Sat it on the bellhousing end after removing the studs and removed the pan. Lot of sludge in the pan but the upper crankcase looked pristine. This photo is to reference the oiling system.

I removed the front timing cover. Significant corrosion on the tubes to the block and behind the Water pump and the hose attachment. No surprises there. I will post pictures tomorrow.

One thing I found perplexing is the amount of slack in the timing chain. Are they prone to stretching? How are the replacements?

Here is some of the corrosion. Notice the water passage holes to the block

And the corrosion behind the water pump and the outlet pipe to the radiator

I'm almost certain the timing chain is easy.
What is more concerning is the timing cover...notorious for corrosion. A friend of mine went through this a year or so ago, thankfully the cover is reproduced as coolant in the oil is not a good thing. Start saving...not a cheap item.

Good news. I disconnected the rod/piston that I thought was the reason for the engine being stuck and it turned over beautifully.

Now just need to get that piston loose. I can now work on it from the crankcase side.

We have the timing chain for the V12. It is a precision made high quality piece that we have had made in the USA. If you are interest please contact our Packard Department.

Thanks

I am hand cleaning the engine using oven cleaner, carb cleaner and lacquer thinner, utilizing a pressure washer.

I am starting with the oil pan and it had what looks to be a casting date of 8-23-37. I guess that is right at the model year change.

The pan looked like the La Brea tar pits with the junk in it.

Exercise plenty of caution when using oven cleaner on aluminum, the active ingredient can vigorously attack it.
