stobbie Posted June 6, 2009 Share Posted June 6, 2009 Hi, I have a problem with my 300TDI... A few weeks ago I lost servo assistance on my brakes. So I bought a new Wabco vacuumpump from Paddocks. No servo is back, but..... A few days later my TDI started to develop a ticking noise starting at around 2000~2500 RPM. It does sound a bit like a vacuum pump tick, but how big are the chances that a new one breaks within two days??? Quote Link to comment Share on other sites More sharing options...
DrRob Posted June 6, 2009 Share Posted June 6, 2009 Have you used the search faciility on here? I remember the same question a number of times. I developed a tick on an ex-300tdi of mine. Turned out to be a valve stem collet or whatever their called. Cost a few pence and a 10min job. Take the rocker cover off and check to see if their all in place.....

Rich_P Posted June 6, 2009 Share Posted June 6, 2009 Could it also just be poorly set tappets? Quote Link to comment Share on other sites More sharing options...
stobbie Posted June 6, 2009 Author Share Posted June 6, 2009 I don't think so. It wasn't there one moment, and the other moment it started. I think poorly adjusted tappets would have developped the noise gradually. Quote Link to comment Share on other sites More sharing options...
