very very loud injectors
I have searched this forum for information about injector noise but didn't find a post about how loud is too loud. My 86.5 just had the tb,wp,smog pump,hoses and belts replaced at 116k. Now I hear the injectors clicking. They are really loud. I thought it was lifters at first but when I use the long screw diver diagnostic tool, it was very clear that the noise was coming from the injectors. After completing the tb,wp, etc I changed the oil (mobil 1 15/50 my usual oil) and filter and put in a bottle of chevron techron injector cleaner in with a full tank of gas. Could the techron cleaner have cause them to make these loud clicking? If so what can I do to make them quit making so much noise? I used BG 44k before and do not recall this problem. Of coarse the front of the motor has quited down measurable with all the new stuff, so maybe this injector noise was there all along. I don't know. Any suggestions or comments would be appreciated.
Thanks
Thanks

This reminds me of a story..
Go for a ride in this gals car, its a 98 Sentra. Anyway just after shifting 2nd gear it sounds like the rear wheels are going to fall off as the rear wheel bearings are both humming and howling its almost hard to talk without shouting, so i said do you hear that noise, she says what noise , I said the rear wheel bearings, she says its been making that noise for a long time, so i just turn up the radio........ Oh boy.
So she leaves me the car, i replace both of the rear wheel bearings and the timing cover radial seal to fix the oil leak that puts her going to jiffy lube every 6 days for a top up....( its free to top things up she says) I go to test drive the car and now i tell her well your car doesnt leak anymore and the rear wheels are quiet..
BUT now the front wheel bearings are bad, this wasnt able to be heard untill the rears were replaced.
Anyway try to add about 6 oz of Marvel Mystery oil to a full tank of premium fuel......... more than likley the injectors are fine

Thanks for getting back to me on this. I appreciate the MARVEL MYSTERY OIL suggestion and I will try it. But the question is how loud is to loud for an injector to be? What problems do loud injectors cause? Is it a sign that these injectors are going to fail?
I don't mean to drag this out but I'm very paraniod that I'm going to be left stranded by the road side.
Thanks in advance.

Funny you should mention injector noise. I pulled my noisy smog pump during a TB job and when it was running afterwards, the first thing I noticed was the injectors clicking. They hadn't changed, but the background noise was reduced.
