Hi all, I've been trying to hunt down a ticking/knocking noise in my m20 for a while now.
When I start the car from cold, there's a knocking/ticking noise coming from the bottom end. Got the proper spring tool to make sure I was properly adjusting the valves, the valve noise sounds much better, but the knocking sound persisted(I'll link an old video I took but it was before I properly adjusted the valves so keep that in mind).
Ended up pulling the spark plug wire on individual cylinders, and I found that when I disconnected the spark plug on cylinder 1, the sound pretty much went completely away, even when the engine was completely cold.
Do the symptoms I'm describing sound more like a piston slap, or rod knock, or something else?
Also, where do I go from here to repair the engine? Or will I most likely have to replace the whole bottom end. Should I take my car to a mechanic or machining shop?
