Hi,
First of all, i am not sure if this is the right place... but , here goes my issue...
I have 2 cars at the moment. One is a Seat Ibiza with the 1.9Tdi AFN 110hp engine. The turbo is a VNT15/17.
The other is an Audi 80 1.9Tdi 90hp Avant, 1Z engine. The turbo is a GT15.
Well, keeping the turbo issues apart from the discussion... does any one know why the audi engine a lot noisier than the 110hp ?
Neither of them has an engine cover. The Seat 110hp has a "normal" diesel engine noise, and doesn´t produce hesitations/vibrations....
But in the Audi, i can hear easily the " clak clak clak tak tak tak " noise while operating, and produces a lot more vibrations in specific revs (specially the lower ones).
Any ideias on this? I´ve thought on the Injector Pump timing may be too advanced in the Audi , has it´s value in Vag.com is 78 !
But, may the valves ? Or the cam followers or lifters? I heard that damaged lifters may produce this kind of noise.
Any help would be so much appreciated. The Audi is a Fantastic car, but the Engine noise that gets inside the car is not pleasant at all.
I´ve also made a comparison bettween them, with the hood open , and working at the same time.
Even the engine code is the same in both engine (serial number near the 3rd injector).
Injection pumps may be different, but i believe they´re both Bosch VP37 and dont think that it would make that big difference about the noise issue. They´re both direct injection.
Thanks!
