I was talking to someone about my engine. Starting to think I should have replaced the pistons because they take a beating from the pressed wrist pin and can cause a knocking/klaking type sound at certain rpms under load.

Car never did this before the rebuild so I never thought of it. It also didn't start to do it for a little bit after I had it up and running. Possible conclusion that maybe tight rings and break in on the used pistons took their toll on it.

Who really knows.

Once I get that crank key replaced, I'll see if it changes anything, but it doesn't seem like it will.

Oy vey, I feel like such a tard. Damn K car.
