other sites More sharing options...

Slipper man Posted December 10, 2006 Share Posted December 10, 2006 Provided you have a dry sump system, it is absolutely normal and nothing to worry about. As Peter C says, all you are hearing is the scavange pump sucking on air, having done its job and sucked all the oil out Link to comment Share on other sites More sharing options...
Peter Carmichael Posted December 10, 2006 Share Posted December 10, 2006 I was saying it was "sucking on not air". Link to comment Share on other sites More sharing options...
Slipper man Posted December 11, 2006 Share Posted December 11, 2006 Alright, Mr Picky - sucking on a vacuum then Still perfectly normal (except that mine doesn't do it any more so perhaps I should worry! Link to comment Share on other sites More sharing options...
Peter Carmichael Posted December 12, 2006 Share Posted December 12, 2006 You did misquote me... However normal it may be, I could find you a roll-call of engineers explaining exactly how it is poor practice. If it works, fine. As mentioned before, I prefer my own (well-documented) poison.

DohNut Posted December 12, 2006 Share Posted December 12, 2006 "I prefer my own (well-documented) poison." I know it must be depressing repeating yourself - but things aren't that bad N Link to comment Share on other sites More sharing options...
Gridgway Posted December 12, 2006 Share Posted December 12, 2006 so do you make an engineering practice good by documenting it well? Graham Link to comment Share on other sites More sharing options...
