Thought I would start a new thread on this.
I just changed my plugs which were initially installed by previous owner (NGK, Ford racing wires, MTD ignition). Supposedly they aren't that old, but I wanted to change them anyway. Based on feedback from most people saying to stick with autolite 25's, that's what I went with. Gaped all at .054 and installed them using same wires (look in great shape). Fired car up and immediately heard a ticking kind of like an exhaust leak tick. It was pretty loud when I took it down the street and back. Definitely coming from the passenger side back.
I thought I might have disturbed the smog pipe in the back of the motor, but it's pretty solid.
I pulled the plugs out and doubled checked gap (one might have been off a little). Made sure they were all snug, checked order of plugs wires and made sure I heard the "click" when pushing the wires on. I did notice the wires seemed to fit on the NGKs better than the Autolites, but that might just be me reaching.
Started car again and although the ticking was still there, did sound a little quieter.
I checked the plug length and the NGKs are actually a little longer so they can't be hitting.
I supposed it's possible to get a bum plug, but seems very unlikely. I did pick up two new plugs anyway so I can at least swap out #4 later. Worse case I'll put the NGKs back in and see if noise goes away.
Anyone ever experience this? Seems very strange. A quick google search yielded many experiencing this for all kinds of reasons.
I'm thinking bum plug or poor wire connection...
