pinging from passenger side of motor when accelerating
I have started to notice this more prominently as I have been driving the car. When I accelerate I get a pinging sound from passenger side of engine. It kind of sounds like pre detonation, but there is no impact io the drivability or performance of the car.
I have tried various octane gases and tunes as well as checked for vacuum . Can not seem to find anything obvious. I did replace the timing chains, tensioners and guides last year. But when I was done I made damn sure the timing was on the money.
After reading something about how these 4.6 sohc engines can actually work their way out of timing, especially the passenger side...I wanted to get some suggestions.....gas this happened to anyone else? I am probably going to pull the engine this winter and install some hitech cams.
