Probably not. I've heard noisy injectors tick away for tens of thousands of miles. If you want to replace them, the injectors are under $60 each from alloembmwparts.com, same as a US E28 533i, E24 633CSi, E28 M5, E24 M6, and probably a few others. Or you can remove them and send them to RC Engineering (www.rceng.com) for cleaning/blueprinting/balancing. Good injectors usually work for a VERY long time.
Valve adjustment is ok i just did that not too
long ago. I have use my wife stethoscope and I'm
positive Noise is comming from the injector.. it is more pronounce if i place stethoscope on top of the fuel rail. All four injector have varying
frequency of noise the #3and#2 injector is the loudest of all four. my question is this a sign
of a bad injector?
