You could contact Derek at Vice Grip Garage on UA-cam. He rebuilt one with his Dad as a kid and just bought it back. He would be classified as close to an expert as you will find. Just a thought.
Just a small suggestion... When looking for metal parts (flakes) drain through an old style metal food strainer, and attach a magnet to the side. all the crap will go through and all the metal will attach to the strainer. you can even pour gas over it to give you a better view.
If pulling valve covers, I would put some oil on the top side of the engine, on the valve train and down the drainage holes of the heads. Change the oil and filter again with an oil additive. Don't give up on it yet.
Rods don't knock very long before they come apart. But solid lifters can knock for years so check the adjustment first. Runs smooth for a 65 yo engine!
The early hydraulic lifter Buicks and Oldsmobiles were noted for lifter clatter . If it has good oil pressure and you don't hear anything in the bottom end , it's most likely lifters or possibly fuel pump . It's doesn't seem to be missing so camshaft is probably ok . Keep changing oil and filter to clean out engine . Also you can short out one cylinder at a time and see if noise goes away to see if it is a rod .
My dad owned a 56 buick special. !!!!! If you get the vehicle to go over 25 or 30 miles per hr it will act as a clutch set up and turn the motor over !!!!!
Hey John enjoy your videos and nice shop. Derek from vice grip garage has one he built with his dad. If you have any problems he is a great guy and sure he could help with any problems you may have.
Worth fixing up and that wild piston has hole like that only reason could figure had drill or retap head for spark plug that broke so put new one in ! Or put a spark plugs in and threads were to big piston hit broke end of long time ago or drop something in to cylinder bang hard on when start up ! I surprise the motor didn't get stuck or seized or shake to left side bad like out balance to ! Hope when take motor out plus apart show what happened to !
Had a 54 just like that,same noise first start after 25 years,valve train noise went away after oil change and a little run time..Listen around fuel pump drive.
You might check with Dean on his ClappedOutClassics channel. He may have his nail head for sale or for parts. He swapped a modern LS or 350 in his 56 Buick.
Those Buick pistons had a weird design and I may be completely wrong but they had like a little hole that was cast into the tops of them, go do a google search you’ll see what I mean, it might have been For the straight 8 thought I can’t really remember, but might be some good news if it’s supposed to be there
It would have been good information to let us know what the compression was on the number 4 cylinder even with all the damage to the piston. It is unfortunate but fixable.
Hi,just started to watch your videos . Really enjoyed watching the work on your Buick.I remember you from high school or some where in Michigan.We haven't spoke in years. Im from Baycity and Pinconning.
Hey bud that hissing noise is the manifold sounds like the gaskets are bad. Tear off the exhaust manifold on both sides clean up the gaskets and throw some lube around it that should fix it. By the way new subscriber. Take care and god bless
What did the compression check reveal on the cylinder you were looking at? You didn't say. You said the first passenger side cylinder was 115 and then you didn't mention the rest just saying that you had a problem with the last passenger side cylinder. I presume it was a low number? Piston top can look bad but cylinder can have compression if rings/cylinder aren't damaged. What were the compression figures for the passenger side cylinders? Some things justify a rebuild, some don't.
If the next video says "we're probably going to drop an LS in it" I will throw up in my mouth, then suggest you sell it and buy a car more deserving of being hacked up.
I don't get it. You just show people a detonated piston(and that's what caused it, somebody running it on low octane fuel or had the timing too far advanced) and they still leave comments like water pump, fuel pump pushrod, timing chain, rod bearing...basically anything else that moves. No....it's the piston that has the crown burned away. When you hear that diesel-like sound from a gas engine you can nearly count on it being a piston moving around. Keep in mind that in '56 there were different compression ratios between Dynaflow and Syncromesh(manual trans) engines and between Specials(like that one) and Roadmasters. Your engine should have heads and pistons for 8.9:1 CR but I can promise you it's been rebuilt already with who knows what. P.S: you don't have to rely on a UA-cam "star" to advise you on Nailheads. Just obtain a copy of the 1956 Buick service manual...the one that GM printed in 1956, and it'll tell you everything you need to know about it. Good luck.
1956 had a weak cast piston and that’s what caused it I’m relying on a huge community of a lot of people to give suggestions I have the 56 book it’s an awesome car thanks for watching l appreciate everyone and all there help and suggestions
hi really hard to here you in the tin shed when your so far away from the mic it sounds like your talking into a bake bean tin have sound bar on at my end and makes no difference
@@RightOnJohn383 I hope you didn't do it when you first cranked on it. sometimes its best on those old ones to pull valve covers and make sure all the valves are free to move and no lifter,pushrod,rocker parts are siezed. as corroded as it was in there it appears to be an old wound though. hope the cylinder is salvageable.
@@RightOnJohn383 brrr, bout 30 in so Ohio, ur temps are coming tho. Scott's speed shop has a nailhead in the corner, an old drag eng if I remember right.
They don't make cars like this anymore. Unless your selling this car to someone who wants originality just put a more modern motor in it. Much more reliable

Those old '56 Buicks were pretty good cars, the engines are really stout for the time.
Yes they are truly a piece of American art that’s dying
I SWEAR! When I searched for this channel, I was *definitely* looking for car repair videos.
You can hone and repair just one cylindar, but lap all of the valves to bring compression back ... It'll be fine.
Rods don't knock very long before they come apart. But solid lifters can knock for years so check the adjustment first. Runs smooth for a 65 yo engine!

The part 2 shows what’s wrong with it
Liking the Buick 🖒 Well worth fixing 🖒🖒
Thank you for sharing information
The cover on the trans. Is for draining the torque converter on a full trans. Fluid change.
What a wonderfully large workshop!!!
Would probably run as smooth as could be also with a new timing chain & gears!
My dad owned a 56 buick special. !!!!! If you get the vehicle to go over 25 or 30 miles per hr it will act as a clutch set up and turn the motor over !!!!!
That’s cool I didn’t know that
It's worth fixing!

Buy a mechanics stethoscope. They do work.
Should. Have. Changed. Oil. Filter. And. Cut. Old. One. Apart. Look ed. For. Metal. In. It.
Best way to check for rod knocks old techniques in a young man love the vids brother
check the full pump return spring
You can try using paint strainer filters.
Had a 54 just like that,same noise first start after 25 years,valve train noise went away after oil change and a little run time..Listen around fuel pump drive.
This isn’t valve noise but that’s what I thought at first also
Pull one plug wire at a time - if you have a loose rod, knock will stop when power is removed..
Those old Buick’s always have noisy oil pumps
Nail heads were notorious for wrist pin noise....
Broom stick will keep your head out of the engine room when trying to find that there Knock’em

Yes they have a hole cast in the center of the piston but the edge of the piston is also broken
I hope you will be able to hone the cylinder wall, will you do a complete engine over haul?
Yes just not on a nailhead
Try the starter gear could make the sound
I wonder if coffee filters would work to filter oil

It was 0
When one changes oil on such an old car that has sat...is there something special to use other than a heavy weight?
Some people use motor flush before changing oil but I prefer letting it warm up then draining and then heavy weight on all my pre 70 cars
It could be the wrist pins.
use a paint strainer when looking for metal in your oil
that’s a great idea i dont know why I didn’t think of that
@@RightOnJohn383 That's comes from me twisting wrenches 25 years more than you LOL

Buick didn’t use exhaust gaskets pretty weird
And thanks for subscribing man god bless you too
air, fuel and spark
Oil filter is plugged up
It sounds like the water pump remove the fan belt and try it they can be very noisy sorry I was wrong
Does he fuel pump on a nailhead have the rod like a Chevy?
Low end knock/ 🤷♂️I've heard this before / put a quart of marvel mystery in the oil and drive it till it knocks it off 🤷♂️🤷♂️✌✌🐎🐎🐎
Pull off 1 plug wire at a time and if it’s a rod Baron it we’ll get loader
I show the problem at the end of the video
You got it✌✌
Rod ready to come through the piston

Compression on cylinder 4 was 0
Well in that case.... rebuild or crate motor time. I did like that scope.
I wish the lights on the scope were brighter
Great show from a happy new subscriber!
Thank you
Timing chain rattle?
You need to wear a mike on your collar sound is all over the shop
its called a nail head motor guys. im old, i know.
Yep it’s a 322 nailhead
What did You end up doing to it ?
timing chain slap?
Hole in piston
It's fun to interact✌👍👍👍👍
Not firing
Check plugs
Timing chain
what about the water pump
Lifters hidraulic valve are dry
Go to 455 Buick engine in it
322 is as big as I can go in a 56
great video.....
Thanks I appreciate it

Ok , I'll be first to say😁 LS it😁👊😎 good trouble shooting John 👍
It’s a torque tube lol I really thought about it

I wish I could but that would mean I have to do trans and rear end also because it’s a torque tube
Yeah that is definitely way more work. It's always easier to wish it than actually do it for sure. Lol
