JimC Posted June 12, 2006 Share Posted June 12, 2006 Hi guys, i recently purchased a '98vvti tt. The first thing i have noticed is a rather loud tapping coming from the around the injectors. Initially, thoughts of a duff/ sticky injector were causing the problem, but being that it can be heard whilst driving slowly (before the exhauist noise takes over everything!!!), my gut feeling was that it was too loud to be injectors. I know BMW's are "tappy", but this is pretty loud. Could it be tappets? Any suggestions guys, towards diagnosis and sorting it! Cheers Jim Quote Link to comment Share on other sites More sharing options...
TRD3000GT Posted June 12, 2006 Share Posted June 12, 2006 Im betting its still your injectors. If your nervous have them flow tested and cleaned Quote Link to comment Share on other sites More sharing options...
JimC Posted June 12, 2006 Author Share Posted June 12, 2006 ok thanks...may just do that and see where i'm at. What makes you so confident. Are tappet problems rare in supes? Quote Link to comment Share on other sites More sharing options...
TRD3000GT Posted June 12, 2006 Share Posted June 12, 2006 Ive never personaly heard of anyone having tappet problems in 4 years here even on badly maintained cars Quote Link to comment Share on other sites More sharing options...
JimC Posted June 13, 2006 Author Share Posted June 13, 2006 If it was a sticky injector, wouldnt you expext to hear an uneven tapping noise. As it is it is pretty regualar, and increases its frequency as expexted with increasing rpm. Quote Link to comment Share on other sites More sharing options...
Gaz Walker Posted June 13, 2006 Share Posted June 13, 2006 The injectors are pretty loud on the Supra Jim, I think you'll be alright Quote Link to comment Share on other sites More sharing options...
JimC Posted June 13, 2006 Author Share Posted June 13, 2006 thing is...my dad has a 98 vvti tt identical to mine, and my brother a 96 tt all bpu, and neither of the other two show any signs of noise from the injectors! thats the worrying thing i guess. I am a little worried about pushing the car in case it is running lean in places as a result!!! bad news! Quote Link to comment Share on other sites More sharing options...
