I noticed what looks like a flat too, and exhaust seems to be off, which makes sense to get the oil pan off. One thing that I asked is what led you to removing oil pan, he originally said when he bought it he assumed a timing belt probably, then it turned out to be “play in bearings” … another deal is the pictures he’s sent, the car is in different locations on his property, so either he starts it and moves it(which assuming no due to the oil pan may be off still) or pushes it. So I’m awaiting a response from him.
If I feel comfortable enough I may haul a trailer down there & check it out.. but so far I’m very very iffy, overall very looks good. Just looking for some definite info on bottom end problem.
