Have a 53 Hydrive that was running when i bought it 2 years ago, but kinda sat ever since. I finally fixed the issue that was the reason it sat so long and went to change all the oil out this weekend and hopefully start it back up and found two new issues. One is that the washer the PO used for the oil drain pan doesn't even have enough copper to make a penny, which is probably why the engine loved to leak oil. But because this thing is so jerry-rigged, i have no idea what size washer i need to replace it with. the thing i pulled out was a paper thin circle that's all kinds of bent up.
Also, the PO went old school and cut the oil with kerosene. And its been sitting in there for the past 2 years. So I assume that my oil pan is going to be super clean. but do I need to worry about anything else being messed up now?
