Started tearing down the Caddy cores I have. Decided to start with the the one out of the Eldorado because I will need the oil pan an pickup regardless.

Unfortunately, this one may be a goner. Lots of rust in the cylinders and heads. Obviously it sat outside with nothing on over the carb.

Inside the bore:

And inside the head was really rusty too.

There was a couple quarts of water in the pan also but the bottom of the engine had enough oil that it is not rusty. You can bore these things a LOT and I expect this can be saved but I'd rather start with a better candidate.

When I separated the case there was a surprise:

One of the three torque converter bolts was missing and the flex plate was really floppy. I'm sure it made noise.

But the real surprise was the bolt found in side the bell house. It was beat to hell and you could see where it had rubbed on things as it was coming out. No doubt in my mind it was a noisy mother and could easily have been the cause of the motor being pulled.

Looking past the rust, this motor has virtually no ridge in the cylinders and could easily have saved. Now the pistons will have to be beaten from the cores and I don't know what it will take to get the valves out.

So I've started on Caddy #2. Oil is relatively clean and no water in the pan. I'm optimistic this will be a better candidate.

The engine is free and turns over. I'll get it apart tomorrow. Hopefully I can get one good engine from these two. (I'm still hoping to do the 403 though)
