Danza V Posted July 12, 2013 Share Posted July 12, 2013 Hi all, my daily rubber has the a rattle for a few secs on start up then disappears straight away, even when cold. I think it's valve clearances, but the query j have is whether they can be adjusted on this engine or they self adjusting? It's literally for 2 secs starting from cold and even when it's still cold and warming up it doesn't do it.. Is this a big issue or not really? I'm not sure whether its just that time before the oil reaches that part if the engine? by the way it's a 2001 vw polo gti I know this is a TOYOTA forum but you were all so helpful with my V I can leave Quote Link to post Share on other sites
StuDoc 72 Posted July 12, 2013 Share Posted July 12, 2013 Its not the tappets. Its because the top end is dry when you start then soon as the pump gets oil up there it stops thats why it only lasts 2 secs after start up. Quote Link to post Share on other sites
Danza V Posted July 12, 2013 Author Share Posted July 12, 2013 That's exactly what j thought studio, but I thought I'd go on the polo forum and check and they were all saying " tappets etc. I mean j was abit stumped because if it was tappets it would doing all the time, especially when cold. So If in right it isn't a real bad thing? Just must be a bad design on vw part.. Quote Link to post Share on other sites
StuDoc 72 Posted July 12, 2013 Share Posted July 12, 2013 Id very much doubt a 2001 polo gti has tappets it will have cams and cam followers if they needed shimmed, re ground or replaced id imagine it would do it constantly. Quote Link to post Share on other sites
Danza V Posted July 12, 2013 Author Share Posted July 12, 2013 It only makes a rattle/diesel kind of sound on start up then is fine and runs and idles like a dream. I was %99.9999999 sure they didn't have adjustable clearances. Quote Link to post Share on other sites
