Norrisvr6 0 Posted March 29, 2006 Report Share Posted March 29, 2006 Hi,i posted recently about my 1996 vr6 golf making a weird noise at 4000 rpm and everyone who replied said it was tappets however if it was tappets would it not make the noise all the time this noise only happens at 3900-4000 rpm and its like a loud ticking noise whenever the power band comes in however disppears after 4100 RPM any ideas to what this could be as its really annoying me? Maybe it is tappets if so how do you quieten them?Thanks Richie Link to post Share on other sites

dubloke 4 Posted March 29, 2006 Report Share Posted March 29, 2006 it could be a sticking tappet, remember it has two cams that have a power band around that area. the only way to really quieten them down is to get them replaced! Link to post Share on other sites
Norrisvr6 0 Posted March 29, 2006 Author Report Share Posted March 29, 2006 If it sticking would this cause major damage or will it eventually free itself? How much 2 replace tappets and what else should i replace at same time? Link to post Share on other sites
antera309 3 Posted March 29, 2006 Report Share Posted March 29, 2006 Exhaust leaks can make a ticking sound at certain resonating frequencies. It's worth checking the exhaust system (including the manifold) for leaks before you start taking your engine apart! Link to post Share on other sites
mk2timbo 0 Posted March 31, 2006 Report Share Posted March 31, 2006 hello there, i have a sticky tappet but you can only hear it until its warm then it stops. i dont know much about the lump yet as ive not had it in bits but could it be the timing chain? Link to post Share on other sites
28v6r 0 Posted March 31, 2006 Report Share Posted March 31, 2006 A couple of questions...Does it happen under load i.e in gear?Or can it be replicated stationary?If the second, try putting a long screwdriver to where you think the sound comes from and put your ear to the end of the screwdriver and listen ...Then tell us what you find..

57ORM 0 Posted April 20, 2006 Report Share Posted April 20, 2006 sorry to jump in but what is pinking I heard about this a few times and don't have a clue what it means. Link to post Share on other sites
VR6Pete 1,455 Posted April 20, 2006 Report Share Posted April 20, 2006 sorry to jump in but what is pinking I heard about this a few times and don't have a clue what it means.My understanding of it is that the knock sensors kick in and retards the map. in some cases it can be audable and heard quite clearly. I can only describe the noise as dropping a load of small nails on a metal surface... Pete Link to post Share on other sites
