hadders211 Posted April 21, 2014 Share Posted April 21, 2014 Evening guys. Been tearing my hair out over a 'clunking' noise, coming from my engine at idle. Started off pretty quiet, but over the last month or so, it's become progressively louder. It's now gotten to the point that along with the noise, my airbox seems to shake pretty badly at idle, almost asif it's stalling, then it'll pick back up again. Could this be the CAT internals? Or something more serious. Had a quick scower about, but can't find anything obvious. Drives perfectly. I've uploaded a video, to give a better indication of what I'm talking about.

delboy Posted April 22, 2014 Share Posted April 22, 2014 i would do a change of oil...plugs..filters and perhaps the aux belt & have the pullys checked then you can try a bottle of tappet additive just put the whole bottle in with your engine oil and run car as normal.you do not have to change the oil after adding the additive until normal service times.it stopped my rattly engine but you need to be patient as it take quite a few miles to get working mine took about 2 weeks + to be noticable Quote Link to comment Share on other sites More sharing options...
james_60 Posted April 28, 2014 Share Posted April 28, 2014 Hi Idle control valve or leads/coils Jamie Quote Link to comment Share on other sites More sharing options...
delboy Posted April 29, 2014 Share Posted April 29, 2014 may also think about replacing lambda sensor but the idle control valve is easy just 2 bolts to remove & give it a good clean as it get gummed up Quote Link to comment Share on other sites More sharing options...
hadders211 Posted April 29, 2014 Author Share Posted April 29, 2014 Thanks guys, will be sure to check this out. Could anyone tell me where these are located on the new ka? Wouldn't have thought an idle control valve would cause what sounds to be a knocking/clunking sound, such as fhia......

hadders211 Posted May 5, 2014 Author Share Posted May 5, 2014 Hi Guys, After many weeks of looking into it here and there I think I might have found the cause, or at least found a reasonable suspect! The flywheel bolts. A few have listened and guessed this. Going to have a look and I'll report back. Cheers!

hadders211 Posted May 6, 2014 Author Share Posted May 6, 2014 Hopefully so Delboy, not yet had the box out. I'll get round to it soon. Will be my first time removing a box on a car, not the usual wagon! I'll keep it posted. Sent from my iPhone using Ford OC Quote Link to comment Share on other sites More sharing options...

Andy62 Posted June 24, 2019 Share Posted June 24, 2019 Hi Guys Just seen the posts and would like to know where the ISCV is on the mk2 ka 1.2 petrol 2009 RU8 (not the purge valve under the throttle body). I am no mechanic but have been told mine has one but cannot find it. On eBay shows it as round 75mm X 50mm with conection plug ar 90 degrees Many thanks Andy.
