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
