The '31 Ford Model A was running fine for a little bit, running and driving. But old cars will always surprise you!

This is common for Model As that have sat for a long time. I had to do it on my latest Fordor. I would say run lots of water thru the radiator & block a few times after you get it back together. Do not go too high a comp for an old engine ; 5.5 : 1. is OK ; If you go too high it will need shell bearings, new studs & nuts. Also, new heads are not cheap & I would consider leaving the head at low comp. The car is nearly 95 years old ; as you say once you start changing things, where to stop. The car looks good with the old disc wheels & old paint. Fix what is wrong & have fun using it. Cheers from NZ. Kiwi.
Hi Lynda, that's great advice. I think you'll be pleased to see how this project develops. Thanks for watching!
Thanks: Persistence pay's off, and you guy's know your stuff.😄
Thank you kindly!
On my 1930 Model A I have a “Lyon Head.” This enables my car to raise the compression to about 7:01 this is just enough…and also I have a downdraft carb too. Thanks!
My '31 Roadster wasn't 'all together' when I got it... bro-in-law took it apart and abandoned it. So, quite literally, got a basket case - several baskets. Running & driving now, final project (fingers crossed) is making the brakes actually stop the car reliably... Those radiator bolts were not correct... correct have cross-drilled bolt coming up from underneath, spring from the top, washer, with a castle nut & cotter pin. I think spring was broken because they were way too tight. The light sockets should not have required so much disassembly... focus screw/bulb socket do not need to be removed to remove wiring. I put a 6.0:1 high(er) compression head on mine... some say it provides 25% increase in HP; 40 to 50 - wo-hoo. Was noticeable. Enjoying the progress. Interested to see where you go with it.
Thanks for watching! The next video will be less wrenching and more driving for sure!
I had a Model A motor my brother had stored, in pieces, for right about 60 years. I wanted to see if I could re-assemble it and see if I could make it run once again. The idea was to assemble it like a depression era farmer might have using as few new parts as was absolutely necessary mostly to prove a concept. "These motors are pretty bullet proof" !!! This one was quite worn but all there. It still had Ford Script standard bore pistons and the cylinders were quite worn. It did have two broken head studs. I had good luck using a welder to remove them. Attach (weld) a flat washer to the broken stud. If it's broken below the head surface, just building it up with filler rod until you get a nice/good weld onto the washer. The washer allows you to fasten a larger nut to the stud. At least a 7/16" or 1/2" nut welded to the washer so you can get a decent size socket on the stud. The heat from the welding helps to bread the corrosion bond also. Like you said, I prefer Kroil so that's what I soaked it with for a few days first. One stud took two attempts but backed right out once we were able to get a good attachment with the welder. The higher compression head will add more pressure on your bearings so I would check them first to make sure they are up to the challenge. Check out my channel "Pappabob29" and look at "The Dearborn Granny" playlist to see the entire build. ;o) BTW, I plugged the lower water outlet hole and filled the entire block with white Vinegar. I have used the vinegar before in plumbing cases where rust was clogging steel pipes. The Vinegar dissolves the rust. Did the same thing to the head while plugging off the water pump opening. A baking soda rinse is good to neutralize. The vinegar is a different variety of acid. Acetic Acid, I believe.
Hi Bob, all good tips and suggestions! Thanks for watching!
Maybe remove number two or three spark plug then turn engine so a piston is at the bottom of stroke - stuff thin rope inside the cylinder then slowly turn the engine - the rope will compress against the head and probably force the head off the block.
That was plan B in case the head didn't break loose by cranking the starter. Thanks for watching!
Next time, to remove the head, try feeding a good length of rope into the cylinder via the plug hole. Hit your starter and it'll pop it right off. Good content.. There is also a drill bit and guide set available from some parts distributors that I've found to be a lifesaver when it comes to broken studs.
Funny you should mention that trick. We had the rope standing by just in case, but we didn't need it. About the drill guide- stay tuned for the next video! Thanks for watching.
@@horsepowerheritage8030 Ever since I did that on Roadworthy Rescues, Model A guys have been thanking for the tip, but the credit belongs to my dad for showing me that trick a zillion years ago.
Hi Maurice what a great post, I was impressed how easy it came apart, I've worked on cars half it's age and way more trouble with studs snapping flush with the block. Personally I would look into using the original head and see if you could skim it at all. Looking forwards to the reassembly. I noted another comment mentioned the fan could shatter, that happened while my father was working on a car unluckily it went through his forearm it's got to be changed for your own safety. Many thanks for sharing
Great feedback! Glad you enjoyed the video, thanks for watching!
I would also replace the original fan with an aluminium fan. The original fan can break off.
Great advice- and that's exactly what we did. The latest video is up now: kzhead.info/sun/bN6CpMiCb6KDm58/bejne.html
When you heat something, heat area around bolt, not the bolt itself.
Hi Brad, that may be good practice in some cases, but not here. If you doubt this, look at an inductive coil heater (such as the Mini-Ductor Venom) and see how they are used. Generally it's better to heat the fastener because it will heat much faster than a head or block, which require far more energy to heat to effect. Also, fasteners are ultimately sacrificial, unlike a cylinder head or engine block. The goal of the heat is to break the bond. However, sometimes, that doesn't pan out and you have to move to plan B. Such is life with a nearly century old car. Thanks for watching!
Your better off to use a left hand drill bit,and it will back it right out!!!
Hi Charles, I wish that were true in this case, but sometimes these old bolts and studs are just too stubborn. Thanks for watching!
Good vid. What rear tires are you running?
7.50x16 rear, 6.00x16 front. Thanks for watching!
When is your next video on this project?
Most likely in about a week. We've had nonstop rain which has prevented me from shooting some video. Hang in there!
Thought you bought a Stanley Steamer!
Hi Mark! Haha, yes, it did some steaming for sure! Thanks for watching.
Performance head !!
Thanks for that, Charles! Stay tuned
Keep r stock..
I would leave the original head.
