Sorry it took so long to answer (Health issues lately). I had this issue with my 29-27 Buick years ago, but it was a 6 cylinder. I found this straight 8 photo online showing similar freeze plugs on the manifold side. If memory serves; the plugs are under a long side plate on the push rod side that requires removal of many machine screws. That plate prevents plug leakage to be seen and it directs any leakage via the roller lifters into the pan.

I had the same problem and used two new bolts welded to the original U part. I also had a couple of broken leaves in the spring stack. I had new ones made by a local industrial spring company that advised me to re-tighten the spring bolts after the first 100 miles. I was told that broken leaves are mostly caused by loose U bolts.

Kyle, I suggest you consider replacing it with the more common (original equipment) Stewart unit.

I have used Haggerty for over 20 years for all my collector cars. I have had two claims in that time and had no issues with their service.

Unfortunately, we have lost another great guy and supplier for hub pullers. https://www.legacy.com/us/obituaries/starherald/name/george-mcmurtry-obituary?id=36745167

This is a sign of weak fuel supply to the carb. I suggest you remove the bowl cover and watch the fuel level as you increase throttle to see if the fuel level is reduced while accelerating or increasing choke.

First I suggest you do a compression test and a leak-down test to determine if the rings & valves are sealing.

Running at half choke is a typical condition until the engine is fully up to temperature. If you are driving it less than a mile or so, it will not warm up enough to push in the choke.

Pete, Many (if not most) owner drivers replace the original cast iron pistons with aluminum pistons. This reduces the rotational weight of the engine and increases the original engine power by about 10%. Modern rings and wrist pins also reduce friction to increase power while reducing wear.

Most oil pumps cannot produce enough pressure due to wear on the flat plate that supports the gears. You can make the plate flat again to renew pressure by sanding or grinding. Just make sure it is smooth and flat when finished.

Does it turn over with the priming cups open?

A hand crank for a large series straight 8 engine is totally unnecessary. Jog the starter or pry on the ring gear to set timing etc. Just don't ever try to start it with a hand crank unless you want a hernia...

Graphite only...

Pull the string packing and measure it to determine the annular space size you need. Wrap the packing around the same size shaft or wood dowel and angle cut packing rings to fit tightly end to end on the pump shaft. Pre-lube with waterproof marine grease and insert three rings with cuts 120 degrees apart. pump packing | McMaster-Carr

I suggest you first check your freeze plugs for leaks.

Great parts cars or speedster makings... Looks like 1923 models?

Andrew, Perhaps a previous owner replaced it with a more common badge. McLaughlin badges are much harder to find.

Torque settings are also dependent on new or old (reused) fasteners. Reused fasteners are already stretched and will often fail before reaching their originally specified torque settings. Torque is also affected by weather the fastener is lubricated or not. Many old bolts do not have a raised machined mating surface that would qualify as a fastener for specific torque settings.

Check for a rusted-out cotter pin or disconnected valve.

Unless the switch is just to activate via a solenoid as above, the switch should be rated to exceed the 6V amp load. 6V systems require double the amps of 12V systems.

I have a Frigidaire fridge in my man cave at the Buick Barn. It still works too.

Take it easy Dave. Just kick back and watch the forum for photos and videos like the rest of us... Get well soon...

Dan, As far as I know, there are no plans or kits to replace the wood in these cars. Unless you are a skilled wood worker with all the shop tools needed to do compount curves, finger joints, etc..., you will be challenged beyond your limits. If the wood is good enough for patterns, you still have a chance to make it happen. Otherwise I suggest you find a GM body builder that has done other GM cars. Good luck,

I believe you guys are overthinking this process. Feel each rocker to find the ones no longer under tension. Or, you can watch the valves open and close as a helper jogs the starter. Adjust the loose ones and mark the adjusted ones with chalk as you continue to jog the engine and adjust until all rockers are marked as adjusted. Double check with an old (beat up) feeler gage with the engine running to verify they are correctly adjusted.
