I have an SC engine that has been stored fully assembled, minus distributor, in a dry garage and climate for twenty years. It was running before it was stored. I'll need some or all of it for my 2000, so I was wondering what it might look like inside after so long. I'm sure all the seals and rubber will need replacing, but do the bearings corrode in oil or break down with age? Would the missing distributor cause problems? Thanks in advance for any advice!
