I finally got this on the engine stand, and pulled the pan ans one main, and one rod bearing.
I found the rod bearing all chewed up, and a small mark on the crank. Also I found some discoloration on the rear onf the crank where it goes into the rear seal. Can not feel anything but I see it.

So I guess I am at a crossroads and looking for advice.
the car is not worth 2K for a complete rebuild. I do not know what it costs to grind a crank, but the bearings are standard size. So just to replace that is looking like $200.00+ and if the rings are bad or anything else... I am thinking it is time to call it quits on this car, and start over on something else.
this is the 77 300D NA car.

give me your opinions on where this is headed and the cost. Knowing that this car, or it's replacement, will teach 3 more girls to drive.
Thanks
