OK, oil gauge and compression tester are on the way. I was able to determine cylinders 7 and 8 are bad. #7 spark plug was black and seemed a little oil fouled, and #8 was clean, but not combusting. I was able to pull plug wires 7 and 8 at idle and noticed no change in idle, so they're the bad ones.
The oil dummy light goes off right after starting the car, so I imagine the oil pressure is OK, but also noticed my oil filter is plumbed in 'full flow' and not bypass mode which has me thinking the oil filter could have gotten plugged and starved oil flow? Is the return into the block after the filter/gauge only feeding the valve train, or rods and mains also?
I will test compression and oil pressure when I get the tools, and plan to remove the rear valve cover and inspect the valve stems next before I remove the cyl head.
The engine doesn't blow smoke, but the engine was replaced about 15 years ago from a well running doner car. I don't know how many miles are on it.

Are the valve spring compressor tools available someplace? I have a contact coming over from the US in 2 weeks, so will ask him to put some tools and parts in his luggage
Thanks for the ideas guys. Mike

edit:
When I shut the car off, the oil filler vent smokes a little bit. Is this bad blowby, or normal since there is no PCV?

All stores except gas stations are closed on sundays in southern (and most) germany, but monday I will have some time and will try and get a compression tester locally and a 'USB endoscope'. The USB cameras are pretty cheap, and I can plug into the laptop. Then I can tell any passers-bye that the Packard is OBD conform, and I am reading trouble codes. haha
I had pulled the 4 rear plugs and none were damaged, so at least the combustion chamber carnage hasn't gotten too bad.

Now I'm a little confused, nothing showed up on inspection after removing the valve covers. I checked all the clearances cold, and the rear-most exhaust valve was .030 while all others were about .010-.014. I warmed up the engine, and reset the valve clearances, all springs and retainers seemed to be in order. No parts loose or missing. Noise and miss are still very much there. One cyl is definately not good. More noise with load, less noise at idle.
You know, I was at a show yesterday and thought about buying a compression tester, and didn't. Wish I had now....Anyway. I have to organize a place where I can do some longer term work on the car and remove the head and look at the valves. That job I did about 20 years ago as a teenager on my first packard...This packard I plan on putting back together
In good news, the girlfriend learned how to remove air filter, heater fan, and inner-fender splash guard, as well as how to cut new gaskets for the valve covers. Working on the car is a place where I can boss her around
Anyway, here is a video of the valves that doesn't really have the 'bad noise'.

Sound is still more of a clack clack than a deeper (Rod/Piston) tone, but now I am not so certain the problem lies in the valve train.
Oh, and in case anybody is in souther Germany and needs their Small Block Chevy repaired, go to Frankie's Garage. Nice guy. http://www.frankiesgarage.com
In german we say, 'keep your ears stiff' instead of 'keep your chin up' That's what I'll do!

There is a bit of a miss now, but not very bad. At idle the hood shakes a little, before I wanted to try balancing a nickle on the engine It does not seem to be spitting back up through the intake, so perhaps an exhaust valve...I reviewed my shop manual and parts list from the known suppliers. Parts don't seem too bad. Hope I can do this myself -with the help of my girlfriend
Just a sanity check here, driving 50 miles back home would be a bad idea without getting that valve secure. Correct?
Thanks for the 'virtual' support.

Re: Air Duct Vent Hose Question 54 Packard Clipper

I found that removing the blower motor and cage allowed me to get a hand inside the duct and thus allowed me to slip the hose over the duct. The duct that I have (Original?) was a little bit smaller and really tight to get on. I also put a large stainless steel hose clamp around the outside. OK, not OE, but keeps the hose on. I got the hose clamps at Home Depot.

That's aaawweeesome.
Just gave the car a spring wash and partial claybar and wax, but neglected the white walls...This is the answer I have been looking for. I don't think the magic bars are too expensive, 2-4$. Also good around the kitchen.
