Thanx for the info. I changed #1 injector due to nailing. The "new" injector I got from FastLane nails even worse!!! Put my stethescope on #1 injector.... loud ticking... all other injectors are quiet. Before I get blind and rip out the pre chamber I am going to a local shop for pop test and spray test. I have 3 old injectors that I know need rebuilt. They can set #1 to MB specs, then I will install with new heat shield and with any luck #1 will be as silent as the other 4! I have searched the forum for other causes of nailing and it seems it is always the injector. With the stethascope you can hear slight valve rattle, but not without the scope. Above 1200 rpm it sounds great, pulls strong starts with only minimal shaking until warm... less than 1 minute.
