Ticking noise from coils?
I changed my vcg yesterday and before I put everything back on like the plastic covers I was checking to make sure that the oil leak was fixed. I started the car and took it for a drive and when I got back I did a visual. Everything looked fine but I noticed a ticking sound coming from the coils. I thought it was just the front one but the sound was coming from each spark plug. I took a hose and listened closer and each 1 was making the noise. Car runs fine except for the ticking. I waited till dark to check if I could see any type of sparking that was coming off but nothing. Any suggestions?
