I didn't run the engine enough to monitor oil consumption between changes, but the little I did run it didn't have any glaring issues.

Do the rocker ARMS have a hole completely thru the push rod socket end of rocker arm?????


No, the arms don't have holes all the way through. Looks like the oil just leaks out instead of squirting everywhere.

Thank you Jack. I'm going to continue my inspections and report my findings as they come. I'm trying really hard not to slide down that slippery slope

I did a compression test last night. When last it ran, it seemed to run fine but it hasn't turned over for a couple of years and I was glad to find it wasn't stuck and the starter motor still managed to turn it over.

I did the first round just as the motor was left and the second test was with 3-4 squirts of oil in the cylinders.

Cylinder# Test-1/Test-2
1...............127 / 156
2...............127 / 152
3................97 / 120
4................80 / 125
5...............107 / 115
6...............100 / 132
7...............122 / 128
8...............108 / 145

I assume these results indicate new piston rings are needed? I was really hoping to avoid tearing this motor apart. Will these numbers improve when the motor is back running again or is that just wishful thinking?

Thanks Rik.


I pulled the rocker covers off and got my first look inside.

Looks like the valve seals are messed up. Passenger side look torn up. Drivers side look different. Like they were replaced in the past? I'll let you engine detectives take a look.

Body is already off the frame and I pulled the motor to change the transmission.

When the engine was last run, about 2 years ago, it ran just fine and I don't remember any glaring issues about it's performance.

I don't plan to rebuild the engine. But as long as it's out of the frame I figured that I'd take the opportunity to do some inspections.



Yes I was working on the Chevrolet tank for my Packard. I need to update that thread soon with some more information. I took about a year off from this project and am just now getting back in the swing of things.

Thanks for the great info PackardV8!!

Something to think about.

The lower half of the flywheel cover. Does it have a small hole in it?

The 56's had a window and a cover plate. It makes draining the torque converter easier. Maybe worthwhile change.

The bottom cover on my 55 Patrician, was drilled out (I assume) enough to let you get a socket in there to drain the converter. I did not know it until I saw other 55's.


Here's my flywheel cover.

Based on the oil pan, that engine has had lots of experiences; wonder what it would say if it could tell us?

For starters, drop the oil pan. Clean the oil pump intake screen. Pull at least a couple of main and rod bearing caps and check the bearing condition and clearances, and the crank journal condition (visual check). Pull the timing chain cover and check the condition of the timing chain and gears, replace the front seal. Sure, replacing the core plugs is a good idea.

If you haven't already done it, take a set of compression reading; first time dry, second time around after a couple of squirts of motor oil in each cylinder.

Remove both water jacket drain plugs and force-flush the cooking system.

Replace the water pump and fuel pump with rebuilt units.

Remove the valve covers and after a visual inspection, use a small and long cleaning rod and brush (such as one woulduse for a 22-caliber rifle) and clean both oil return drains from heads (at the rear) back down to the pan.

New motor mounts are available from Kanters, exact duplicate of originals and not expensive.


Thanks Owen! It's all on the list now.

What is your serial number? The red paint was commonly used on the '56 Studebaker Golden Hawk engines.

Yes, the pan has been repaired and no, the skid pan is a never-before-seen addition.

No, this isn't a Chevy - there is usually no problem with reinstalling the Packard exhaust manifolds. Did you break any studs when you removed the down pipes? The studs usually need replacing and that's a pain.

Yes, replace the core plugs.

Yes, pull the pan and the front timing cover. Verify your engine has the late cam retainer plate and spacer. Also verify which oil pump you have.

As far as what else to do, you're on a steep slippery slope.

1. New valve stem seals.
2. Pull the center main cap and check for signs of copper showing through on the bearing.

Engine block serial number 5522-6693 (same as the vin tag on the car)

All the exhaust manifold studs came out clean thank goodness. I'll probably take the manifolds off to clean them up in the blaster knowing re-installation won't be an issue.

Thanks Jack, I'll be posting my findings once I dive in.

The motor is out and on a stand. Don't want to waste this opportunity before putting it back in the frame. So what should a person do while the motor is easily accessable?

Pull the oil pan?

I kind of want to pull the intake and have it cleaned. There appeared to be some rusty junk in the runners when I took the carb off.

Check out the pictures of the brazing around the drain plug. This appears to be a repair. Also is the skid plate on the oil pan standard, or something added to cover a repair.

The motor mounts are also in need of replacement. I'm considering fabricating my own.

Someone poorly painted the motor black over the top of the original red/orange paint. I'm assuming the orange is original?

If I pull the exhaust manifolds off, will I get them back on? I've had problems with cast Chevolet manifolds not fitting back on the motor because they've shrunk from all the heat cycles.
