Greetings,
Hopefully the year is treating everyone well. The good news is my move to North Carolina went well and I have now tuned up the car after being in storage for 2 years. (sparks, wires, points, filters, etc.)
The bad news is it seemed to have developed a knock. Would appreciate any insight as to what could be causing this. I have a feeling I know but am trying to not to admit it. See (or hear) the videos below.
Thank you!
William

...In My Opinion...Based Only on the Sound; It Is NOT a Main Bearing, and NOT a Rod Bearing! The 'Tick' Could Be:
1. Exhaust LEAK
2. Loose Valve Adjustment/Failing Hydraulic Lifter
3. Fuel Pump EXCENTRIC
Was the Engine Running at Normal Hot Temperatrure? Lifters will Normally Make a Similar Noise (especially 'Solids'), Until fully warmed up And the oil Pressure is UP (Hydraulics).
Good Luck with It!
… Yes! It could be a Rod Bearing, Spun after sitting for years. Just starting to go and has found 'PLAY'. A 'Main' Bearing would sound like a Deep Rumble.
Thanks Marlin! That gives me something to look into. The engine had not been running for very long so don't know if there would be a temperature issue. I will start it up and run it a little longer. I take it you don't recommend I drive her yet?

To perhaps better locate the source, try a mechanic's stethoscope or a listening stick - piece of wooden dowel, touch it to various spots on engine until you locate and get closest to the noise source. Old broomstick works.
disconnect a spark plug wire at a time to see if the noise stops when a cylinder is not firing. a hollow tube works great for listening, you can hear the air moving though the ports, each individual rocker ...
Great suggestions! Thank you.
I'd bet on a stuck hydraulic lifter
I'm getting a stethoscope and will let you know what I come up with...
