I have been reading this forum for the last few years until today when I decided to register.I have 2 questions : 1)All of a sudden my engine started making this weird noise https://youtu.be/apuV89a7HAg .I did the 120k about 600miles ago.The only thing I couldn't do perfectly was to tighten the serpetine belts because the timing belt tension tool I had was not suitable.Could it be a damaged water pump due to a very tight belt? 2)I checked my ignition timing and it was set to 17 degrees.I redid it to 15 degrees,but now the problem is that the car won't idle perfectly(before it had no problem).Right now the whole car shakes at idle and the idle rpm fluctuates between 700 and 800 rpm.I tried to redo the idle using Consult but still the same.As soon as I set the timing to over 17 degrees it starts to idle again perfectly.I bought a vacuum tester and I will try to see if I can find any problem.
