I've been running with chips for a while. I'm making an assumption, but I feel a well thought out assumption based on my knock issue from the beginning of scanning that I've been running with a chipped piston for the entire time I've owned it. 30,000+ miles.
I'm going to put a piston in it against the advice of several on here; I plan on making sure that my clearances and torque specs are done properly.
The car is in the garage on jack stands right now; just need to find time and motivation in my currently busy schedule.
