Enjoy your Deeeluxe Packard

Joe,

How many vendors participate on this site giving advice and information and how many of them are up at 2:30 am doing so?

All the head stud holes go through to the water jacket, I've done many many engines and never used any sealant and never had a leak. Same for manifold studs.

CORRECTION : I NOW RECALL A FEW TIMES A SINGLE HEAD STUD LEAKED. I REMOVED IT AN PUT OLD FASHIONED PERMATEX WHICH DID THE TRICK. BETTER THAN HAVING HAD TO DO SEVERAL THOUSAND "JUST IN CASE"

A Packard always ran flawlessly whether cold or hot if everything is adjusted and operation properly. At idle poor running might be best described as a "rough idle". A stumble usually describes an attempt to move and a difficulty as when first accelerating and the car misses and runs poorly for a few seconds.

I do not believe that the miniscule amount of air coming through the tube when the choke is warmed up will cause a stumble. When the choke piston is at the bottom of its bore it closes off most of the air as I recall, when cold more air comes through to heat the choke spring. As far as the stumble, check engine vacuum at idle, should be 18/19 or so.

Stumble is likely the vacuum advance, check it. Also check operation of accel pump, gas should squirt out of both nozzles.

Let us know what you find.

A recent buildup of carbon is unlikely to be "baked on" and thus easy to remove. I've never needed anything more than a 1" or so paint scraper of a gasket scraper with a plastic handle. Bring each piston to TDC and in 4 minutes the piston and area around it is done. Some carbon will always build up, anything left will not be a problem. Make sure to remove any scrapings from the head gasket seal area.

If you fix the cause of the buildup (choke ??) and drive the car while gunning it under hard acceleration you will see black smoke, that will be the carbon being blasted off. About the only effect the carbon will have if left there is to boost the compression a bit and on a low compression Packard that's not a bad thing.

I know it feels real good to clean it off, enjoy.

Perhaps the reason we never experienced bearing failure problems is both Dan and I have small families affording us time and money to change our oil every 3000 miles, afford premium gas and quality oil.

Thanks for you endless contributions

HH,
In general what were the problems that Packard found that caused bearing failure/oiling problems other than the lifter problem.

Thanks

We have owned many many V8's since 1962 and driven some to over 100,000 miles. Never low oil pressure, never bad rod or main bearings. We have sold bearings for all 1935-56 Packards since 1960 and the V8's are by far the slowest sellers, even considering that they were made fro only 2 years.

The "problem" with the oil pump is not that it does not provide sufficient pressure/volume but that it ingests some air which gets trapped in the lifters causing the lifter noise problem.

We had a customer in Texas many years ago who had purchased a bunch of SASCO surplus new 352's and used them for his irrigation pumps. The ran them 24 hours a day during the season and called us for parts when the bores wore out too much. He said they were the best engines he ever had.

.060 mains are unavailable

There have been several early 120/six coupes on various sites that have been listed in these forums. The price range you could afford was up to $25,000 an most of these were well within that.

This car is near that already,and tjhe reserve has not been met. A few more bids and it will be out of your range so why worry about it.

As far as your question of how high the bidding will go, that's like asking how far the batter will hit a homer on his next time at bat.
