So here’s today’s update.
I’ve been worried to death over a tick that seemed to develop over the last couple days. Given past history, you can understand my concern. So tonight I climbed up under the hood and listened. Definitely on the pass side. Okay. Sounds like toward the front. Start cracking injector lines. 5, nope. 7 nope. 1 aha!! Seems like the tick goes away. Now. This begs the question if number 1 injector is making noise, could that explain the change in timing I found since I timed on #1 line? It was not ticking when I first timed it. Can someone refresh my memory on what causes fuel knock? Is it popping early or late?
A weak #1 injector makes total sense! An injector with a weak spring will open earlier and make the timing appear to be more advanced. Advanced timing will definitely rattle more. I think you nailed your timing mystery.
