you didn't disturb the fusible link box right by the battery right? The green link handles headlights and taillights (assuming that also covers the popup motors).
Late to the party on this, but Steffan Peterson @ starquestclassicparts.com has helped me out a bunch; he currently has a 240 listed on his site: https://www.starquestclassicparts.com/product/240mm-flywheel
When you list on ebay it gives the option to have AI write the description, which this very much sounds like, agree car looks nice, could've done a lot better with more details.
maybe I'm getting to old but the thought of getting into a black/black car on a 100 degree day doesn't sound great... imo they do look really look great in black as well as white (I'm biased!)
ah you're right on the chain tension and oil pressure, forgot about that. I guess I need to accept the fact I need to pull the motor, have a look, and plan on doing a rebuild.
Well maybe (hopefully) my original post was premature. I pulled the valve cover off and am seeing what I believe to be excessive slack in the timing chain that without much effort slaps against the side of the timing cover. I'd imagine this is too much play and could be an explanation for the knocking sound.
Here's a video of the knocking with windows down sitting in traffic: https://imgur.com/a/tgm9G5h
