wondering if STP was one of the villains?
not (IMG:style_emoticons/default/poke.gif) at americans, but you guys used to love that stuff.

Thank you for the feedback. A TRUE 50 thousand mile car, one owner, perfect compression and leakdown, old oil looked ok when we drained it, nothing in the strainer, engine had never been apart before, still has its colored vacuum lines. Dream come true for anyone (one would think). Took about 150 miles for the knock to start, so now the teardown to see exactly what happened. Sounds just like a rod knock to me, and the only thing that could have caused it in my opinion was the oil turning to acid

thanks for the vid. it was very interesting.
i resurected mine after 16 years asleep. you had me out there listening for rod knocks. (IMG:style_emoticons/default/sad.gif) (IMG:style_emoticons/default/smile.gif)

wonder what clutch you are going to find in there when you drop the motor. rubber core? but it probably would have exploded already!
35 years is a long time - pushing it in the storage stakes.
if the old guy had gone out and started it every now and then during the first few years of garaging it, which he might have, it would never have gotten properly warm and driven condensation out, which might also have made the oil problem worse? he might have created a moisture cycle situation?

what i heard about STP is that it was not very friendly to air cooled engines - which run hotter. i got the story years ago. STP can go acidic after exposure to high heat. people used to pour it into their worn out fords, holdens etc back in the 70s like there was no tomorrow. (IMG:style_emoticons/default/beerchug.gif)
